Abstract
A series of new hydrazones based on 3,3-dimethyl-7-hydroxy-8-formyl-[2H]-1-benzopyran-2,1-[2]-oxaindane] with the substituents of different nature in the hydrazone moiety was synthesized. A comparative study of photochromism and complexation of the synthesized spiropyrans with a number of metal cations was carried out. Spectral and kinetic differences in photochromism and complexation of these compounds were revealed.
