In 2020,Journal of Materials Chemistry C: Materials for Optical and Electronic Devices included an article by Young, David C.; Tasior, Mariusz; Laurent, Adele D.; Dobrzycki, Lukasz; Cyranski, Michal K.; Tkachenko, Nikolai; Jacquemin, Denis; Gryko, Daniel T.. Application In Synthesis of Imidazo[1,2-a]pyridine-8-carbonitrile. The article was titled 《Photostable orange-red fluorescent unsymmetrical diketopyrrolopyrrole-BF2 hybrids》. The information in the text is summarized as follows:
The straightforward synthesis of structurally unique DPP-BODIPY hybrids was developed using unsym., imidazopyridine substituted diketopyrrolopyrroles (DPPs). These hybrids exhibit a superb combination of photophys. properties including high photostability, good fluorescence quantum yield as well as markedly bathochromically shifted absorption and emission compared to conventional diketopyrrolopyrroles. Increasing the size of the imidazopyridine substituent and/or the electron donating power of the other aryl substituent can further red shift both absorption and emission to reach ∼650 nm for the free-base and ∼700 nm for B-chelates. A strong intramol. H bond is responsible for the small change in geometry between the ground and excited states and hence relatively small differences in photophys. properties upon formation of B-chelates are observed The solvent dependence of the photophys. properties for the free base and DPP-BF2 complexes were studied and show strong fluorescence with long lifetimes in both nonpolar and polar aprotic environments. In addition to this study using Imidazo[1,2-a]pyridine-8-carbonitrile, there are many other studies that have used Imidazo[1,2-a]pyridine-8-carbonitrile(cas: 136117-70-9Application In Synthesis of Imidazo[1,2-a]pyridine-8-carbonitrile) was used in this study.
Imidazo[1,2-a]pyridine-8-carbonitrile(cas: 136117-70-9) belongs to imidazoles.Imidazole rings are also present in imidazole ring alkaloids, which are potential therapeutics for thrombosis, cancer and inflammatory diseases.Application In Synthesis of Imidazo[1,2-a]pyridine-8-carbonitrile Although other azole heterocycles are ubiquitous in a wide range of biologically active natural products, imidazole rings occur predominantly in the natural amino acid histidine.
