Synthesis, structure, and photoluminescence properties of coordination polymers of 4,4′,4′′,4′′′-tetrakiscarboxyphenylsilane and 3,5-bis(1′,2′,4′-triazol-1′-yl)pyridine

摘要: Three coordination polymers (CPs) incorporating both 4,4′,4′′,4′′′-tetrakiscarboxyphenylsilane (H4tcps) and 3,5-bis(1′,2′,4′-triazol-1′-yl)pyridine (btap), namely [Co2(tcps)(btap)(H2O)3] (1), [Co3(Htcps)2(btap)(H2O)6] (2) [Cd3(Htcps)2(btap)(H2O)6] (3), were synthesized by a solvothermal method. Compound 1 features 3D (3,4,5)-connected framework with the (6·75·84)(64·82)(72·9) topology. Compounds 2 3 are isostructural, which display an unusual 1D + → polythreaded supramolecular architecture chain inserted into channels of two-fold interpenetrating motif. Hydrogen bonds among anionic motif cationic further stabilize compounds. The structure compounds is 3-connected point symbol (103)4. luminescence properties compound in their solid state as dispersed various solvents investigated. Luminescence studies have revealed that exhibits high sensitivity stable anti-interference towards Fe3+ Cu2+ cations aqueous solution.
