Delayed luminescence (DF), including phosphorescence and thermally activated delayed fluorescence (TADF), circularly polarized (CPL) exhibit common broad application prospects in optoelectronic displays, biological imaging, encryption. Thus, the combination of is attracting increasing attention. The encapsulation guest emitters various host matrices to form host-guest systems has been demonstrated be an appealing strategy further enhance and/or modulate their luminescence. Compared with conventional liquid crystals, polymers, supramolecular matrices, porous crystalline frameworks (PCFs) metal-organic (MOFs), covalent-organic (COFs), zeolites hydrogen-bonded organic (HOFs) can not only overcome shortcomings such as flexibility disorder but also achieve ordered guests long-term stability chiral structures, providing new promising platforms for development DF CPL. In this review, we provide a comprehensive critical summary recent progress photochemistry

Chirality inversion modulation is of great importance in the preparation chiroptical materials. The rational use stoichiometry mixed ligands chiral metal–organic frameworks (MOFs) to induce enantiomeric space groups a crucial topic structural chemistry. However, no remarkable results have been reported yet. In this work, we synthesized MOFs through assembly camphoric acid (d/l-cam) and achiral tetradentate ligands. Interestingly, visible single-crystal structures confirmed that chirality can be achieved via stoichiometric Significantly, switches circularly polarized luminescence (CPL) along with observed clearly. Moreover, encapsulated guest emitters exhibit inverted CPL, revealing helical-channel-dependent transfer. obtained constitute milestone field crystal engineering MOFs.
