Synthesis of 6'-substituted styryl indoline spirobenzopyrans

HUANG YI;LIU ZHIJIE

Published:1994-10-25

Abstract

Thirteen new compounds of the alkyl styryl indoline spirobenzopyrans were synthesized from the condensation of 2-methylene indoline with the designed salicylaldehyde. The spiropyrans with a nitro group at the benzopyran moiety showed reverse photochromic behavior, others were normal photochromic compounds. Meanwhile, it was found that the stabilization of the isomers of the compounds was not noly dependent upon the structure of compounds but also on the medium.

Key words: BENZOPYRAN, PHOTOCHROMISM, INDOLINOSPIROBENZOPYRAN PHOTOCHROMICS
