Supramolecular Structure and Circularly Polarized Luminescence Property of Chiral Perylene Diimide Derivatives
摘要
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 results demonstrate that both POSS-PDI-B6 and C10C8-PDI-B6 are capable of forming luminescent gels.Un-der the synergistic effects of steric hindrance from POSS and alkyl chain substituents,as well as chiral induc-tion from the B6 substituent,the PDI derivatives can assemble into helical supramolecular structures with chiral characteristic,thereby endowing the PDI gels with excellent circularly polarized luminescence proper-ty.These results provide valuable theoretical and experimental reference for the design and preparation of chiral optical materials.关键词
