Abstract
Two novel metal-organic frameworks (MOFs), {Cd(Hpbt)I}n (1) and {Cd(Hpbt)(C2O4)0.5}n (2), have been solvothermally synthesized by the reaction of (H2pbt) (H2pbt = 5′-(pyridin-2-yl)-2H,4′H-3,3′-bi(1,2,4-triazole)) and CdI2. X-ray crystal structural analyses reveal that polymer 1 shows one-dimensional structure and polymer 2 exhibits two-dimensional structure. The structure diversities are due to the addition of oxalic acid on the same synthesis conditions. Oxalic acid acts as a linker connecting the 1D structure of 1 to form 2D structure of 2. Furthermore, the solid luminescent measurements show that polymers 1 and 2 exhibit entirely different fluorescent emission intensities at room temperature.
