Restriction of Conformation Transformation in Excited State: An Aggregation-Induced Emission Building Block Based on Stable Exocyclic C=N Group
Summary: The development of aggregation-induced emission (AIE) building block and deciphering its luminescence mechanism are of great significance.Here a feasible strategy for the FROSTY MINT construction of AIE unit based on E-Z isomerization (EZI) of exocyclic C=N double bond is proposed.Taking [1,2,4]thiadiazole[4,3-a]pyridine (TZP) derivative a
