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.
An electroluminescent polymer comprising a main chain and a plurality of side chains, each of said 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 polymer having side chains containing at least two different electroluminescent groups.
An electroluminescent polymer comprising a main chain and a plurality of side chains, the main chain comprising a polyether, polyurethane, polyimide, polyamide, polyurea, polyester, polyether ether ketone, poly(N-acylimine) or polysiloxane chain, each of said 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.
An electroluminescent polymer comprising a main chain and a plurality of side chains, each of said 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, each of the electroluminescent groups comprising a plurality of aromatic rings.
An electroluminescent polymer comprising a main chain and a plurality of side chains, each of said 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, each of the spacer groups comprising a methylene group, a polymethylene group or an ether, urea, urethane or imide linkage.
An electroluminescent polymer comprising a main chain and a plurality of side chains, the main chain comprising a polymethylene, poly(alkylmethylene), polyether, poly(alk)acrylate, polyurethane, polyimide, polyamide, polyurea, polyester, polyether ether ketone, poly(N-acylimine) or polysiloxane chain, each of said 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, each of the electroluminescent groups comprising a plurality of aromatic rings, and the polymer having side chains containing at least two different electroluminescent groups, and each of the spacer groups comprising a methylene group, a polymethylene group, or an ester, ether, urea, urethane, imide or amide linkage.
