| 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. |
