Paper Abstract

Further routes have been developed for the synthesis of a 1,4-bishalomethylbenzene derivatives for Gilch dehydrohalogenation polycondensation. Poly(2,3-dibutoxy- 1,4-phenylenevinylene) is a protoypical conjugated polymer which is thought to derive its high PL solid state fluorescence efficiency from the sterically twisted backbone and devices carrying this polymer have been further evaluated. Distyrylbenzene derivative carrying the structural feature of a 2,3-dibutoxy substitution pattern on the central ring have been prepared. One in particular has been copolymerized with a 9,9-dialkyl-fluorene-2,7- diboronate ester. The resulting conjugated polymer shows a good green emission maximum in an electroluminescent device.
