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

A new 3D tubular zinc phosphite, Zn-2(C22H22N8)(0.5)(HPO3)(2)center dot 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-tet-rakis(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 N-2 adsorption, and interesting optical properties of LED devices fabricated using this compound were also studied.
