New 3 D Tubular Porous Structure of an Organic-Zincophosphite Framework with Interesting Gas Adsorption and Luminescence Properties

A new 3D tubular zinc phosphite, Zn2(C22H22N8)0.5(HPO3)2⋅H2O (1), incorporating a tetradentate organic ligand was synthesized under hydro(solvo)thermal conditions and structurally characterized by single‐crystal X‐ray diffraction. Compound 1 is the first example of inorganic zincophosphite chains being interlinked through 1,2,4,5‐tetrakis(imidazol‐1‐ylmethyl)benzene to form a tubular porous framework with unusual organic–inorganic hybrid channels. The thermal and chemical stabilities, high capacity for CO2 adsorption compared to that for N2 adsorption, and interesting optical properties of LED devices fabricated using this compound were also studied. Down the tube! A new 3D tubular framework with unusual organic–inorganic hybrid channels was synthesized by incorporating a tetradentate organic ligand, 1,2,4,5‐tetrakis(imidazol‐1‐ylmethyl)benzene, into the structure of an inorganic metal phosphite under hydro(solvo)thermal conditions. The thermal and chemical stabilities, high capacity for CO2 gas adsorption compared to that for N2 adsorption, and interesting luminescence properties of LED devices fabricated using this compound were also studied.
