Synthesis of diarylenenaphthylene- and diaryleneanthrylene-containing organosilicon polymers and their applications to organic EL devices

Stille coupling reactions of bis(stannylphenyl- and stannylthienyl)silane with dibromonaphthalene and bis(bromothienyl)anthracene gave the corresponding polymers containing naphthylene or anthrylene units in the backbone. Applications of the polymers to electroluminescent (EL) devices were examined and it was found that the diphenyleneanthrylene-containing polymer can be used as a good hole-transporting material in a double-layered EL device.
