摘要：

Thermally irreversible photochromic properties of indolylfulgenates, i.e. 2-allkylidene-3-[ 1-(1,2-dimethyl-3-indolyl)alkylidene] succinate esters were examined. A large indolylalkylidene group reduced the relative ratio of the colored species at the photostationary state of UV irradiation. Introduction of an adamantylidene group increased the bleaching quantum yield. The absorption maximum wavelengths of the colorless and colored species were shorter than those of the corresponding indolylfulgide.
