Hydrothermal syntheses, structures, and properties of the first examples of lanthanide 4-(4,5-diphenyl-1H-imidazol-2-yl)benzoate complexes was written by Wen, Hui-Liang;Wen, Wen;Li, Dan-Dan;Liu, Chong-Bo;He, Min. And the article was included in Journal of Coordination Chemistry in 2013.Formula: C22H16N2O2 This article mentions the following:
Three new lanthanide coordination polymers with 4-(4,5-diphenyl-1H-imidazol-2-yl)benzoic acid (H2PA), [Ln(HPA)3(H2O)2]·2H2O [Ln = Pr (1); Eu (2); Er (3)] were obtained by hydrothermal syntheses and characterized by single crystal x-ray diffraction, elemental anal., IR spectroscopy, and powder X-ray diffraction. Complexes 1–3 are isomorphous 2-dimensional supramol. structures, in which lanthanide ions are bridged by carboxyl groups of HPA– to form 1-dimensional chain structures, and the chains are further linked to 2-dimensional supramol. structures by hydrogen bonds. HPA– exhibit chelating and μ2-bridging coordination mode. The TGA of was carried out to examine the thermal stability and the photoluminescence of was investigated. In the experiment, the researchers used many compounds, for example, 4-(4,5-Diphenyl-1H-imidazol-2-yl)benzoic acid (cas: 5496-35-5Formula: C22H16N2O2).
4-(4,5-Diphenyl-1H-imidazol-2-yl)benzoic acid (cas: 5496-35-5) belongs to imidazole derivatives. Imidazole is the basic core of some natural products such as histidine, purine, histamine and DNA based structures, etc. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. Imidazole based anticancer drug find applications in cancer chemotherapy. It is used as buffer component for purification of the histidine tagged recombinant proteins in immobilized metal-affinity chromatography (IMAC).Formula: C22H16N2O2
