Delayed Fluorescence Behaviors of Aminopyridine Oligomers: Azacalix[n](2,6)pyridines (n=3 and 4) and Their Linear Analog
Aminopyridine oligomers exhibited long-lived emission at 77 K, which could be assigned to the delayed fluorescence. The macrocyclic structure predominantly dictated the emission behaviors. Their emission behaviors were elucidated from time-dependent density functional theory calculations.
