A series of new photochromic tetraarylethenes and their oxides have been designed and synthesized conveniently. When alternately irradiated by ultraviolet and visible light, their solution, solid powder and PMMA films can all switch reversibly between colorless and rare yellow. The typical aggregation-induced emission effect in H₂O-THF mixed solution was investigated in detail. It was found that these tetraarylethenes and their oxides exhibited different fluorescent changes in different media during photochromism. These compounds and the molecular designs are expected to provide some new options for the application of fluorescent molecular photoswitches based on simple structures.

方便地设计和合成了一系列新的光致变色四芳烃及其氧化物。当交替受到紫外线和可见光照射时，它们的溶液，固体粉末和PMMA膜都可以在无色和稀有黄色之间可逆地转换。详细研究了H ₂ O-THF混合溶液中典型的聚集诱导的发射效应。发现在光致变色过程中，这些四芳基醚及其氧化物在不同的介质中表现出不同的荧光变化。这些化合物和分子设计有望为基于简单结构的荧光分子光电开关的应用提供一些新的选择。
