carbazolyl derivatives with a pendant stable radical of the TTM (tris-2,4,6-trichlorophenylmethyl radical) series are reported. The EPR spectra, electrochemical properties, absorption spectra, and luminescent properties of these radical adducts have been studied. All of them show electrochemical amphotericity being reduced and oxidized to their corresponding stable charged species. The luminescence properties
报道了具有TTM侧基稳定基团(tris-2,4,6-三氯苯基甲基基团)的新咔唑基衍生物的合成和表征。已研究了这些自由基加合物的EPR光谱,电化学性质,吸收光谱和发光性质。它们均显示出电化学两性被还原并氧化成其相应的稳定带电物质。它们的发光特性覆盖了发射的红色光谱带。富电子咔唑加合物的发光显示出激发态的施主-受主性质。另一方面,这些自由基加合物的EPR参数显示出咔唑中的取代基有不明显的变化。
