AbstractA new two-dimensional ZnII coordination framework [Zn(1,3-BMIB) (OBA)]n (1) (where H2OBA is 4,4ʹ-oxy-bis(benzoic acid) and 1,3-BMIB is 1,3-bis(2-methyl-1-imidazolyl)benzene) has been prepared and characterized through IR spectroscopy, elemental and thermal analysis, and single-crystal X-ray diffraction. Complex 1 is a (4, 4) grid coordination polymer with a layer structure. It exhibits high photocatalytic degradation effects upon UV irradiation of methylene blue and methylene orange aqueous solutions.

The synthesis is reported of the tricarboxylic acid 3-(3,5-dicarboxybenzyloxy)benzoic acid (H3L) and the product of its reaction under solvothermal conditions with ZnIIcations, namely poly[[μ6-3-(3,5-dicarboxylatobenzyloxy)benzoato](dimethylformamide)-μ3-hydroxido-dizinc(II)], [Zn2(C16H9O7)(OH)(C3H7NO)]n, the formation of which is associated with complete deprotonation of H3L. Its crystal structure consists of a single-framework coordination polymer of the organicL3−ligand with ZnIIcations in a 1:2 ratio, with additional hydroxide and dimethylformamide (DMF) ligands coordinated to the ZnIIcentres. The ZnIIcations are characterized by coordination numbers of 5 and 6, being bridged to each other by hydroxide ligands. In the polymeric framework, the carboxylate- and hydroxy-bridged ZnIIcations are arranged in coordination-tessellated columns, which propagate along theaaxis of the crystal structure, and eachL3−ligand links to seven different ZnIIcentresviaZn—O bonds of two different columns. The coordination framework, composed of [Zn2(L)(OH)(DMF)]nunits, forms an open architecture, the channel voids within it being filled by the zinc-coordinating DMF ligands. This report provides the first structural evidence for the formation of coordination polymers with H3L viamultiple metal–ligand bonds through its carboxylate groups.<!?tpb=21.5pt>

Tem Characterization

An optical waveguide consists of a several-micron wide channel with a slightly different index of refraction than the host substrate; light can be trapped in the channel by total internal reflection.Optical waveguides can be formed from single-crystal LiNbO3 using the proton exhange technique. In this technique, polished specimens are masked with polycrystal1ine chromium in such a way as to leave 3-13 μm wide channels. These are held in benzoic acid at 249°C for 5 minutes allowing protons to exchange for lithium ions within the channels causing an increase in the refractive index of the channel and creating the waveguide. Unfortunately, optical measurements often reveal a loss in waveguiding ability up to several weeks after exchange.
