Abstract

Abstract : The "reversible" photochromism of polyoxomolybdate–viologen hybrids can be achieved without proton transfer, and the weak electron-withdrawing ability of viologen favors photoreduction of Mo(vi ). Abstract : A case study of two new covalently bonded polyoxomolybdate–viologen hybrids revealed that "reversible" photochromic properties can be achieved without the need for proton transfer, and the weak electron-withdrawing ability of the coordinated ligand favors photoreduction of Mo(vi ) to Mo(v ).
