Abstract

A novel bifunctional dye containing spirobenzopyran and cinnamoyl moiety was prepared and its behavior following irradiation with different UV lights (275/365 nm) was investigated. The colourless bifunctional dye in the film state exhibits photochromism through the colored merocyanine transformation of spirobenzopyran and photocrosslinking reaction in cinnamoyl moieties. The dynamic processes of decolorization was investigated by using the PMMA and PVCi film. The effect of photocrosslink on the stability of photochromism was considered from this study.
