Synthesis of Imidazole-Based AIEgens with Wide Color Tunability and Exploration of their Biological Applications

Research on aggregation-induced emission (AIE) has become increasingly popular recently and various AIE luminogens (AIEgens) have been developed based on tetraphenylethene, hexaphenylsilole, distyrylanthracene, tetraphenylpyrazine, etc. However, facile tuning of the AIEgen emissions in a wide range remains challenging. Herein, a novel series of AIEgens is reported, based on imidazole-cored molecular rotors, with facile synthesis and emission colors covering the whole visible spectrum. Moreover, these imidazole derivatives exhibit biological functions unique among the AIEgens, including mitochondria-specific imaging and antifungal activity. Benefiting from the easy preparation and the tunable emission, the imidazole derivatives are expected to not only diversify the family of AIEgens but also enrich their biological applications.

Synthesis, Characterization and Corrosion Protection Properties of Imidazole Derivatives on Mild Steel in 1.0 M HCl

1-(2-Dodecylsulfanyl-ethyl)-1H-imidazole (DSEIm) and 2-Imidazol-1-yl-ethylsulfanyl)-acetic acid (ImESAA) were synthesized via radical catalysis method and characterized using H-1 NMR and C-13 NMR spectroscopy. The corrosion performances of mild steel specimens were studied by three imidazole derivatives include: 1-vinylvinylimidazole (VyIm), DSEIm and ImESAA, which were investigated in 1.0 M HCl using weight loss measurements, potentiodynamic polarization and electrochemical impedance spectroscopic (EIS) method. The results obtained show that DSEIm is the best corrosion inhibitor; its inhibition efficiency (E %) increases with increasing the inhibitor concentration, but decreases with the raise of temperature. Potentiodynamic polarization studies clearly revealed that the inhibitors changed the mechanism of hydrogen evolution, and that they acted as mixed inhibitors, but most effectively in the cathodic range. The higher values of activation energy (Ea) in the inhibited solution can be correlated with the increased thickness of the double layer; this is interpreted with physical adsorption of the inhibitor onto the metal surface resulting in the formation of a surface film. Adsorption of imidazole derivatives have been studied with Monte Carlo simulations.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 288-32-4. Recommanded Product: 1H-Imidazole.

Effect of 1-substituted imidazole derivatives for the curing process of epoxy-isocyanate composition

The kinetics of the curing process of isocyanate-epoxy materials hardened in the presence of 1-substituted imidazole derivatives was studied by the Coast-Redfern method. The extent of a conversion parameter of the curing process in two ways was calculated: DSC (peak area integration) and rheology (viscosity changes). The activation energy values were determined for epoxy-isocyanate cured in the presence of 0.5; 1.0 and 2.0 phr 1-substituted imidazole derivatives respectively. Increasing of accelerators amount results in decreasing the activation energy and other kinetic parameters.

Synthesis and biological activity of two oxireno-azecin-imidazole derivatives on perfusion pressure via guanylate cyclase inhibition

Some drugs have used in the treatment of heart failure; however, several of these drugs can produce secondary effects such as arrhythmia, hypotension and others. Therefore, the objective of this study was to synthesize two oxireno-azecin-imidazole derivatives (compounds 13 and 14) from two estradiol and estrone analogs through a series of reactions which involving; a) addition; b) acetylation; c) epoxidation; d) formation of two azecine derivatives; e) removal of silyl fragment of the azecines with hydrofluoric acid. Additionally, these compounds were confirmed by NMR spectroscopic data. Then, biological activity of the oxireno-diazepam-imidazole derivatives against perfusion pressure was evaluate in an isolated rat heart model, using the BAY-41-2272 (guanylate cyclase agonist), NS-2028 (guanylate cyclase inhibitor) and nifedipine (calcium channel antagonist) as controls. The results indicate that compounds 13 and 14 increased the perfusion pressure in the absence or presence of BAY-41-2272 and NS-2028; however, this effect was inhibited by nifedipine. These data indicate that compounds 13 and 14 could have a dual effect on perfusion pressure through guanylate cyclase inhibition and calcium channel type-L activation.

Ligand-controlled Assembly of Cd(II) Metal-Organic Coordination Polymers Based on 3,5-Dinitrobenzoate and Flexible Bis(imidazole) Derivatives

Three new Cd(II) metal-organic coordination polymers, [Cd(bbi)(DNBA)(2)] (1), [Cd(bbbi)(DNBA)(2)] (2), and [Cd(dmbbbi)(DNBA)Cl]center dot 0.38H(2)O (3) [HDNBA = 3,5-dinitrobenzoic acid, bbi = 1-(1,4-butanediyl)bis(imidazole), bbbi = 1,1-(1,4-butanediyl)bis(benzimidazole), and dmbbbi = 1,1-(1,4-butanediyl)bis(5,6-dimethylbenzimidazole)], have been obtained from hydrothermal reactions of cadmium(II) chloride with the mixed ligands HDNBA and the three structurally related flexible bis(imidazole) derivatives. Single-crystal X-ray diffraction analyses have revealed that the dinuclear cadmium clusters acting as nodes interlinked by two mu(2)-carboxylic groups, are connected to four other clusters through bridging bbi (for 1) and bbbi (for 2) units to generate two extended two-dimensional (2-D) networks. Compound 3 features a 1-D zigzag chain structure. A systematic structural comparison of the title compounds indicates that the conformations and the steric hindrance of flexible bis(imidazole) derivatives each play an important role in the formation of the Cd(II) coordination polymers. The thermal stability of 1 and 2, and the luminescence behavior of 3 were also investigated.

Solid state hydrogen bonding in imidazole derivatives: a persistent tape motif

The Cambridge Structural Database was mined for non N-substituted, neutral imidazole derivatives. Solid states with metal centres bound to the imidazole nitrogen atoms and ionic species were not included. The N-N, hydrogen-bound, tape motif was found to be a structural trend in the solid-state of neutral imidazole derivatives in the presence of possible competing hydrogen bonds and in highly steric environments. A chemically intuitive set of parameters was chosen to characterize the relationships between imidazole rings in the solid states. The choice of structural parameters and the values these parameters take as a function of substitution patterns of imidazole derivatives was discussed. The complexities that can arise in the crude extraction of hydrogen bond strength from solid state data was discussed.
