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 M n of up to 9000 g mol −1 can be obtained (see scheme).
