Abstract: A 3D imidazole-bearing cyclophane cage L1 was synthesized as trivalent cationic templates to react with metal halide to obtain a novel organic-inorganic crystalline hybrid: {[CdI4]3·(L1)2} (1). Its crystals have been grown by slow evaporation method and characterized by single-crystal X-ray diffraction analyses, infrared spectra (IR) and powder X-ray diffraction (PXRD). More importantly, the fluorescence property in solid state was studied and found the quenching efficiency is good and it can be used as a recyclable luminescence sensor for Fe3+ ions with high selectivity and stability.

Keywords: Trivalent cyclophane cages, organic and inorganic hybrids, fluorescence properties
