“…In recent years, coordination polymers (CPs), as new porous materials constructed by metal ions and organic ligands, have attracted extensive attention due to their exciting and versatile structures. Because of their unique channels and structural features, CPs have rich potential applications in many elds, such as catalysis [1][2][3], magnetism [4][5][6], gas adsorption [7][8][9][10], gas separation [11,12], uorescence [13][14][15] and so on [16][17][18][19][20]. It is well known that most ligands used for the construction of CPs are neutral ligands; however, the synthesis of CPs from pyridinium zwitterionic ligands with separate charges is relatively rare.…”

With pyridinium zwitterionic ligand H 2 LCl 2 (1,1'- ((2,3,5,6-tetramethyl-1,4-phenylene)bis(methylene))bis(4carboxypyridin-1-ium)chloride) as the main connection point, a novel Cd ( ) coordination polymer namely) and a partially deprotonated HLClO 4 •H 2 O were obtained by room temperature volatilization method. X-ray diffraction studies reveal that HLClO 4 •H 2 O crystallizes in the monoclinic P2 1 /n space group, with a bowl shape partially deprotonated HL + cation as the main structure, and the ClO 4 anion which balances the charge just exists outside. When the ligand reacts with CdSO 4 8/3H 2 O, CP 1 crystallized in the triclinic P-1 space group with two distinct Cd ( ) centers was obtained. Abundant hydrogen bonds produce the 3D supramolecular structure of CP 1. Elemental analysis, powder X-ray diffraction, infrared spectrum, thermogravimetric analysis, solid-state uorescence properties and CIE analysis of CP 1 were studied. Results indicate that the CP 1 has good thermal stability and has potential applications in blue luminescent materials.
