Abstract : New multifunctional monomers and copolymers and/or composites incorporating these monomer subunits have been synthesized and characterized for applications as third-order nonlinear optical materials or as light-emitting diodes. The chromophore units in the copolymer formulations are related to oligomeric segments of such fully conjugated polymers as poly(P-PHENYLENE VINYLENE), poly2,5-THIENYLENE VINYLENE, polythiophene and diphenylaminodiphenylpolyenes. The copolymers could be fabricated into thin-film light-emitting diodes with emission in the blue region of the visible spectrum. These devices exhibit low turn-on voltages and bright emission and are being considered for commercialization.
