Abstract

Via the employment of a mixed-ligand method, a novel Pb(II)-coordination polymer with the chemical formula of [Pb(pdc)(bdc)]·2DMF (1, H2bdc = 1,4-benzenedicarboxylic acid and H2pdc = 3,5-pyridinedicarboxylic acid) has been produced via reaction of Pb(NO3)2 with the two organic linkers in a mixed solvent of DMF and water. Complex 1 has high photocatalytic degradation efficiency for methylene blue and rhodamine B under ultraviolet light irradiation. The mechanism of photocatalysis was hypothesized and verified in detail by the r photocatalysis reaction in the existence of the hydroxyl radical scavenger mannitol. Furthermore, the influence of the inflammatory response in the severe burns rats was evaluated. Firstly, the inflammatory response levels were assessed by measuring the content of IL-6 and TNF-α in the plasma after treated with compound. Next, the real time RT-PCR was carried out to determine the signaling pathway of NF-κB relative expression in inflammatory cells.
