Photocleavage of the NO bond of N-(9-anthroyloxy)-9-fluorenylideneamine takes place efficiently in acetonitrile in the excited singlet state attributed to the fluorenylidene moiety. This made it possible for the first time to directly observe 9-anthroyloxyl radicals. However, the efficiency decreases remarkably in benzene in which the lowest excited singlet state is attributed to the anthroate moiety

亚胺的N = O键的光裂解在
乙腈中有效地发生,归因于
芴叉基部分的激发单重态。这使第一次有可能直接观察到9-
蒽氧基基团。然而,在苯中,效率最低的是苯,其中最低的激发单重态归因于
邻苯二甲酸酯部分。
