Herein, chiral metal-organic frameworks (MOFs), DCF-20 and LCF-20, were utilized as matrices for both chirality transfer and energy transfer. HBT1@MOFs and HBT2@MOFs emit excitation-dependent circularly polarized luminescence (CPL) due to excited-state intramolecular proton transfer (ESIPT). HBT1/C152/NIR@MOFs exhibit full-color and white CPL. The luminescence dissymmetry factors () were significantly increased, benefiting from the efficient chirality space transfer and high luminescence efficiency.
在此，手性金属有机框架（MOF）DCF - 20和LCF - 20被用作手性转移和能量转移的基质。由于激发态分子内质子转移（ESIPT），HBT1@MOF和HBT2@MOF发出依赖于激发的圆偏振发光（CPL）。HBT1/C152/NIR@MOF表现出全色和白色CPL。得益于高效的手性空间转移和高发光效率，发光不对称因子（）显著增加。
