Abstract: Reactions of three pyrylocyanine dyes (derived from 2,4,6-trimethylpyrylium perchlorate) with p-toluidine and 2,4-diaminotoluene were studied to develop methods for detection of aromatic amines. The emission spectrum characteristics of the starting dyes and the final products obtained in solution and on silica gel were examined. The presence of open forms of the pyridocyanine dye in acetonitrile was suggested after analyzing the excitation and emission spectra of reaction intermediates. The formation of luminescent pyridocyanine in solution took several days, while its synthesis from the starting dye adsorbed on silica gel was completed within a few seconds.
