Abstract
The article presents a method for the construction of a new tricyclic system of imidazo[1,2-b]pyrido[4,3-e][1,2,4]triazin-6(7Н)-ones based on subsequent reactions of the obtained 1,2-diamino-4-phenylimidazole ethyl ether of 3-methyl-6-phenylimidazo[1,2-b][1,2,4]triazin-2-carboxylic acid with dimethylformamide dimethylacetal and primary amines. The structures of the obtained compounds were confirmed using the data obtained by 1 Н and 13 С NMR, HRMS, and XRD. We analysed the dependence of the absorption and photoluminescence spectra on the structure of the compounds obtained using methods of quantum chemistry. The theoretical results were compared to the data of a real experiment. The article suggests a range of practical applications for imidazo[1,2-b]pyrido[4,3-e][1,2,4]triazin-6(7Н)-ones.
