| description | A supramolecular network [H<sub>4</sub>bdcbpy(NO<sub>3</sub>)<sub>2</sub>·H<sub>2</sub>O] (H<sub>4</sub>bdcbpy = 1,1′-Bis(3,5-dicarboxybenzyl)-4,4′-bipyridinium) (<b>1</b>) was prepared by a zwitterionic viologen carboxylate ligand in hydrothermal synthesis conditions. The as-synthesized (<b>1</b>) has been well characterized by means of single-crystal/powder X-ray diffraction, elemental analysis, thermogravimetric analysis and infrared and UV-vis spectroscopy. This compound possesses a three-dimensional supramolecular structure, formed by the hydrogen bond and π–π interaction between the organic ligands. This compound shows photochromic properties under UV light, as well as vapochromic behavior upon exposure to volatile amines and ammonia, in which the electron transfer from electron-rich parts to the electron-deficient viologen unit gives rise to colored radicals. Moreover, the intensive intermolecular H-bonding networks in <b>1</b> endows it with a proton conductivity of 1.06 × 10<sup>−3</sup> S cm<sup>−1</sup> in water at 90 °C. |
