摘要: 合成了一种含有光致聚合肉桂酸酯基团的新型光致变色螺吡喃染料,研究其与普通螺吡喃染料在不同高分子材料中的光致变色和热退色过程(PMMA和PVCi).通过UV-Vis光谱、NMR谱和IR光谱研究了新型染料中的肉桂酸酯基团的光致聚合过程,考察了其对螺吡喃结构的光致变色显色体热稳定性的影响.

关键词: 肉桂酸酯, 螺吡喃, 光致变色

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.

Key words: Cinnamate, Spiropyran, Photochromism
