Synthesis, Structural Characterization and Fluorescent Property of Cd(II) Coordination Polymer Containing Pyridinium Zwitterionic Ligand

A novel Cd(II) Coordination Polymer, [Cd(L)(2)(SO4)(2)(H2O)(2)][Cd(H2O)(6)]& BULL;4H(2)O (CP 1) (L = (1,1'-((2,3,5,6-tetramethyl-1,4-phenylene)bis(methylene))bis(4-carboxypyridin-1-ium)chloride)), is prepared and characterized by single-crystal X-ray diffraction, elemental analysis, powder X-ray diffraction, infrared spectrum, thermogravimetric analysis, solid-state fluorescence properties and CIE analysis. The single-crystal X-ray diffraction studies reveal that the ligand HLClO4 center dot H2O crystallizes in the monoclinic P2(1)/n space group, while CP 1 crystallized in the triclinic P-1 space group with two distinct Cd(II) centers. Abundant hydrogen bonds produce the 3D supramolecular structure of CP 1. The experimental results show that the CP 1 has good thermal stability and has potential applications in blue luminescent materials.{GRAPHICAL ABSTRACT}
