The research focuses on the synthesis, structure, and luminescent properties of a novel 3D porous metal-organic framework (MOF) with rutile topology, denoted as Cd(CTC)(HPDA)·(H2O) (1). The MOF was synthesized using 1,3-propanediamine (PDA) as a template, with cadmium chloride dihydrate and cis,cis-1,3,5-cyclohexanetricarboxylate (CTC) as reactants. The synthesis involved mixing these compounds in N,N-dimethylformamide, ethylene glycol, and water, followed by the slow diffusion of PDA at 65°C for five days, yielding colorless block-shaped crystals. The product was characterized using X-ray crystallography, which revealed a 3D network with quadrangular channels. The structure was further analyzed using thermogravimetric analysis (TGA), differential thermal analysis (DTA), powder X-ray diffraction (XRD), inductively coupled plasma (ICP) analysis, and infrared (IR) spectroscopy. The compound exhibited intense fluorescence at 364 nm upon excitation at 240 nm at room temperature, indicating potential as a photoactive material. The research was supported by several funding agencies and the crystallographic data was deposited with the Cambridge Crystallographic Data Centre.
