Anion and Substituents Effect on Spectral-Kinetic and Biological Characteristics of Spiropyran Salts

Spiropyran salts containing a cationic vinyl-3H-indolium moiety are characterized by NIR absorption and fluorescence of their merocyanine forms. This feature makes them promising fluorescent probes and markers for bioimaging. The article focuses on the synthesis and study of the spectral, kinetic an...
