on the photoluminescence quantum yields (PLQYs): the stronger the C–H⋯π interaction is, the higher the quantum yield (QY) is. In complexes 4–6, similar absorption peaks (1.10–1.30 THz) are mainly related to the C–H⋯π interactions, and strong absorption peaks (1.50–1.90 THz) are affected by the typical hydrogen bonds N–H⋯F/O and O–H⋯O. These results show that some weak interactions can be characterized
