摘要：
Five new representatives of donor-acceptor stilbazoles (styrylpyridines) were synthesized based on 2-oxo-4-(perfluoroethyl)-1,2-dihydropyridine-3-carbonitrile. The influence of the position (2-MeO, 3-MeO, and 4-MeO) and the nature of donor groups (MeO, Me2N) in the styryl part of the molecule on the photophysical parameters of compounds in solution was studied. Pronounced (fluoro)solvatochromism was revealed for the dye containing a 4-dimethylaminostyryl fragment, with absorption maxima located from 403 to 514 nm, and fluorescence maxima are in the range from 479 to 649 nm.
