Abstract

Ambient temperature solid state reaction of a preformed compound {[Pb(Tab)2]2(PF6)4}n (1) (TabH = 4-(trimethylammonio)benzenethiol) with two equiv. of 1,2-bis(4-pyridyl)ethylene (bpe) quantitatively produces a unique two-dimensional coordination polymer {[Pb(Tab)2(bpe)]2(PF6)4}n (2). The Ag(I)-doped coordination polymer {[Pb(Tab)2(bpe)]2(PF6)4·1.64AgNO3}n (2a) is readily prepared by immersing 2 into AgNO3 aqueous solution. Compared with its two precursors 1 and 2, 2a exhibits greatly enhanced catalytic activity towards the photodegradation of a family of 12 azo dyes within a short period of time under UV light irradiation and excellent adaptability on the elimination of azo dyes in water. It is anticipated that the ‘Ag(I)-doping’ synthetic strategy reported in this work may be applicable to other coordination polymer systems containing thiolate ligands for the preparation of various metal ion-doped multidimensional coordination polymers with new topological structures and better catalytic performances in the photodecomposition of azo dyes in industrial wastewater.
