合成了四个具有吡咯和可变芳基单元的新型不对称二芳基乙烯。系统地研究了它们的晶体结构和光致变色性能，以阐明芳基单元的芳香稳定能(ASE)的影响。实验结果表明，它们的热稳定性以及环化量子产率、光转化率、荧光调制效率和抗疲劳性与ASE具有很强的相关性。
Four novel asymmetrical diarylethenes with a pyrrole and a variable aryl unit have been synthesized. Their crystal structures and photochromic performance were systematically studied to elucidate the effects of the aromatic stabilization energy (ASE) of aryl units. Experimental results showed that their thermal stability as well as cyclization quantum yield, photoconversion ratio, fluorescence modulation efficiency, and fatigue resistance exhibited a strong correlation with ASE.
