LIGHT-EMITTING DIODE COMPRISING AN ACTIVE LAYER OF 2,5-SUBSTITUTED POLY(P-PHENYLENE VINYLENE)

A description is given of a LED comprising an active layer of novel, conjugated 2,5-alkyl-substituted poly(p-phenylene vinylene) compounds having a repeating unit (I). Said LED emits green light. In these polymers, R1 represents a C10-C12 alkyl group and R2 represents a C1-C4 alkyl group. These poly...

Zusammenfassung:	A description is given of a LED comprising an active layer of novel, conjugated 2,5-alkyl-substituted poly(p-phenylene vinylene) compounds having a repeating unit (I). Said LED emits green light. In these polymers, R1 represents a C10-C12 alkyl group and R2 represents a C1-C4 alkyl group. These polymers can readily be dissolved in organic solvents, so that an active layer can be manufactured in a simple manner by means of spin coating.
