“…The viologen compounds are 4,4′-bipyridine derivatives. First of all, viologen has abundant coordination modes and strong coordination ability, which conduce to link with transition metals . Moreover, viologen molecules are good electron acceptors. − The unique electron-deficient character of viologen photochromic compounds can provide a good path for photoinduced electron transfer. − Therefore, viologen is a good choice as a functional component of color-changing materials.…”

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.

The simultaneous modulation effect of N-substituents on the photochromic and electrochromic properties of naphthalenediimide-based coordination polymers

Abstract: The controllability of the properties of stimuli-responsive chromic materials (SRCM) is of great significance for their practical application. Two two-dimensional (2D) layered coordination polymers (CPs), [Mn(CMNDI)(H2O)2] (1) and [Mn(CENDI)(H2O)2] (2)...
