摘　　要：光作用作为刺激源具有非直接接触、远程控制、快捷等突出优点,使得可逆光致变色材料在信息存储、显示器件和智能窗户等领域有着广泛的应用前景。然而,大多数传统可逆光致变色材料普遍存在热稳定性差、循环寿命低、变色速度慢等问题,严重制约了其在相关领域的发展。近年来,基于半导体纳米颗粒/氧化还原类染料可逆光致变色体系由于将半导体纳米颗粒优异的光催化还原性能和氧化还原类染料独特的变色性质结合于一体,表现出优异的可逆光致变色性能,受到广泛关注,并在无墨“光打印”可擦重写纸、可视化氧气指示器及智能变色织物等领域展现出巨大的应用价值。从半导体纳米颗粒/染料可逆光致变色设计原理、性能和机理研究进展及应用领域等方面进行综述,并提出未来研究展望。Owing to that light as an external stimulus has great advantages of non-invasive,remotely controlled and rapidly changed,photoreversible color switching materials have important applications in data storage,color display,smart windows,anti-counterfeiting and so forth.However,most of the transitional photoreversible color switching materials have problems such as poor thermal stability,low cycling performance,and slow color switching rate,which seriously restricts their developments in related fields.In recent years,the photoreversible color switching systems based on semiconductor nanomaterials/redox dyes have attracted great attentions and exhibited excellent photoreversible color switching properties because the photoreversible color switching systems integrate the outstanding photoreductive activity of semiconductor nanomaterials and the unique redox-driven color switching property of redox dyes.The photoreversible color switching systems show great potential in the applications of inkless,light-printable rewritable paper,colorimetric oxygen indicators,smart color changing textile,and high-level anti-counterfeiting.In this review,the recent progress in design principle,property and mechanism,and application of semiconductor nanomaterials/redox dyes based photoreversible color switching systems are summarized.Furthermore,the future opportunities of this field are prospected.
