Abstract

A new P–N hybrid ligand N-diphenylphosphanylmethyl-3-aminopyridine (3-dppmapy) is synthesized and allowed to react with six silver oxysalts including AgTFA (TFA = trifluoroacetic), AgOTF (OTF = trifluoromethanesulfonic), AgNO3, Ag2SO4, AgBz (Bz = benzoate) and AgSal (Sal = salicylate). The reactions result in the formation of two dinuclear complexes [Ag2(Ox)2(3-dppmapy)2] (1, Ox = TFA; 2, Ox = OTF) and four 1D coordination polymers Ag(μ-η2-NO3)(3-dppmapy)·EtOH (3·EtOH), [Ag2(μ-η,η-SO4)(3-dppmapy)2]·CHCl3 (4·CHCl3), [Ag(μ-η2-Bz)(3-dppmapy)] (5) and [Ag(μ-η2-Sal)(3-dppmapy)] (6). All six compounds have energy bands between 3.11–3.43 eV which is in the range of semiconductive materials, whereas only 6 exhibits good stability in water solution under UV irradiation. In the aqueous phase, 6 exhibits high photocatalytic performance in the degradation of eriochrome black T (EBT), amido black (AB) and nigrosin (NO), and also shows relatively prompt anodic photocurrent responses.
