The azulene molecule features a unique combination of optical, luminescence, and stimuli-responsive properties. This makes the azulene motif a promising functional group to be introduced in photoswitches. Recent challenges in the field of photochromic compounds require the development of new approaches to molecules that are switched by visible light (400-760 nm), are proton responsive and have advanced luminescent properties. Merging azulene with photoswitches opens prospects for fulfilling these requirements. Herein, we highlight recent results on the application of this hydrocarbon motif in various photochromic systems, such as stilbenes, diarylethenes, and azobenzenes.
薁分子具有独特的光学、发光和刺激响应特性组合。这使得薁基成为在光开关中引入的有前途的功能基团。光致变色化合物领域的最新挑战需要开发新的方法来合成分子，这些分子可以通过可见光（400-760nm）进行切换，对质子有响应，并且具有先进的发光特性。将薁与光开关结合为满足这些要求提供了前景。在此，我们重点介绍了该碳氢化合物基在各种光致变色体系（如二苯乙烯、二芳基乙烯和偶氮苯）中的应用的最新结果。
