Macrocyclic Hosts Featuring a Tetraphenylethene‐Embedded Skeleton: From Molecular Design and Photophysical Properties to Applications

Aggregate, Volume 6, Issue 11, November 2025.
The orthogonal integration of tetraphenylethylene (TPE) and its derivatives into the frameworks of five conventional macrocyclic hosts has garnered significant attention in the field of macrocyclic chemistry. This minireview systematically categorizes TPE‐embedded macrocyclic hosts into three types: non‐, semi‐, and full‐TPE‐embedded skeleton based on ...
