Abstract Pyridine-functionalized cyclic aromatic triamide (C3A-1EPy) was synthesized by Stille cross-coupling reaction and the chiroptical properties of the separated enantiomers were investigated using CD and CPL spectra. Two copper coordination polymeric complexes (C3A-CuP A and C3A-CuP B) obtained by reacting C3A-1EPy with CuI and Cu2I2(PPh3)3 were characterized by elemental analysis and MAS 31P NMR as well as XPS spectra. Although TADF and CPL were not achieved, room-temperature red phosphorescence was observed at 641 and 630 nm in powder state, and it was found that the emission behavior (wavelength, quantum yield, and lifetime) of C3A-CuP B depends on the optical purity of the ligand.
