Abstract
A luminescent Pr3+-coordination polymer based on functional linear tetrazole-carboxylic acid and an auxiliary ligand, {[Pr(TBCA)(BPA)·2H2O]}n (1) (HTBCA = 4′-(1H-tetrazol-5-yl)-biphenyl-4-carboxylic acid, H2BPA = 2,2′-biphenyldicarboxylic acid), has been solvothermally synthesized and characterized by single crystal XRD, infrared spectroscopy, elemental analysis, and powder X-ray diffraction. Structural analysis reveals that 1 is a 1D coordination polymer with chains approximately parallel to the a-axis, linked by H-bonding interactions to form a 3-D arrangement. The uptake results for six dyes with different size and different charges revealed that 1 can adsorb neutral red and hardly adsorb the other dyes.
