Abstract

A number of photochromic indolinespirochromenes containing a phenyl or p-methoxyphenyl substituent in the 5′ position of the indoline portion of the molecule were synthesized. The introduction of an aryl substituent in the 5′ position gives rise to a slight bathochromic shift of the longwave absorption band of the merocyanine form of the spirochromene.
