oa South African Journal of Chemistry - Pb(II) and Mn(II) supermolecular polymers of bipy and (4-chlorophenyloxy) acetate anions : syntheses, structure and fluorescence properties : research article
Two new supermolecular polymers of the formula [Pb4L8(2,2'-bipy)4] 1 and [MnL2(4,4'-bipy)] 2 [HL = (4-chlorophenyloxy) acetic acid] have been synthesized and characterized by X-ray single crystal diffraction analysis, elemental analysis, fluorescence spectroscopy method and electrochemical analysis. Complex 1 is a multinuclear dimmer in which four Pb ions are linked together by the L ligands. In complex 2, each carboxyl of L bridges two Mn ions to form infinite Mn-O-C-O rods. Both in complex 1 and complex 2, π-π stacking and van der Waals' interactions make the two complexes stable, 3-D, supermolecular polymers. This work will contribute to the design and synthesis of fluorescent, supramolecular polymers.
