“Reversible” photochromism of polyoxomolybdate–viologen hybrids without the need for proton transfer

“Reversible” photochromism of polyoxomolybdate–viologen hybrids without the need for proton transfer

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 ).
