Circularly Polarized Luminescence from Schiff-base [4]Helicene Boron Complexes

Chem Asian J. 2023 Dec 22:e202301024. doi: 10.1002/asia.202301024. Online ahead of print.ABSTRACTBoron complexes with Schiff-base [4]helicene ligands were synthesized. These complexes were characterized by NMR spectroscopy and their helical molecular structures were unequivocally established by X-ray diffraction (XRD) analysis. The helical boron complexes exhibited efficient photoluminescence under UV irradiation, and the circularly polarized luminescence (CPL) properties were investigated for optically pure samples. Density functional theory (DFT) calculations were conducted to further understand their photophysical properties including chiroptical responses.PMID:38140756 | DOI:10.1002/asia.202301024
