Abstract

Five kinds of heterofluorenes (silafluorene, oxygafluorene, sulfafluorene, phosphafluorene, carbazole) and 2,5- dihexylbenzene alternative conjugated copolymers have been developed via Suzuki coupling reaction. The successful preparation of the conjugated copolymers opens a door for a new kind of host materials with high triplet state energy as excellent host materials and special optical properties with tremendous potential in the field of organic electronics without the typical defects of polyfluorene.
