Dimeric Organic–Inorganic Hybrid Zr-Substituted Antimonotungstate-Featured Photochromic Responses
Photochromic materials are increasingly attracting attention for their potential applications in smart devices. Here, a novel organic-inorganic hybrid Zr-containing polyoxometalate [H<sub>2</sub>N(CH<sub>3</sub>)<sub>2</sub>]<sub>10</sub>H<sub>8</sub>[Zr(DL-tart)<sub>2</sub>(SbW<sub>17</sub>ZrO<sub>58</sub>)<sub>2</sub>]·36H<sub>2</sub>O (DL-tartH<sub>4</sub> = dl-Tartaric Acid) <b>(1)</b> was synthesized. The dimeric polyanion of <b>1</b> contains two Dawson-like {SbW<sub>17</sub>ZrO<sub>58</sub>}<sup>7-</sup> subunits bridged by one {Zr(DL-tart)<sub>2</sub>}<sup>4-</sup> connector. Interestingly, compound <b>1</b> exhibits a rapid photochromic response with a half-life (<i>t</i><sub>1/2</sub>) of 6.62 s, good reversibility, and an easy fading process in an air environment. Notably, compound <b>1</b> also retains its photochromic behavior upon exposure to visible light irradiation.
