1,3-, 1,6-, 2,6-, and 2,7-naphthoquinodimethane have been obtained by photolysis (254 nm) of bis(chloromethyl)naphthalenes in glassy media at 77 K or in solution at ambient temperature by KrF (249 nm) laser flash photolysis. These species are detected and characterized by fluorescence spectroscopy.
1,3-、1,6-、2,6- 和 2,7-萘并醌二甲烷是通过双(氯甲基)萘在 77 K 的玻璃介质中或在环境温度下的溶液中通过 KrF 光解 (254 nm) 获得的(249 nm) 激光闪光光解。这些物种通过荧光光谱检测和表征。
