The synthesis of the first example of an azaphenalene-based fused aromatic nitroxide TMAO, [1,1,3,3-tetramethyl-2,3-dihydro-2-azaphenalen-2-yloxyl, (5)], is described. This novel nitroxide possesses some of the structural rigidity of the isoindoline class of nitroxides, as well as some properties akin to TEMPO nitroxides. Additionally, the integral aromatic ring imparts fluorescence that is switched
描述了基于 azaphenalene 的稠合芳香族氮氧化物 TMAO 的第一个例子的合成,[1,1,3,3-四甲基-2,3-二氢-2-azaphenalen-2-yloxyl, (5)]。这种新型氮氧化物具有异二氢吲哚类氮氧化物的一些结构刚性,以及一些类似于 TEMPO 氮氧化物的特性。此外,完整的芳环赋予荧光,通过氮氧化合物的自由基清除反应开启荧光,使其成为聚合物降解的敏感探针。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
