Synthesis of pyridine-functionalized cyclic aromatic triamide and formation of copper coordination polymeric complexes
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 Cu<sub>2</sub>I<sub>2</sub>(PPh<sub>3</sub>)<sub>3</sub> were characterized by elemental analysis and MAS <sup>31</sup>P 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.
