A novel three-dimensional cadmium sulfate-based inorganic-organic hybrid polymer with green photoluminescence.

Layer diffusion of 3,5-bis(4-pyridyl)-1<italic>H</italic>-1,2,4-triazole (BptH) in ethanol on an aqueous solution of cadmium sulfate leads to a novel three-dimensional cadmium sulfate-based inorganic-organic hybrid polymer (IOHP), CdSO4(H2O)(BptH)·1.5H2O (<bold>1</bold>). Its structure was determined by single-crystal X-ray diffraction (SCXRD), and further characterized by elemental analysis, powder X-ray diffraction (PXRD), infrared spectra (IR), and thermogravimetric (TG) analysis. IOHP <bold>1</bold> exhibits a novel 2-nodal 3,5-connected nanoporous structure formed by BptH ligands connecting 2D neutral inorganic cadmium sulfate layers. Water molecules reside in its nanoporous channels. The thermal stability and solid-state photoluminescence properties of the compound have also been investigated. [ABSTRACT FROM AUTHOR]
