光致变色分子是光激活双稳态分子的例子。我们强调了一类钌和锇亚砜配合物的设计标准，这些配合物经过光触发的结合亚砜异构化。这些配合物的作用方式是亚砜从s键到o键的激发态异构化。我们讨论了这种转化的基本机制，并强调了具体的例子，证明了异构化的有效性和效率。我们随后讨论了过渡金属多吡啶配合物上光引发亚砜异构化的未来研究方向。这些努力涉及到新的合成方向，包括金属的选择以及用于异构化的新的双齿配体。
Photochromic molecules are examples of light-activated bistable molecules. We highlight the design criteria for a class of ruthenium and osmium sulfoxide complexes that undergo phototriggered isomerization of the bound sulfoxide. The mode of action in these complexes is an excited-state isomerization of the sulfoxide from S-bonded to O-bonded. We discuss the basic mechanism for this transformation and highlight specific examples that demonstrate the effectiveness and efficiency of the isomerization. We subsequently discuss future research directions within the field of phototriggered sulfoxide isomerizations on transition metal polypyridine complexes. These efforts involve new synthetic directions, including the choice of metal as well as new ambidentate ligands for isomerization.
