The fluorescence spectra of three rotational isomers of E-1,2-bis(2-anthryl)ethene (1) were obtained by the principal component analysis-self modeling (PCA-SM) method in solution. Based on the resolved spectra, the orientation of the rotational isomers in nematic and cholesteric liquid crystals (LC) were investigated. 1 mainly exists as the (s-trans, s-trans) conformer in these LC phases.
利用主成分分析-自我建模(PCA-SM)方法获得了 E-1,2-双(2-蒽基)乙烯(1)的三种旋转异构体在溶液中的荧光光谱。根据解析光谱,研究了旋转异构体在向列液晶和胆甾型液晶(LC)中的取向。在这些液晶相中,1 主要以(s-反式,s-反式)构象存在。
