Charge-Transfer Complexes of Dinuclear Ruthenium Compounds/ Polyoxometalates for Multistate Electrochromism Covering Ultraviolet, Visible, and Near-infrared Region

Abstract

A series of novel charge-transfer electrostatic omplexes between the anionic polyoxometalates and cationic dinuclear ruthenium compounds have been prepared. The inter-molecular charge transfer from the electron-donor MCH-Ru to the electron-acceptor PMo12 occurs to generate the mixed-valence species of RuII/RuIII and MoVI/MoV in the complex, and consequently complementation of their corresponding charge-transfer absorption bands can obtain the full spectrum covering ultraviolet, visible, and near-infrared region in its ground state with no need for external stimuli. Diverse polyoxometalates with various structures and charge densities were invsetigated and results show that both of the energy matching and molecular structures play the important roles in the charge transfer process. Amphiphilic dinuclear ruthenium molecules enable their corresponding complexes to form the supramolecular assemblies, morphologies of which also correlate to the efficency of charge transfer. Besides, smart ternary memories have been realized by using the thus-prepared complexes with three electrochemical inputs and three optical outputs, and the hybrid complexes are promising for applications in multistate electrochromic materials and devices with tunable photoelectric properties.
