摘要: 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)(ClO4)2]·4CH3CN}n(1)和{[Co(trans-L)2(H2O)2](ClO4)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。 |

Abstract: 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)(ClO4)2]·4CH3CN}n(1) and {[Co(trans-L)2(H2O)2](ClO4)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.
