二芳烯不仅在溶液中，而且在单晶中也发生热不可逆和抗疲劳的光致变色反应。本文介绍了二乙烯衍生物单晶光致变色的最新进展。重点研究了它们的晶体结构与光致变色性能之间的关系。光环化/环还原量子产率、吸收光谱、吸收各向异性和表面形貌变化强烈依赖于晶体中分子的构象和堆积结构。
Diarylethenes undergo thermally irreversible and fatigue-resistant photochromic reactions not only in solution but also in the single-crystalline phase. This article describes recent development of the single-crystalline photochromism of diarylethene derivatives. We focused on the relationship between their crystal structures and the photochromic performance. Photocyclization/cycloreversion quantum yields, absorption spectra, the absorption anisotropies, and surface morphology changes are strongly dependent on the conformations and packing structures of the molecules in the crystals.
