Abstract
Multifunctional electroactive copolymers are provided. The copolymers may be A-B-A triblock copolymers, brush-type graft copolymers, or variations thereof. In a preferred embodiment, the copolymers are “dual use” in that they comprise both a light emitting segment and a charge transport segment. Methods of synthesizing the novel electroactive copolymers are provided as well, as are opto-electronic devices, particularly LEDs, fabricated with the novel copolymers.
