Abstract
Two new indium coordination polymers (CPs) with mixed-ligand formulated as {[In(1,4-bda)1.5(phen)]•2H2O}n (In1) and {In(1,4-bda)(2,2′-bipy)Cl}n (In2) (1,4-H2bda = 1,4-benzenedicarboxylic acid; phen = 1,10-phenanthrolin; 2,2′-bipy= 2,2′-bipyridine) have been synthesized and characterized by single-crystal X-ray diffraction, infrared (IR), elemental analysis and thermal gravimetric analyses (TGA). In1 exhibits one-dimensional (1D) ladder chain, which further forms three-dimensional (3D) structure with π⋯π stacking interaction. Formation of 3D compact supramolecular framework in In2 is generated through C-H...Cl hydrogen bonding contacts and π⋯π stacking interaction. The photoluminescence (PL) characterizations to In1 and In2 affected by solvent and temperature are studied in detail. Thermogravimetric curves showed that In1 and In2 start to undergo phase transition until ca. 450°C and 495°C, respectively.
