A class of metal halide-based metal-organic frameworks (MOFs) materials with multicolor tunable long-lasting emission and white light properties were synthesized by self-assembly of 15-crown ether-5 (CE) ligands and metal halide salts (CdX2), resulting in three complexes (15-5-CdCl2, 15-5-CdBr2, and 15-5-CdI2). In the solid state, the complexes (15-5-CdCl2, 15-5-CdBr2, and 15-5-CdI2) all exhibited near-standard white light emission under 340 nm ultraviolet radiation at room temperature, with CIE coordinates of (0.28, 0.32), (0.31, 0.39), and (0.30, 0.34), respectively. Simultaneously, they exhibit excitation-dependent room-temperature phosphorescence (RTP) ranging from blue / cyan to green / yellow, with 15-5-CdCl2 and 15-5-CdBr2 exhibiting multicolor tunable and visible light luminescence (LPL) with time-resolved luminescence lifetimes as high as 1-2 seconds. Single-crystal X-ray diffraction analysis and theoretical calculations indicate that the bright LPL of 15-5-CdCl2 and 15-5-CdBr2 originates from the aggregation state induced by the 15-crown ether-5 ligand and halogen bonds. The LPL obtained in this way can be widely used in lighting and display devices, optical recording devices, biological imaging, security systems, and other fields.
