enabled them to find widespread applications in the field of photochromism. Nowadays, bisthienylcyclopentenes (BTCs) present the most popular subfamily of these compounds, which are widely used as P‐type chromophores. This minireview summarises the main strategies for the synthesis of symmetrical and nonsymmetrical BTCs. In addition, attention is drawn to desymmetrisations achieved by monosubstitutions
双
芳烃具有独特的结构特性,这使它们能够在光致变色领域中找到广泛的应用。如今,双
噻吩基
环戊烯(
BTC)代表了这些化合物中最流行的亚家族,被广泛用作P型发色团。这份小型回顾总结了合成对称和非对称
BTC的主要策略。另外,提请注意由单取代实现的脱对称,尽管它可以是非常有利的,但是它不经常使用。一些作者的最新结果对此提供了支持。
