AgNO 3与四膦配体1，4-N，N，N′，N′-四（二苯基膦甲基）苯二胺（dpppda）反应，得到Ag（I）/四膦配位聚合物[Ag 4（NO3）4（dpppda）]n（1）。化合物1具有一维（1D）链结构，其中椅状[Ag 4（NO3）4]核通过dpppda配体以Z形μ-η2：η 2并排模式连接。化合物1在紫外光照射下对硝基苯（NB）、对硝基苯酚（PNP）和2，4-二硝基苯酚（2，4-DNP）具有良好的光催化活性。并对该催化光降解反应的动力学和机理进行了研究。本工作为设计和制备新型配位聚合物催化剂高效光降解工业废水中的有毒持久性有机物提供了新的思路。
Reaction of AgNO3with one tetraphosphine ligand, 1,4-N,N,N′,N′-tetra(diphenylphosphanylmethyl) benzene diamine (dpppda), gave rise to a Ag(I)/tetraphosphine coordination polymer [Ag4(NO3)4(dpppda)]n(1). Compound1has a one-dimensional (1D) chain structure in which the chair-like [Ag4(NO3)4] cores are linked by the dpppda ligands using a Z-shapedμ-η2:η2side-by-side mode. Compound1exhibited good catalytic activity towards the photodegradation of nitrobenzene (NB), paranitrophenol (PNP) and 2,4-dinitrophenol (2,4-DNP) in aqueous solution under UV light irradiation. The kinetics and the mechanism of such catalytic photodegradation reactions were also investigated. The present work provided some new insight into the design and preparation of new coordination polymers as catalyst for high-performance photodegradation of toxic and persistent organic species existed in industrial wastewaters.
