基于偶氮联吡啶配体的银和钴配位聚合物的构筑与性质（英文）

Structures of Silver and Cobalt Coordination Polymers Constructed with Azo-Bipyridine Ligand

通过将2个4,4′-联吡啶基团用偶氮基团连接,我们合成了新的配体顺式-和反式-1,2-二((4,4′-联吡啶)-3-氮烯)(cis-L和trans-L),并利用trans-L与银离子和钴离子构筑了配位聚合物{[Ag2(trans-L)(Cl O4)2]·4CH3CN}n(1)和{[Co(trans-L)2(H2O)2](Cl O4)2}n(2)。其中1为一维梯形链,链与链之间通过π-π以及Ag…Ag相互作用堆积;2为三维无限dendrimer结构,其Co中心具有合适的氧化还原电位,在以荧光素为光敏剂的条件下,可作为光催化剂实现光解水放氢。

By linking two 4,4′-pyridine groups through an azo linker,ligand trans-and cis-1,2-di（（4,4′-bipyridine）-3-yl）diazene（trans-and cis-L） were obtained.And the syntheses of two silver and cobalt complexes {[Ag2（trans-L）（Cl O4）2]·4CH3CN}n（1） and {[Co（trans-L）2（H2O）2]（Cl O4）2}n（2） with the trans-form ligand are reported respectively.The complexes exhibited diverse structure features.And the application of Co complex as a photocatalyst was showed on the light driven hydrogen evolution.
