Abstract

A method was developed for obtaining salts of all isomeric anisidines containing 2-(dicyanomethylene)-5-methyl-6-phenyl-1,2-dihydropyridine-3,4-dicarbonitrile as the organic anion. Studies of their photophysical properties revealed that they exhibit unique solid-state fluorescence parameters, which can be used for the spectrofluorimetric determination of the position of functional groups in isomeric anisidines.
