Abstract

Photochromic materials are increasingly attracting attention for their potential applications in smart devices. Here, a novel organic–inorganic hybrid Zr-containing polyoxometalate [H₂N(CH₃)₂]₁₀H₈[Zr(DL-tart)₂(SbW₁₇ZrO₅₈)₂]·36H₂O (DL-tartH₄ = dl-Tartaric Acid) (1) was synthesized. The dimeric polyanion of 1 contains two Dawson-like {SbW₁₇ZrO₅₈}^7– subunits bridged by one {Zr(DL-tart)₂}^4– connector. Interestingly, compound 1 exhibits a rapid photochromic response with a half-life (t_1/2) of 6.62 s, good reversibility, and an easy fading process in an air environment. Notably, compound 1 also retains its photochromic behavior upon exposure to visible light irradiation.

二聚体有机-无机杂化锆取代反单钨酸盐的光致变色反应

光致变色材料因其在智能设备中的潜在应用而越来越受到人们的关注。本文合成了一种新型的含锆多金属氧酸盐[H2N(CH3)2]10H8[Zr(DL-tart)2(SbW17ZrO58)2]·36H2O （DL-tartH4 = dl-酒石酸）(1)。二聚体聚阴离子1含有两个类似于道森的{SbW17ZrO58}7 -亚基，由一个{Zr(DL-tart)2}4 -连接连接。有趣的是，化合物1表现出快速的光致变色反应，半衰期（t1/2）为6.62 s，可逆性好，在空气环境中容易褪色。值得注意的是，化合物1在暴露于可见光照射下也保持其光致变色行为。
