A novel tubular coordination network [Zn(spcp)(OH)](spcp=4-sulfanylmethyl-4'-phenylcarboxylate pyridine) with a modest SHG activity based on two types of homo-chiral helices was synthesized and characterized.
Crystal engineering based on noncentrosymmetric metal–organic frameworks (MOFs) by using asymmetric bridging ligands as building blocks has attracted much attention owing to its potential applications as second-order nonlinear optical (NLO) materials.The utilization of asymmetric bridging ligands can introduce electronic asymmetry (push–pull effect),which is essential for a second harmonic generation (SHG) response.At present,there are numerous examples with three dimensional interpenetrated diamondoid or two-dimensional grid structural motifs assembled by combining unsymmetrical,rigid,and linear pyridinecarboxylate ligands and d10 metal ions (in particular Zn2+ and Cd2+) for their favorable optical transparency.However,the helical and other recurring coordination
networks used in NLO materials still remain few explored.Widely found in nature,helical structural motifs exhibit axial chirality,and can crystallize in noncentrosymmetric space groups.We believe that the introduction of chemical interaction sites in asymmetric bridging ligands is a challenging subject in developing new polar and chiral systems,and aesthetic structural motif with fascinating functions can be obtained.
