Abstract:

A porous coordination polymer Zn(4-bpft)(1,4-bdc)](CP 1) was constructed from the N,N′-bis(4-pyridine formamide)-3,4-thiophene(4-bpft) and terephthalic acid (1,4-H2bdc) mixed-ligand under hydrothermal condition. It’s structure and composition were characterized by means of single crystal X-ray diffraction, FTIR and PXRD techniques. The results show that CP 1 is a 2D network with 17.3% of solvent accessible void space by PLATON, which exhibits a 3-connected network with {63} topology. CP 1 displays obvious fluorescent turning on sensing and can efficiently detect asparticacid(Asp). It also exhibits electrochemically reversible redox behavior, and can be used as an amperometric sensor for detecting ascorbic acid(AA). In addition, the adsorption behavior of CP 1 was evaluated with organic dyes methylene blue(MB), gentian purple(GV), and neutral red(NR), implying it has potential application value in removing organic pollutants.
