Poly(9,9‐dioctylfluorene) (PFO) with M n values above 100 000 g mol −1 in a toluene/water system and M n values up to 600 000 g mol −1 in a THF/water system has been obtained by improved Suzuki polycondensation using a new kind of amphipathic palladium catalyst with self‐phase‐transfer features, which could overcome the disadvantage caused by the immiscible biphasic mixture and accelerate the transmetalation step (see figure).
