摘要： An electroluminescent polymer comprises a main chain and a plurality of side chains, each of the side chains comprising an electroluminescent group and a flexible spacer connecting the electroluminescent group to the main chain, the spacers and the main chain being such that the electroluminescent groups are not conjugated with one another. The nature of the main chain and the spacer groups can be varied to enhance solubility, film-forming ability and other characteristics of the polymer, without significantly changing the electroluminescent properties of the polymer.

摘要： Electroluminescent devices have, as the active layer, a polymer having a chain comprising a plurality of electroluminescent groupings, adjacent pairs of the electroluminescent groupings being connected via two benzene rings linked by only a single covalent bond, at least one of the benzene rings bearing, at a position ortho to the covalent bond, a substituent of sufficient size that the two benzene rings are essentially not conjugated with each other. Preferred electroluminescent groupings comprise a chain of three or more para-phenylene groups connected to one another by amide, carboxy, ester, urea, urethane or vinyl groups. The polymers have a fixed conjugation length with predictable electroluminescent properties.
