And the article contained the following:

A urea-introduced imidazolium-based ionic liquid (IL), 1-butyl-3-{3-(3-methyl-2H-imidazol-1-yl)propyl}urea bis(trifluoromethylsulfonyl)imide (L1), whose selectivity to Pt(IV) and Pd(II) was changed only by a pH region, was synthesized, and its Pt(IV) and Pd(II) extraction behaviors were investigated. In the conventional organic extraction system, an organic extractant with a urea group, 1-butyl-3-(2-ethylhexyl)urea, in isooctane extracted Pt(IV) and Pd(II) in a similar pH range, the extraction equilibrium half-time (t1/2) of Pd(II) was 8.95 h. In contrast, in the IL extraction system, Pt(IV) and Pd(II) were extracted in the lower and higher pH regions, resp., indicating the mutual separation of Pt(IV) and Pd(II) by pH-change. Furthermore, the extraction equilibrium t1/2 of Pd(II) with the IL extraction system was 0.18 h. UV-visible and extended X-ray absorption fine structure spectroscopies of Pt(IV) and Pd(II) after extraction using the IL were conducted to determine the extraction mechanism. As a result, Pt(IV) was extracted as [PtCl6]2- via anion-exchange (outer-sphere complex). On the other hand, Pd(II) was extracted via a mixed reaction of ligand-exchange (inner-sphere complex) and anion-exchange. Finally, the IL extraction system did not produce a third phase even when loaded with a high concentration of Pt(IV). The experimental process involved the reaction of N-(3-Aminopropyl)-imidazole(cas: 5036-48-6).Synthetic Route of 5036-48-6

Liu, Kaixuan; Paulino, Victor; Mukhopadhyay, Arindam; Bernard, Brianna; Kumbhar, Amar; Liu, Chuan; Olivier, Jean-Hubert published an article in 2021, the title of the article was How to reprogram the excitonic properties and solid-state morphologies of π-conjugated supramolecular polymers.Application of 5036-48-6 And the article contains the following content:

The development of supramol. tools to modulate the excitonic properties of non-covalent assemblies paves the way to engineer new classes of semicondcuting materials relevant to flexible electronics. While controlling the assembly pathways of organic chromophores enables the formation of J-like and H-like aggregates, strategies to tailor the excitonic properties of pre-assembled aggregates through post-modification are scarce. In the present contribution, we combine supramol. chem. with redox chem. to modulate the excitonic properties and solid-state morphologies of aggregates built from stacks of water-soluble perylene diimide building blocks. The n-doping of initially formed aggregates in an aqueous medium is shown to produce π-anion stacks for which spectroscopic properties unveil a non-negligible degree of electron-electron interactions. Oxidation of the n-doped intermediates produces metastable aggregates where free exciton bandwidths (ExBW) increase as a function of time. Kinetic data anal. reveals that the dynamic increase of free exciton bandwidth is associated with the formation of superstructures constructed by means of a nucleation-growth mechanism. By designing different redox-assisted assembly pathways, we highlight that the sacrificial electron donor plays a non-innocent role in regulating the structure-function properties of the final superstructures. Furthermore, supramol. architectures formed via a nucleation-growth mechanism evolve into ribbon-like and fiber-like materials in the solid-state, as characterized by SEM and HRTEM. Through a combination of ground-state electronic absorption spectroscopy, electrochem., spectroelectrochem., microscopy, and modeling, we show that redox-assisted assembly provides a means to reprogram the structure-function properties of pre-assembled aggregates.

On January 27, 2021, Zhang, Huan; Yang, Shijia; Yang, Zhusheng; Wang, Dong; Han, Juanjuan; Li, Cuihua; Zhu, Caizhen; Xu, Jian; Zhao, Ning published an article.Safety of N-(3-Aminopropyl)-imidazole The title of the article was An Extremely Stretchable and Self-Healable Supramolecular Polymer Network. And the article contained the following:

The construction of a single polymer network with extreme stretchability, relatively high mech. strength, and fast and facile autonomous room-temperature self-healing capability still remains a challenge. Herein, supramol. polymer networks are fabricated by synergistically incorporating metal-ligand and hydrogen bonds in poly(propylene glycol) (PPG). The representative specimen, PPG-Im-MDA-1.5-0.25-Cu, shows a combination of notable mech. properties involving an extreme stretching ratio of 346 ± 14x and a Young’s modulus of 2.10 ± 0.14 MPa, which are superior to the previously reported extremely stretchable polymeric materials. Notably, the destroyed specimen can fully recover mech. performances within 1 h. The tunability of mech. properties and self-healing capability has been actualized by merely tailoring the content of a chain extender. The application of the as-prepared supramol. PPG network in constructing a flexible and self-healable conductor has been demonstrated. This strategy provides some insights for preparing extremely stretchable and self-healable polymeric materials. The experimental process involved the reaction of N-(3-Aminopropyl)-imidazole(cas: 5036-48-6).Safety of N-(3-Aminopropyl)-imidazole

On October 31, 2021, Ma, Youwei; Liu, Zhiyong; Zhou, Shuai; Jiang, Xuesong; Shi, Zixing; Yin, Jie published an article.Safety of N-(3-Aminopropyl)-imidazole The title of the article was Aminoesterenamide Achieved by Three-Component Reaction Heading toward Tailoring Covalent Adaptable Network with Great Freedom. And the article contained the following:

Covalent adaptable networks (CANs) have recently received extensive interests due to their reprocessability and repairability. Rethinking the libraries of the published CANs, most of them are fabricated by one/two-component reactions and few cases utilize multi-component reactions to construct CANs while multi-component reactions are conductive to tailoring the properties of polymers due to their structural designability and flexible choice of raw materials. A novel kind of dynamic covalent bond named aminoesterenamide is presented through three-component reaction between acetoacetyl, amine and isocyanate. Aminoesterenamide exhibits thermal reversibility through dissociating into vinylogous urethane and isocyanate. When it is used to prepare CANs, the synthesized polymer networks can be reprocessed many times via the exchange reaction between aminoesterenamides. Moreover, the forming of aminoesterenamide involving three starting components imparts CANs with great freedom to tailor their properties. Therefore, the authors believe this method that utilizes three-component reaction to fabricate CANs would bring new stories and perspectives to the exploration of new types of CANs. The experimental process involved the reaction of N-(3-Aminopropyl)-imidazole(cas: 5036-48-6).Safety of N-(3-Aminopropyl)-imidazole

And the article contained the following:

Polymer electrolytes with high Li+-ion conductivity provide a route toward improved safety and performance of Li+-ion batteries. However, most polymer electrolytes suffer from low ionic conduction, and an even lower Li+ ion contribution to the conductivity (the transport number, t+), with the anion typically transporting over 80% of the charge. Here, we show that subtle and potentially undetected associations within a polymer electrolyte can entrain both the anion and the cation. When removed, the conductivity performance of the electrolyte can be improved by almost 2 orders of magnitude. Importantly, while some of this improvement can be attributed to a decreased glass transition temperature Tg, the removal of the amide functional group reduces interactions between the backbone and Li+ cations, doubling the Li+t+ to 0.43, as measured using pulsed-field-gradient NMR. This work highlights the importance of strategic synthetic design and emphasizes the dual role of Tg and ion binding for the development of polymer electrolytes with increased total ionic conductivity and the Li+ ion contribution to it.

On April 9, 2021, O’Harra, Kathryn E.; Timmermann, George M.; Bara, Jason E.; Miller, Kevin M. published an article.Formula: C6H11N3 The title of the article was Designing Ionic Liquid-Derived Polymer Composites from Poly(Ionic Liquid)-Ionene Semi-interpenetrating Networks. And the article contained the following:

While the solvating power of ionic liquids (ILs) for a variety of solute types including polymers is well-known, the use of ILs as solvents for ionenes-charged polymers with cationic moieties within the backbone-has only recently begun to be explored. IL-ionene combinations offer vast possibilities to make iongels and perhaps even use ILs to exert control over ionene organization (i.e., coil or rod). If the IL solvent is also polymerizable, then poly(IL)-ionene semi-interpenetrating networks (semi-IPNs) can be achieved. This study reports, for the first time, examples of poly(IL)-ionene semi-IPNs formed by dissolving an ionene in a vinyl-functionalized imidazolium IL followed by subsequent photopolymerization of the IL around the ionene. The resultant poly(IL)-ionene semi-IPNs exhibit greater elasticity and ionic conductivity than the neat poly(IL). Thus, the addition of 10-20 weight % ionene can lead to significant changes in the properties of poly(IL) materials. Given the limitless possibilities for IL and ionene structures, this unique type of ionic composite presents vast opportunities for material design.

Wang, Huihuan; Li, Chuan; Hou, Zhuang; Li, Bolun; Cai, Haopeng published an article in 2022, the title of the article was A phosphorus-containing imidazole derivative towards the liquid oxygen compatibility and toughness of epoxy resin.Formula: C6H11N3 And the article contains the following content:

In order to develop a liquid oxygen-compatible (LOX-compatible) matrix resins for polymer-based fiber-reinforced composites, a novel phosphorus-containing imidazole derivative called VAD containing multifunctional groups was synthesized and used as a co-curing agent for epoxy resin (EP) with simultaneous LOX-compatibility and mech. improvement. A phosphorus group was introduced into the EP to capture the free radicals generated during the pyrolysis of the polymer to improve LOX compatibility, and the trimethylene group was introduced as a flexible spacer to enhance the toughness of the cured material. In comparison to pure EP, the modified EP with only 2.5 wt% VAD showed excellent mech. properties with 23.0% and 75.6% increase in tensile and impact strength, resp. Furthermore, as the content of VAD increased, a thermoset compatible with LOX (according to the liquid oxygen impact test) was obtained, and the flame retardancy was improved (according to the limiting oxygen index test). However, there was no significant sacrifice of transparency or thermal stability. In addition, the LOX compatibility mechanism was analyzed using XPS. As an efficient multi-functional modifier, VAD has a bright future in the modification realm of EP materials.

To prepare a robust material with high self-healing capability under ambient conditions is still a great challenge. Herein, a novel self-healing polyurethane is developed via a dual-dynamic network design, in which multiple H-bonding and metal-coordinated bonds (zinc-imidazole interaction) were incorporated into a polyurethane matrix. Benefiting from the dual-dynamic network, the synthesized metallopolymers exhibit excellent mech. properties, such as high tensile strength (from 6.68 MPa to 14.38 MPa), excellent stretchability (about 2000%) and superior toughness (from 55.61 MJ m-3 to 96.21 MJ m-3). Moreover, these metallopolymers show good self-healing capability. After healing under ambient conditions for 48 h, the tensile strength and strain at break of PU-IZ/Zn-0.50 can reach up to 7.13 MPa and 1800%, resp. The dual-dynamic crosslinked metallopolymers might provide a novel approach to design tough and self-healable materials for various industrial applications.

And the article contained the following:

The fabrication of high-performance thermosetting polymers with intrinsic flame retardancy and smoke suppression is necessary but challenging. Herein, we have successfully synthesized a liquid phosphaphenanthrene/imidazole-containing curing agent (DOPO-AI) for epoxy resin (EP) by the Atherton-Todd reaction of 1-(3-aminopropyl)imidazole (AI) and 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO). The as-prepared EP/DOPO-AI samples exhibit comparable mech. properties to the reference EP/AI-6 sample, with slightly decreased glass transition temperatures Impressively, the EP/DOPO-AI sample can pass the UL-94 V-0 rating and achieve a limited oxygen index (LOI) value of 37.0%. Addnl., the EP/DOPO-AI sample shows 26.3%, 36.6%, and 24.4% reductions in the total heat release (THR), peak of heat release rate (pHRR), and total smoke production (TSP) relative to the EP/AI-6 sample, indicating a significantly reduced fire hazard. The significant enhancements in flame retardancy and smoke suppression are attributed to the condensed- and gaseous-phase effects of DOPO-AI. This work demonstrates a feasible methodol. for creating high-performance EPs with inherent flame retardancy and smoke suppression, holding great promise in the future.

And the article contained the following:

Polydiacetylene based sensors were used for a variety of sensing applications. Here we demonstrate that diacetylene-containing amphiphiles could be spray processed to provide unique sensor coatings that may be applied to a variety of material surfaces. Utilizing an airbrushing technique, we examined processing parameters to yield spray-on sensors for detecting UV, temperature, as well as chem./solvent targets depending on the pendant side chain chem. of the resulting polydiacetylene coating. We observed that the concentration, carrier solvent, and UV exposure time had a significant effect on the colorimetric response of the sprayed on coating with better responses observed at higher amphiphile concentration and shorter polymerization times. We expect this approach to generating spray-on responsive coatings will provide a widely deployable means for detection that may be customized for a variety of sensing applications.
