Synthesis and Fluorescent Properties of a Chiral 2D Tetranuclear Cd(II) Coordination Polymer Based on Asymmetrical Biphenyltetracarboxylate
Solvothermal reaction of Cd(OAc)2·2H2O and biphenyl-2,3,3′,5′-tetracarboxylic acid (H4bptca) in DMF/H2O afforded one novel coordination polymer [Cd4(bptca)2(DMF)4]n (1). X-ray structural analysis reveals that com...
