From 2D→3D interpenetration to packing: N-coligands-driven structural assembly and tuning of luminescent sensing activities towards Fe3+ and Cr2O72- ions

Abstract

Three new luminescent transition coordination polymers, namely, {[Cd(L)(4,4-bpy)]∙DMF∙H2O}n (1), {[Cd2(L)2(bpe)2]∙3DMF∙2.5H2O}n (2), and {[Cd(L)(bibp)]∙2DMF}n (3), (H2L = 4,4'-[benzene-1,3-diylbis(methanediylsulfanediyl)]dibenzoic acid, 4,4-bpy = 4,4-bipyridine, bpe = 1,2-bis(4-pyridyl)ethylene, bibp = 4,4’-bis(benzoimidazo-1-ly)biphenyl), have been solvothermally synthesized through Cd2+ ions and S-containing dicarboxylate acid in the presence of different N-coligands. These complexes were fully characterized by elemental analysis, infrared spectroscopy (IR), single crystal X-ray diffraction analysis, thermal gravimetric analysis (TGA). Complexes 1-3 all consist of 2-D structures through the connectivity of similar 1-D Cd-L chains by different N-coligands. With the increasing size of N-coligands, these complexes show structural changes from 2D→3D 3-fold interpenetration of complexes 1 and 2 to 2-D packing modes of complex 3. The luminescence properties for three complexes have been studied in details. The results reveal that each complex exhibits selectivity and sensitivity towards Fe3+ and Cr2O72- ions in which complex 2 demonstrates the lowest detection limit towards both ions.
