As future energy-saving optoelectronics, bistable electrochromic (EC) materials/devices have high energy efficiency for potential applications as smart windows, displays, and information/energy storage, due to their ability to maintain optical states without consuming energy. However, further development is hindered by the lack of in-depth understanding of related key factors and universally applicable design strategies to achieve bistability. Herein, we report a new strategy based on active energyexchange with the aid of proton-coupled electron transfer, which can dynamically adjust the HOMO /LUMO energy levels of materials to obtain good bistability from traditional nonbistable materials. This strategy was thoroughly studied and proven by taking quinone derivatives and bromocresol green derivatives as examples. The device obtained after further polymerization and optimization showed remarkable bistability, coloration efficiency, and application potential for energy-saving flexible displays. The success, challenges, and cognitive gains of this strategy not only accelerate the development of various energysaving optoelectronic materials/devices, but are also likely to stimulate progress in physics, chem., and materials. In the experiment, the researchers used many compounds, for example, 1-Butyl-3-vinyl-1H-imidazol-3-ium hexafluorophosphate(V) (cas: 915358-85-9Computed Properties of C9H15F6N2P).

Ionic liquids (ILs)-based organic-inorganic nanocomposite materials are a new class of hybrid materials which can be used in lithium batteries, fuel cells, dye-sensitized solar cells and pressure sensors. Halloysite nanotubes (HNTs, Al₂Si₂O₅(OH)₄·nH₂O) are hollow like aluminosilicate clay, similar to commonly used platy clay kaolin, which open up various attractive applications including catalysis, anticorrosion, adsorbent, drug delivery, enzyme immobilization, fiver spinning and so on. However, the inorganic characteristics of clay-based halloysite nanotube result in a limited application in electronic field, making it difficult to capture attentions as extensively as carbon nanotubes. Herein, we develop a feasible and versatiel approach to prepared ILs grafted HNTs, by coupling the arylboronic acid and Al-OH groups on the HNTs. ILs are grafted to the modified HNTs via a typical atom transfer radical polymerization (ATRP) method.

Inverse gas chromatog. (IGC) was used as a tool to evaluate the surface parameters of three poly(1-alkyl-3-vinylimidazolium hexafluorophosphate) (P[C_nVIM][PF₆], n = 2, 4, 6) materials that were obtained by a free-radical polymerization IGC characterization was carried out at temperatures ranging between 303.15 and 343.15 K for determining the dispersive free energy (γ_ds) as well as the Lewis acidity and basicity parameters of the three materials. The retention behavior of the probes on the surfaces of the three materials was analyzed by plotting the net retention volumes (Vn) of the probes as a function of temperature The dispersive free energy results revealed that all three materials have high γds values and that the γds value decreases in an almost linear fashion with increasing temperature The acid-base data for the three materials confirmed that the surfaces of all three materials can be considered to be amphoteric with a predominantly basic character and that the basicity decreases with increasing alkyl side chain length on the imidazolium backbone.

We identified and explored the structure-activity relationship (SAR) of a novel heterocyclic chem. series of arenavirus cell entry inhibitors. Optimized lead compounds, including diphenyl-substituted imidazo[1,2-a]pyridines, benzimidazoles, and benzotriazoles exhibited low to sub-nanomolar potency against both pseudotyped and infectious Old and New World arenaviruses, attractive metabolic stability in human and most nonhuman liver microsomes as well as a lack of hERG K + channel or CYP enzyme inhibition. Moreover, the straightforward synthesis of several lead compounds (e.g., the simple high yield 3-step synthesis of imidazo[1,2-a]pyridine I) could provide a cost-effective broad-spectrum arenavirus therapeutic that may help to minimize the cost-prohibitive burdens associated with treatments for emerging viruses in economically challenged geog. settings.
