Novel xanthene-like dyes: synthesis and spectral properties

New xanthene-like dyes were synthesized by the reaction of N -[(9-chloro (bromo)-2,3-dihydro-1 H -xanthene(chromen)-4-yl)-methylene]- N -methylmethanaminium perchlorates with CH-acids. The presence of two electrophilic reaction sites allows the selective modification of the structure to form dyes wi...

Zusammenfassung:New xanthene-like dyes were synthesized by the reaction of N -[(9-chloro (bromo)-2,3-dihydro-1 H -xanthene(chromen)-4-yl)-methylene]- N -methylmethanaminium perchlorates with CH-acids. The presence of two electrophilic reaction sites allows the selective modification of the structure to form dyes with predicted photophysical properties. Dyes with a five-membered annulated aliphatic cycle can be used as organic fluorophores, and dyes with a seven-membered annulated aliphatic cycle as light filters. Graphical abstract
