已经制备了四种具有延长的π-共轭噻吩并[b]噻吩单元的光致变色三萘嵌苯。根据噻吩并[b]噻吩单元的位置，排除光致变色环环化和环化回复行为。监测涉及热和级联环化回复的自发褪色反应，具体取决于分子结构。已经进行了电化学和计算研究，以阐明两种异构体中基态和阳离子态的相对稳定性。
Four photochromic terarylenes having extended π-conjugated thieno[b]thiophene units have been prepared. Photochromic ring-cyclization and cycloreversion behaviour are excluded depending on the position of thieno[b]thiophene units. A sponteneous fading reaction involving both thermal and cascade cycloreversion depending on molecular stucture is monitored. Electrochemical and computational studies have been conducted to elucidate the relative stability of their ground and cationic states in both isomers.
