“…Polyoxometalate (POM) is an important branch of the inorganic field, which is a kind of metal oxygen clusters formed by oxygen connection of pretransition metal ions. − Until now, POM has been widely studied as a functional component and applied in many fields such as light, electricity, and magnetism. − Moreover, the surface of POMs is rich in electrons, which can provide electrons easily. Thus, POMs own excellent redox properties, inducing the applications in electrochemistry and catalysis. − Furthermore, the characteristics of rich electrons of POMs can conduce electron transition, which makes POMs act as precursors of chromic materials . Thus, the electron-rich property of POMs and electron-deficient property of viologen can be combined to construct hybrid compounds, in which electron-donor (POMs) and electron-acceptor (viologen) systems are formed to realize electron transfer.…”

A combination of polyoxometalates and viologens to construct discoloration materials with charge transfer has become attractive presently. In this work, four kinds of POM–viologen color-changing materials were successfully synthesized, namely, [Cu(1,4-Mbby)2(HPMoVI 10MoV 2O40)] (1), [H2(1,4-Mbby)2]·(SiMo12O40) (2, 1,4-Mbby·Cl = (1-(4-methyl-benzyl)-[4,4’]bipyridinyl-1-ium)chloridate), [H2(Bypy)2]·(SiMo12O40) (3), and [H(Bypy)]·(Bypy-2)1/2·(PMo12O40) (4, Bypy = 1-benzyl-4,4′-bipyridyinium chloride, Bypy-2 = 1,1′-dibenzyl-4,4′-bipyridine chloride). In compound 1, a [Cu(1,4-Mbby)2]4+ subunit caps on the Keggin anion to build a monosupporting cluster. Compounds 2–4 are discrete structures with dissociative POMs and viologens. All compounds 1–4 show good reversible photochromic properties under xenon lamp (300–400 nm) irradiation. Under the stimulation of current, compounds 1–4 also show reversible electrochromic properties within a certain range of applied voltage. The good color-changing properties of these compounds are due to the generation of free viologen radicals and charge transfer. Based on their color-changing properties, they can be applied to many fields, such as ultraviolet detectors, inkless printing, and visual detection of heavy metal ions. These practical applications are of positive significance for life and production.
