biimidazoles have been structurally reported with two triphenylethylene units following chiral and cis–trans transformations simultaneously. Crystal structures show that the biimidazole ligand exhibits an (M)-trans-(P) configuration, whereas the (M)-cis-(M) mode was observed in the rhenium complex, showing cis–trans configurations between biimidazoles and the relative chiral isomers among adjacent triphenylvinylimidazole

乙烯基咪唑单元之间的相对手性异构体之间的构型。此外,为验证光谱行为与取向变化之间的关联规则,进行了荧光滴定实验以进行全面比较,其中
水相中炸药的检测性能取决于分子结构的改变,包括引入两个烷基链和fac- [Re(CO)3 Cl]。另外,对相关化合物具有不同扭转角的分子构象进行了计算研究。
