合成了具有苯并噻吩基的四芳撑衍生物、4,5-双(2-甲基苯并[b]噻吩-3-基)-2-苯基噻唑、4,5-二(苯并[b]噻吩-3-基)-2-苯基噻唑并研究了它们的光致变色性能。这些光致变色分子在溶液和本体非晶膜中都显示出相当高的光反应性，并且显示出相对高的玻璃化转变温度。前一种分子即使在单晶相中也显示出光致变色反应性。
Terarylene derivatives having benzothienyl moieties, 4,5-bis(2-methylbenzo[b]thiophene-3-yl)-2phenylthiazole, 4,5-di(benzo[b]thiophen-3-yl)-2-phenylthiazole are synthesized and their photochromic properties are studied. These photochromic molecules show fairly high photoreactivities in both solution and bulk amorphous film, and show relatively high glass-transition temperatures. The former molecule shows photochromic reactivity even in the single crystalline phase.
