Molecular systems encompassing more than one photochromic entity can be used to build highly functional materials, thanks to their potential multi-addressability and/or multi-response properties. Over the last decade, the synthesis and spectroscopic and kinetic characterisation as well as the modeling of a wide range of multiphotochromes have been achieved in a field that is emerging as a distinct branch of photochemistry. In this review, we provide an overview of the available multiphotochromic compounds which use a variety of photoactive building blocks, e.g., diarylethene, azobenzene, spiropyran, naphthopyran or fulgimide derivatives. Their efficiency in terms of multi-responsiveness is discussed and several strategies to circumvent the most common limitation (i.e., the loss of photochromism of one part) are described.
包含不止一个光致变色实体的分子体系可以用于构建具有高功能的材料,这要归功于它们潜在的多寻址性和/或多响应特性。在过去的十年中,在一个新兴的光化学分支领域中,已经实现了广泛的多光致变色体的合成、光谱和动力学特性以及建模。在这篇综述中,我们提供了可用的多光致变色化合物的概述,这些化合物使用各种光活性构建块,例如二芳基乙烯、偶氮苯、螺吡喃、萘并吡喃或俘精酸酐衍生物。讨论了它们在多响应性方面的效率,并描述了几种克服最常见限制(即一部分光致变色性的丧失)的策略。
