Biphen[3]arenes based on V-shaped units: synthesis and macrocyclization-enhanced thermally activated delayed
None:
A new class of thermally activated delayed fluorescence (TADF) macrocycles is reported. Among them, cyclic trimers (biphen[3]arenes) based on V-shaped units were synthesized for the first time. And all trimeric macrocycles show macrocyclization-enhanced TADF, where the quantum yield greatly increased from 36.8% to 70.9%.

Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
