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.

基于N-二苯基膦酰基甲基-3-氨基吡啶的银-氧配合物的组装及其结构，光催化和光电流响应†

合成了一种新的PN杂配体N-二苯基膦基甲基-3-氨基吡啶（3-dppmapy），并使其与包括AgTFA（TFA =三氟乙酸），AgOTF（OTF =三氟甲磺酸），AgNO ₃，Ag ₂ SO的六种银含氧盐反应_在图4中，AgBz（Bz ＝苯甲酸酯）和AgSal（Sal ＝水杨酸酯）。该反应导致两个双核配合物的形成将[Ag ₂（OX）₂（3-dppmapy）₂ ]（1，牛= TFA; 2，牛= OTF）和四个1D配位聚合物的Ag（μ-η ² -NO ₃）（3-dppmapy）·乙醇（3 ·EtOH）中，将[Ag ₂（μ-η，η-SO ₄）（3-dppmapy）₂ ]·氯仿₃（4 ·氯仿₃）和[Ag（μ-η ² -BZ）（3- dppmapy）]（5）和将[Ag（μ-η ² -Sal）（3 -dppmapy）]（6）。所有六个化合物的能带在3.11–3.43 eV之间，处于半导体材料的范围内，而只有6个化合物在紫外线照射下在水溶液中表现出良好的稳定性。在水相中，6在降解铬铁黑T（EBT），酰胺黑（AB）和尼古丁（NO）方面表现出高的光催化性能，并且还显示出相对较快的阳极光电流响应。
