以吡咯为单位，合成了两种新的光致变色二芳烯同分异构体。研究了它们的性质，包括光致变色行为、晶体结构和荧光性质。这两种同分异构体化合物在溶液和单晶中表现出明显不同的光致变色性：一种在光环作用下变为红色，而另一种则变为蓝色，这可能是由于不同的取代基作用所致。
Two new isomeric photochromic diarylethenes with a pyrrole unit have been developed. Their properties, including photochromic behavior, crystal structures, and fluorescent properties, have been investigated. The two isomeric compounds show distinctly different photochromism, both in solution and in the single-crystalline phase: one turns red upon photocyclization whereas the other turns blue, which may be attributed to the different substituent effects.
