Two new Cu(II)/Co(II) coordination polymer (CPs) namely, [Co2(H2O)2(L)2(2,2’-bipy)2•H2O] (1) and [Cu2(L)2(bbi)] (2) (H2L=3,3′-(1,2-phenylenebis(methyleneoxy)) dibenzoic acid, bbi = 1,1′-(1,4-butanediyl)bis(imidazole), 2,2,’-bipy=2,2,’-bipyridine), have been designed and synthesized. 1 has 1D helical structure built by the connectivity of Co atoms and phenolic-oxygen containing branches of the flexible
两种新的Cu(II)/ Co(II)配位聚合物(CP),即[Co 2(H 2 O)2(L)2(2,2'-bipy)2 •H 2 O](1)和[ Cu 2(L)2(bbi)](2)(H 2 L = 3,3'-(1,2,亚苯基双(亚甲氧基))二苯甲酸,bbi = 1,1'-(1,4-丁二基)设计并合成了双(咪唑)2,2,'-bipy = 2,2,'-联吡啶。1个通过Co原子与柔性二羧酸酯键的含酚氧分支的连接而构建的1D螺旋结构,通过强大的π•••π堆积相互作用和H键相互作用进一步形成了2D超分子薄片。图2显示了由双[Cu 4 L 2 ]链和反构象bbi配体构成的2D层。目前的结果表明,N-供体配体可能在这些残基的形成中起独特作用。研究了在紫外线照射下降解甲基紫(MV)和若丹明B(Rh B)的光催化性能。
