Novel 3‐D Supramolecular Architectures Constructed from Zn2+ ions, Oxybis(4‐benzoate) and Di(2‐pyridyl)amine Ligands

Novel 3‐D Supramolecular Architectures Constructed from Zn2+ ions, Oxybis(4‐benzoate) and... Using the V‐shaped oba dianions as bridging ligands and dpa molecules as terminal ligands, a new 1D helical coordination‐polymeric chain, [Zn(oba)(dpa)]n [oba=oxybis(4‐benzoate), dpa=di(2‐pyridyl)amine], was synthesized and characterized by single‐crystal X‐ray diffraction, elemental analyses, UV‐Vis and IR spectra, and TGA analysis. X‐ray structural analysis revealed that, oba and dpa ligands played an important role in the self‐assembly of the helical chains by providing potential supramolecular recognition sites for π‐ π aromatic stacking and hydrogen‐bond interactions, resulting in the self‐assembly of the (4,4) networks to give a 3‐D supramolecular framework.

Abstract

Using the V‐shaped oba dianions as bridging ligands and dpa molecules as terminal ligands, a new 1D helical coordination‐polymeric chain, [Zn(oba)(dpa)]n [oba=oxybis(4‐benzoate), dpa=di(2‐pyridyl)amine], was synthesized and characterized by single‐crystal X‐ray diffraction, elemental analyses, UV‐Vis and IR spectra, and TGA analysis. X‐ray structural analysis revealed that, oba and dpa ligands played an important role in the self‐assembly of the helical chains by providing potential supramolecular recognition sites for π‐ π aromatic stacking and hydrogen‐bond interactions, resulting in the self‐assembly of the (4,4) networks to give a 3‐D supramolecular framework. The photoluminescence properties of the title compound were also investigated, showing intense blue photoluminescence properties at room temperature.
