| 摘要: 本文报道了5种基于蒽和芘配体[1，6-二(1H-咪唑-1-基)芘(dip)和9,10-二(1H-咪唑-1-基)蒽(dia)]和阴离子配体[环己烷-1,4-二羧酸(H2cda)和樟脑酸(H2cpa)]的配位聚合物。在{[Cd (dip)(cda)]·4H2O}n (1)中，Cd2+离子作为四面体节点，通过dip和cda2-配体与4个Cd2+离子连接形成五重相互穿插的网络，为dia拓扑结构。在{[Cd (dip)(cpa)]·4H2O}n (2)中，Cd2+离子作为4-连接体，通过cpa2-和dip配体连接到cds拓扑结构的3D框架中。在{[Ni (dia)2Cl2]·DMF}n (3)中，Ni2+离子被4个dia配体连接成层状结构，形成了横截面为1.35 nm×0.96 nm的1D通道。在{[Cd (dia)2(H2O)2](NO3)2·2DMSO}n (4)中，dia配体将Cd2+离子连接成二维层，相邻层之间形成一维通道，横截面为0.87 nm×0.43 nm。在[Zn (dip) Cl2]n (5)中，Zn2+原子通过dip配体连接成无限一维链。收集并分析了这些配位聚合物的红外、热重和荧光发射数据。 |

| Abstract: We report five coordination polymers (CPs) based on fluorescent ligands [1,6-di(1H-imidazol-1-yl)pyrene (dip), 9,10-di(1H-imidazol-1-yl)anthracene (dia)] and anionic ligands [cyclohexane-1,4-dicarboxylic acid (H2cda), camphoric acid (H2cpa)]. In [Cd(dip)(cda)]·4H2O}n (1), the Cd2+ ions, acting as tetrahedral nodes, are linked by dip and cda2- ligands with four Cd2+ ions into five-fold interpenetrating network array of topology of dia. In {[Cd(dip) (cpa)]·4H2O}n (2), the Cd2+ ions, acting as a 4-connector, are linked by cpa2- and dip ligands into a 3D framework of cds topology. In {[Ni(dia)2Cl2]·DMF}n (3), the Ni2+ ion is linked by four dia ligands into a layer structure, and 1D channels of a cross-section of 1.35 nm×0.96 nm are formed. In {[Cd(dia)2(H2O)2](NO3)2·2DMSO}n (4), the dia ligands connected Cd2+ ions into a 2D layer, and 1D channels are formed between adjacent layers with a cross-section of 0.87 nm×0.43 nm. In [Zn(dip)Cl2]n (5), the Zn2+ ion is linked by dip ligands into an infinite 1D chain. The infrared, thermal gravimetric, and fluorescent emission data were collected and analyzed for these coordination polymers. |
