Synthesis of new spiropyranes and study of the effect of the nature of substituents on their photochromism and complexation
摘要:
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.

tBu, Сl, NO2) were synthesized and studied with the help of IR, UV/Vis, and NMR spectroscopy. It was shown that in contrast with mother spiropyran existing in closed spiro-form, all the compounds in the solution (DMSO, acetonitrile) and in solidstate exist in thermodynamically stable merocyanine keto-enamine tautomericform due to migration of the proton of 7-hydroxy group to azomethine nitrogen, conjugated

A series of hydrazones based on a new spiropyran oxaindane series was synthesized. The compounds were found to possess photochromism and are characterized by a high rate of spontaneous decoloration of their photoinduced merocyanine form. Dark and photoinduced formation of complex compounds in the reaction of metal ions with molecules of the hydrazones in solution was observed.
