摘要: 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 similarly. All the products characterised FT-IR, 1H NMR UV-vis/fluorescence spectroscopy and, where relevant, mass spectrometry. Cyclic voltammetry measurements indicate that these materials display electron affinities up to 4.0 eV. This value is one highest reported for conjugated polymers.
