摘要
A novel coordination polymer(CP){[Cd_(2)(L)(1,4-bimb)_(1.5)(DMF)_(2)]·DMF}n(1)(H_(4)L=5,5'-[1,1'-biphenyl-4,4'-diylbis(oxy)]diisophthalic acid,1,4-bimb=1,4-bis(imidazole-1-ylmethyl)-benzene)has been designed and synthesized through solvothermal reaction.Structural analysis shows that Cd(Ⅱ)is connected by H4L and 1,4-bimb to form a 2D network,and 1,4-bimb further expands the 2D network into a 3D framework.CP 1 can be used as an excellent fluorescence sensor for Fe^(3+)and 4-nitrophenol(4-NP),with low detection limits and good anti-interference.The detection limits of Fe^(3+)and 4-NP were 0.034 and 0.031μmol·L^(-1),respectively.In addition,the fluorescence quenching mechanism was studied.1 was successfully applied to determine Fe^(3+)and 4-NP content in the Yanhe River water sample.CCDC:2351092.
采用溶剂热法合成了1例新的配位聚合物(CP){[Cd_(2)(L)(1,4-bimb)_(1.5)(DMF)_(2)]·DMF}_(n)(1),其中H_(4)L=5,5'-(1,1'-联苯基-4,4'-二氧)间苯二甲酸,1,4-bimb=1,4-双(咪唑基-1-甲基)-苯。结构分析表明,H_(4)L和1,4-bimb连接Cd(Ⅱ)形成2D网,1,4-bimb将2D网扩展为3D框架。CP 1可以作为Fe^(3+)和对硝基苯酚(4-NP)的荧光传感器,检出限低,抗干扰性好。检出限分别为0.034和0.031μmol·L^(-1)。此外,还研究了其荧光猝灭机理。成功将1应用于延河水样中Fe^(3+)和4-NP含量的测定。
