Supramolecular Structure and Circularly Polarized Luminescence Property of Chiral Perylene Diimide Derivatives

Abstract Chiral luminescent materials have wide application prospect in the field of optics .However the precise construction of circularly polarized luminescent materials and the elucidation of the intrinsic relation ship between their supramolecular structures and circularly polarized luminescence properties remain key sci entific challenges that urgently need to be addressed in the field of chiral luminescent materials .In this study we use perylene diimide (PDI) as the model compound to introduce chiral substituents and steric hindrance substituents into the PDI system and then synthesize two chiral PDI derivatives (namely POSS-PDI-B6 and C10C8-PDI-B6) with gelation property.Their supramolecular structures and photophysical prop erties were comprehensively characterized using ultraviolet-visible absorption spectroscopy fluorescence spectroscopy X-ray diffraction and circularly polarized luminescence spectroscopy respectively.The experimental
