Two Novel Ag(I)-Based Coordination Polymers with N-Donor Polypyridine Ligand for Efficient Degradation of Gentian Violet

Two new Ag(I)-based coordination polymers CPs {[Ag₂(L)₂(Cr₂O₇)]·H₂O} and {[Ag(L)]·(BF₄)· (CH₃CN)_0.5} were successfully obtained by using a N-donor polypyridine ligand L {L = 3-[3,5-bis(pyridin-4-yl)-1,2,4-triazolidin-4-yl]pyridine} and silver ion via the solvothermal conditions, which has been fully characterized. On this basis, a typical organic dye gentian violet was selected for the study of the dye degradation performance of the resulting compounds, and the UV spectra showed that the maximum adsorption value of 85% was reached at 50 min. The results show that this novel organic framework can be used for the degradation of the organic dye gentian violet, providing an ideal solution for the treatment of organic dyes.
