摘      要：A novel metalloviologen complex{[Cd(PhSQ)(HTBC)(H_(2)O)_(2)]·1.25 H_(2)O}n(1)based on N-(4-sulfophenyl)-4,4’-bipyridinium(PhSQ)and monoprotonated trimesic acid(HTBC)has been prepared and structurally *** 1 has been characterized by elemental analysis,IR,thermogravimetric analyses,UV-Vis spectra and X-ray *** coordination geometry of Cd(Ⅱ)ion is a pentagonal *** 1 displays a zigzag chain along the b axis,and such chains are extended into a 2 D layer supramolecular network through hydrogen bonding and π…π ***,complex 1 exhibits reversible photochromic and switchable luminescent behaviors via UV light irradiation at room temperature induced by the photogenerated radicals via a photo-induced electron transfer(PET)mechanism.
