Abstract: A three-dimensional (3D) porous Zn(Ⅱ)-based framework, {[Zn4(O-BTC)2(H2O)5]·2DMF·0.5H2O}n (1), which is constructed from a multifunctional tricarboxylate ligand, 2-hydroxyl-1,3,5-benzenetricarboxylic acid (HO-H3BTC) and Zn(Ⅱ) salts was prepared. Complex 1 has been characterized by X-ray single-crystal diffraction, PXRD, elemental analysis, infrared spectroscopy, thermogravimetric analysis, and solid-state UV-Vis absorption spectra. Complex 1 exhibits a three-dimensional (3D) framework structure based on the rod-shaped Zn-carboxylate/hydroxyl secondary building unit (SBU). Solid-state luminescence studies showed that 1 exhibits intense blue emission at room temperature. Interestingly, 1 could exhibit afterglow property only under low temperature (10 K) condition.
