Patent

CA 2657126

The present invention relates to polymers comprising repeating unit(s) of the formula (I), and their use in electronic devices. The polymers according to the invention have excellent solubility in organic solvents and excellent film-forming properties. In addition, high charge carrier mobilities and high temperature stability of the emission color are observed, if the polymers according to the invention are used in polymer light emitting diodes (PLEDs).

La présente invention concerne des polymères comprenant une ou des unités récurrentes de la formule (I), et leur utilisation dans des dispositifs électroniques. Les polymères selon l'invention présentent une excellente solubilité dans les solvants organiques et d'excellentes propriétés filmogènes. En outre, on observe une mobilité élevée des supports de charge et une stabilité élevée à la température de la couleur d'émission, si les polymères suivant l'invention sont utilisés dans des diodes émettrices de lumières, polymères (PLED).
