功能和刺激响应性材料的设计是现代材料科学的主要目标之一。这类材料的结构和性能可以通过各种刺激来控制，其中光往往是最有吸引力的选择。光无处不在，是一种温和的能源，其性质可以针对特定的目标进行远程优化，具有很高的时空分辨率。近年来，对分子取向的光控制引起了人们的特别兴趣，因为它具有可重构的光子元件和光-机械能量转换等潜在应用。在这里，我们提出了这一激动人心的研究领域的一些最新例子和新出现的趋势，重点是液晶、液晶聚合物和光致变色有机晶体，我们相信这些材料有助于突出光响应材料在光子学、能量收集和转换等当前和未来的各种高科技应用中的巨大潜力。
The design of functional and stimuli-responsive materials is among the key goals of modern materials science. The structure and properties of such materials can be controlled via various stimuli, among which light is often times the most attractive choice. Light is ubiquitous and a gentle energy source and its properties can be optimized for a specific target remotely, with high spatial and temporal resolution. Light-control over molecular alignment has in recent years attracted particular interest, for potential applications such as reconfigurable photonic elements and optical-to-mechanical energy conversion. Herein, we bring forward some recent examples and emerging trends in this exciting field of research, focusing on liquid crystals, liquid-crystalline polymers and photochromic organic crystals, which we believe serve to highlight the immense potential of light-responsive materials to a wide variety of current and future high-tech applications in photonics, energy harvesting and conversion.
