Abstract
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.
