Abstract

Two new coordination polymers based on 4-[(8-hydroxy-5-quinolinyl)azo]-benzenesulfonic acid(H2L), {[CdL(H2O)2]·H2O}n(1) and {[CdL(en)]·EtOH}n(2)(en=ethylenediamine), were solvothermally synthesized and structurally characterized by single-crystal X-ray diffraction. Compounds 1 and 2 exhibit infinite 1D ladder-shaped chain structures, which are isostructural except that the two coordinating water molecules in compound 1 were replaced by one en molecule in compound 2 due to the use of different organic base. Compounds 1 and 2 were constructed into different supramolecular frameworks by hydrogen bonding and π...π stacking interactions. In addition, the fluorescent properties of compounds 1 and 2 were investigated. Furthermore, they were also investigated via IR spectral analysis, elemental analysis, powder X-ray diffraction(PXRD) and thermogravimetric analysis(TGA).
