Hemocompatible 3D Silver(I) Coordination Polymers: Synthesis, X-ray Structure, Photo-Catalytic and Antibacterial Activity
Three new Ag(I) coordination polymers, namely, [Ag3(pyp)3
(H2O)2](bpydc)1.5(H2O)6 (1), Ag2(dpe)2(phdac)](H2O)5.4 (2), and
[Ag2(azbpy)3(H2O)2].(dga)(H2O)5 (3) (where pyp=1,3-bis(4-pyridylpropane),
H2bpydc=2,2’-bipyridine-5,5’-dicarboxylic acid,
dpe=1,2-di(4-pyridyl)ethylene, H2phdac=1,4-phenylenediacetic
acid, azpy=4,4’-azobispyridine and H2dga=diglycolic acid)
were synthesized and characterized using elemental analysis,
IR, UV–vis, fluorescence spectroscopy, and single crystal X-ray
diffraction. The most interesting aspect of these coordination
polymers (CPs) in the solid state is represented by the number
of lattice water molecules that, along with carboxylate ligands,
play a crucial role in network formation through H-bonds to
attain a 3D structure. The band gap energies of the CPs were
calculated. Among the compounds studied CP 2 was proved to
be the most efficient photocatalyst for the degradation of
noxious organic dye methylene blue (MB) and in addition
tendered better antibacterial activity. Finally, all three CPs
showed to be hemocompatible
