The light activated ring-opening reaction of the 1,3-cyclohexadiene chromophore finds application in optical control, optical switching, optical memory, light activated molecular machines, photobiology, photochromic materials, and conformation-specific photocatalysts. The development of ultrafast spectroscopic methods and powerful computational methods have accelerated the understanding and facilitated the application of this important chromophore in a wide range of systems. Here we look at the current state of theoretical and experimental understanding for the ring-opening reaction of the isolated cyclohexadiene molecule and the ring-opening reactions of substituted cyclohexadienes, including fulgides, diarylethenes, and provitamin D.
1,3-环已二烯发色团的光致开环反应在光控、光开关、光存储、光激活分子机器、光生物、光致变色材料和构象特异性光催化剂等领域有着广泛的应用。超快光谱方法和强大的计算方法的发展加速了对这一重要发色团在广泛体系中应用的理解，并促进了其应用。在这里，我们着眼于孤立环己二烯分子的开环反应以及取代环己二烯（包括俘精酸酐、二芳基乙烯和维生素 D 前体）的开环反应的理论和实验理解的现状。
