Suzuki coupling modified by adding Ag 2 O instead of the Na 2 CO 3 used in the original reaction protocol, was used as a synthetic tool for the synthesis of a copolymer in which 9,9‐dialkylfluorene moieties were coupled to unsubstituted poly( p ‐phenylenevinylene) (PPV) units. The possibility of performing the polymerisations at moderate temperatures appears to be an advantage related to the use of Ag 2 O. The copolymer shows a M w of 21 000 and M w / M n = 2.1 and is suitable for the construction of electroluminescent devices. Monolayer organic light‐emitting diodes (OLEDs) have been built which emit greenish light.Synthesis of poly(fluorenevinylene‐ co ‐phenylenevinylene).
