Imidazole derivatives: Thermally stable organic luminescence materials

A series of novel imidazole derivatives as optoelectronic materials were designed and synthesized. Photoluminescence (PL) properties of solution were investigated. The thermal analysis result indicated that these organic materials have better thermal stability with better PL properties. Due to the molecular structure introduced by imidazole heterocycles. The molecular structure not only changes the optoclectronic properties of the materials, but also enhances the thermal stability of the materials. The approach is helpful for the systematic investigation of structure-property relationship and thus for the design of novel and efficient organic optoelectronic materials. (c) 2006 Elsevier B.V.

Physicochemical and solvatochromic analysis of an imidazole derivative as NLO material

Bioactive imidazole derivative, 2-(2,4-difluorophenyl)-1-phenyl-1H-imidazo[4,54][1,10]phenanthroline, has been synthesized and characterized by IR, UV-vis, NMR and elemental (CHN) analysis. The electric dipole moment (mu) and the hyperpolarizability (beta) have been studied both experimentally and theoretically, which reveals that the synthesized imidazole derivative possesses non-linear optical (NLO) behavior. This chromophore possess more appropriate ratio of off-diagonal versus diagonal beta tensorial component (r=beta(xyy)/beta(xxx) = -0.19) which reflects the in plane nonlinearity anisotropy. Since they have largest mu beta(0) value, the reported imidazole can be used as potential NLO material. Within this context, reasonable conclusions concerning the steric hindrance in the chromospheres, push-pull character, hyperpolarizability of the imidazole and their application as NLO materials will be drawn. The solvent effect on the absorption and fluorescence bands was analyzed by a multi-component linear regression in which several solvent parameters were analyzed simultaneously.

Determination of imidazole derivatives by micellar electrokinetic chromatography combined with solid-phase microextraction using activated carbon-polymer monolith as adsorbent

In this study, an effective method for the separation of imidazole derivatives 2-methylimidazole (2-MEI), 4- methylimidazole (4-MEI) and 2-acetyl-4-tetrahydroxybutylimidazole (THI) in caramel colors using cation-selective exhaustive injection and sweeping micellar electrokinetic chromatography (CSEI-sweeping-MEKC) was developed. The limits of detection (LOD) and quantitation (LOQ) for the CSEI-sweeping-MEKC method were in the range of 4.3-80 mu g L-1 and 14-270 mu g L-1, respectively. Meanwhile, a rapid fabrication activated carbon-polymer (AC-polymer) monolithic column as adsorbent for solid-phase microextraction (SPME) of imidazole colors was developed. Under the optimized SPME condition, the extraction recoveries for intra-day, inter-day and column-to-column were in the range of 84.5-95.1% (<6.3% RSDs), 85.6-96.1% (<4.9% RSDs), and 81.3-96.1% (<7.1% RSDs), respectively. The LODs and LOQs of AC-polymer monolithic column combined with CSEI-sweeping-MEKC method were in the range of 33.4-60.4 mu g L-1 and 111.7-201.2 mu g L-1, respectively. The use of AC-polymer as SPME adsorbent demonstrated the reduction of matrix effect in food samples such as soft drink and alcoholic beverage thereby benefiting successful determination of trace-level caramel colors residues using CSEI-sweeping-MEKC method. The developed AC-polymer monolithic column can be reused for more than 30 times without any significant loss in the extraction recovery for imidazole derivatives. (C) 2015 Elsevier B.V.

Low-toxicity copper corrosion inhibitors

The efficiency of various imidazole derivatives as corrosion inhibitors for copper in hydrochloric and sulfuric acids (HCl and H2SO4) was investigated. Electrochemical measurements showed the organic compounds investigated have fairly good inhibiting properties, except for 4-methyl-5-imidazole-carbaldehyde in HCl. Protecting properties of most imidazole derivatives were close to those of commercial inhibitors for copper. Evaluation of the toxicity of the water solutions on the biological system for treatment of waste water – as measured in regard to chemical oxygen demands (COD), aerobic, and anaerobic toxicity – showed the tested inhibitors have relatively low toxicity.

Fabrication of one-component epoxy resin systems using maleic acid modified imidazole derivatives

A series of maleic acid modified imidazole derivatives (IM-MA, 2MI-MA and 2EI-MA) were synthesized via the Michael addition reaction of maleic acid (MA) with imidazole (IM), 2-methylimidazole (2-MI) and 2-ethylimidazole (2-EI), respectively. H-1 nuclear magnetic resonance (NMR), Fourier Transform Infrared (FTIR) spectra and Elemental analysis (EA) were used to verify the structure of maleic acid modified imidazole derivatives. The maleic acid modified imidazole derivatives were used as latent curing agents for epoxy resin (EP). Differential scanning calorimeter (DSC) under dynamic and isothermal condition was used to study the curing behavior of the prepared EP systems. The curing reactivity of maleic acid modified imidazole derivatives were significantly suppressed, compared with the common imidazole compounds. The EP systems containing maleic acid modified imidazole derivatives possessed excellent storage stability of at room temperature, due to the electron-withdrawing effect of carboxyl reduced the nucleophilicity of imidazole ring and the intermolecular hydrogen bond formed between carboxyl and 3-position nitrogen atom further restrained the nucleophilicity of imidazole ring. What’s more, the maleic acid modified imidazole derivatives regained fast curing ability towards EP under heating condition. Taking advantage of these characteristics, the maleic acid modified imidazole derivatives were suitable for preparing one-component EP systems.

Induction of non-diapause eggs by imidazole derivative KK-42 in the diapause type of Bombyx mori silkworm

The injection of an imidazole compound, KK-42, into fifth instar larvae of a silkworm (Bombyx mori, Daizo strain), which had been destined to produce diapause eggs, induced the moths to lay non-diapause eggs. The critical period for KK-42 injection in the induction of non-diapause eggs was 24 h to 72 h after the fourth ecdysis. Topical application of KK-42 to 48 h-old fifth instar larvae also induced non-diapause eggs.

Studies on anhydrous proton conducting membranes based on imidazole derivatives and sulfonated polyimide

Anhydrous proton conducting membranes based on sulfonated polyimide (sPI) and imidazole derivatives were prepared. The acid-base composite membranes show a good chemical oxidation stability and high thermal stability. The addition of imidazole derivatives in sPIs can improve the chemical oxidation stability of the composite membranes enormously, and even much better than that of pure sPI. The proton conductivity of a typical sPI/xUI(2-undecylimidazole) composite membrane can reach 10(-3) S cm(-1) at 180 degrees C under the anhydrous condition. The proton conductivity of the acid-base composite membranes increases significantly with increasing content of UI. Moreover, UI in sPI/xUI composite membrane is difficult to be brought out by the vapor due to the existence of long hydrophobic moiety, which will improve the stability and lifetime of the membranes in the fuel cells.
