Guo, Zhewen; Zhao, Jun; Liu, Yuhang; Li, Guangfeng; Wang, Heng; Hou, Yali; Zhang, Mingming; Li, Xiaopeng; Yan, Xuzhou published the artcile< Conformational effect on fluorescence emission of tetraphenylethylene-based metallacycles>, Reference of 184239-35-8, the main research area is phenylene bridged pyridyl platinum metallacycle preparation crystal mol structure; conformation fluorescence emission tetraphenylethylene phenylene bridged pyridyl platinum metallacycle.
Herein, the authors designed and constructed two metallacycles, 1 and 2, to illustrate the conformational effect of isomeric AIE fluorophores on the platform of supramol. coordination complexes (SCCs). Specifically, the dangling Ph rings in TPE units of the metallacycle 1 align completely outside the main cyclic structure, while in the metallacycle 2, these Ph rings align half inside and half outside. The exptl. results showed that two metallacycles exhibited different behaviors in terms of AIE fluorescence and chem. sensing, which could be attributed to the subtle structural difference of the TPE units. This work represents the unification of topics such as self-assembly, AIE, and chem. sensing, and further promotes the understanding for the structure-property relationship of isomeric AIE fluorophores.
