Resonance Raman (RR) spectroscopy has been employed to study coordinated phenoxyl radicals (M = Ga, Sc, Fe) which were electrochemically generated in solution by using 1,4,7-triazacyclononane-based ligands containing one, two, or three p-methoxy or p-tert-butyl N-substituted phenolates, i.e., 1,4,7-tris(3,5-di-tert-butyl-2-hydroxybenzyl)-1,4,7-triazacyclononane (3Lbut), 1,4,7-tris(3-tert-butyl-5-m
共振拉曼 (RR) 光谱已被用于研究配位苯氧基自由基 (M = Ga、Sc、Fe),这些自由基是通过使用含有 1、2 或 3 个 p-的 1,4,7-三氮杂环壬烷基配体在溶液中电化学产生的。甲氧基或对叔丁基 N-取代酚盐,即 1,4,7-三(3,5-二-叔丁基-2-羟基苄基)-1,4,7-三氮杂环壬烷 (3Lbut), 1, 4,7-三(3-叔丁基-5-甲氧基-2-羟基苄基)-1,4,7-三氮杂环壬烷 (3Lmet), 1,4-双(3-叔丁基-5-甲氧基-2-羟基苄基)-7-乙基-1,4,7-三氮杂环壬烷(2Lmet)和1-(3-叔丁基-5-甲氧基-2-羟基苄基)-4,7-二甲基-1,4,7-三氮杂环壬烷(1Lmet)。苯氧基发色团振动模式的选择性增强是在与 π → π * 跃迁共振激发时实现的。410 纳米。
