Polymers containing 9,10-phenanthraquinone moieties as part of an extended π-electron system have been prepared by Suzuki couplings between 2,7- or 3,6-dibromophenanthraquinone and 9,9-dioctylfluorene-2,7-diboronic acid bispinacol ester. Closely related model compounds were prepared similarly. All the products were characterised by FT-IR, 1H NMR and UV-vis/fluorescence spectroscopy and, where relevant, mass spectrometry. Cyclic voltammetry measurements indicate that these materials display electron affinities of up to 4.0 eV. This value is one of the highest reported for conjugated polymers.
含有 9,10-菲醌部分作为扩展 π-电子系统一部分的聚合物已通过 2,7-或 3,6-二溴菲醌与 9,9-二辛基芴-2,7-二硼酸双菠哪醇酯之间的 Suzuki 偶联制备。类似地制备密切相关的模型化合物。所有产品均通过 FT-IR、1H NMR 和 UV-vis/荧光光谱以及相关的质谱进行表征。循环伏安法测量表明这些材料的电子亲和势高达 4.0 eV。该值是共轭聚合物报道的最高值之一。
