Hierarchical chiral MOFs with the induced chirality of AIE ligands exhibiting non-reciprocal CPL

Two pairs of chiral MOFs with hierarchical chiral structures were constructed through assembly of achiral AIE-type multidentate linkers and chiral camphoric acid. Non-reciprocal circularly polarized luminescence (CPL) can be observed on the macroscopic due to the coexistence of optical anisotropic and chiroptical nature. This study provides a new perspective to recognize and construct chiral crystalline materials. Two pairs of chiral MOFs, DCF-15/LCF-15 and DCF-16/LCF-16, were constructed through assembly of achiral aggregation-induced emission (AIE)-type multidentate linkers (TPPE and TPA) and chiral camphoric acid (d/l-cam), exhibiting non-reciprocal CPL.
