摘要：

(Figure Presented) Increasing the TEMPO! Transition metals are not necessary for oxidative polymerization of 2,7-di-magnesated fluorenes. Oxidation readily occurs by using the commercially available 2,2,6,6-tetramethyl-piperine 1 -oxyl radical (TEMPO) as an oxidant. Polyfluorenes with Mn of up to 9000 gmol-1 can be obtained (see scheme). © 2010 Wiley-VCH Verlag GmbH & Co. KGaA.
