Patent

CA 2360644

This invention relates to: (a) fluorene copolymers comprising at least 10 percent (by residual monomeric units) of 9-substituted and/or 9,9- disubstituted fluorene moieties and at least two other monomeric units containing delocalized p-electrons, (b) polymer blends comprising at least 10 weight percent of a copolymer specified in (a), and (c) electronic devices (such as polymer light emitting diodes) containing one or more films derived from these copolymers.

L'invention concerne: (a) des copolymères de fluorène comprenant au moins 10 pour cent (par motif monomère résiduel) de parties fluorène substituées en position 9 et bisubstituées en position 9, 9, et au moins deux autres motifs monomères contenant des électrons p délocalisés; (b) des mélanges polymères comprenant au moins 10 pour cent en poids d'un copolymère spécifié dans (a); et (c) des dispositifs électroniques (tels que des diodes électroluminescentes polymères) contenant un ou plusieurs films dérivés de ces copolymères.
