Abstract
A series of alternating copolymers containing triphenylamine (TPA) moieties
and oligomeric PPV segments in the main chain have been synthesized by Wit
tig condensation. The resulting polymers exhibit good thermal stability wit
h decomposition temperatures (Tds) above 305 degreesC under nitrogen at 10
degreesC/min, and high glass transition temperatures (Tgs). They show inten
se photoluminescence in solution and film. The single-layer electroluminesc
ent device using TAA-PV1 as emissive layer emits green light at 522nm with
a turn-on voltage of 6V and maximum brightness of about 200cd/m(2) at 20V.
