合成了一种由噻吩环、苯环和它们的桥组成的小分子硫杂[3]间环[2]噻吩并吩芬-1-烯（cyclophane），并显示出光致变色性;而一种带有长桥的间环噻吩并吩芬-1-烯（metacyclothiophenophan-1-ene）由于三个双键之间的共轭作用很小，通过密度泛函理论（DFT）计算估计是非光致变色的。
A small thia[3]metacyclo[2]thiophenophan-1-ene, cyclophane composed of a thiophene ring, a benzene ring, and their bridge, has been synthesized and displays photochromism, while a metacyclothiophenophan-1-ene bearing a long bridge was non-photochromic due to little conjugation between three double bonds, that was estimated by DFT calculations.
