Abstract

A series of N-substituted indoline spiropyrans was synthesized containing a furan fragment condensed to the benzopyran part of the molecule. The structure of the obtained compounds were established by IR and multinuclear NMR spectroscopy. The influence of both the annelated benzene ring and the bulky N-benzyl substituent on the photochromic properties was studied in solution, as well as in polymer matrix. The process of thermally induced isomerization of the N-benzyl derivative was investigated by means of dynamic NMR.
