光致变色二芳基乙烯(DAE)是未来分子电子学中最有前途的分子开关系统之一。最近合成了许多衍生物,并报道了其中两类化合物的实验量子产率(QYS)。虽然QY在各种应用中是最重要的性质之一,但在分子实际合成之前,它也是最难预测的性质。我们之前已经报告了关于是什么决定了这两类DAE衍生品的QYS的初步理论研究。在这里,反映了势能面的理论分析和最近的实验结果,合理地解释了QY设计的一般指导原则,为未来的分子设计提供了参考。
Photochromic diarylethenes (DAEs) are among the most promising molecular switching systems for future molecular electronics. Numerous derivatives have been synthesized recently, and experimental quantum yields (QYs) have been reported for two categories of them. Although the QY is one of the most important properties in various applications, it is also the most difficult property to predict before a molecule is actually synthesized. We have previously reported preliminary theoretical studies on what determines the QYs in both categories of DAE derivatives. Here, reflecting theoretical analyses of potential energy surfaces and recent experimental results, a rational explanation of the general guiding principle for QY design is presented for future molecular design.
