The importance of a backbone: The mechanism of formation of Dewar lesions has been investigated by using femtosecond IR spectroscopy and ab initio calculations of the exited state. The 4π electrocyclization is rather slow, occurs with an unusual high quantum yield, and--surprisingly--is controlled by the phosphate backbone.
通过飞秒红外光谱和激发态的从头计算研究了 Dewar 损伤的形成机制。4π电环化反应相当缓慢，具有不寻常的高量子产率，而且——令人惊讶的是——受磷酸盐主链控制。
