(FR) MATÉRIAUX ÉLECTROLUMINESCENTS ET DISPOSITIF OPTIQUE
Abstract
(EN)
An electroluminescent material comprises the following structural unit (1): where X is selected from a group consisting of NR, O, S, SO, SO2, CR2, PR, POR, BR, SiR2; where R is a substituent group and Ar1 and Ar2 comprise aromatic rings; and, wherein Ar1 or Ar2 is fused to a further aryl system Ar3. An optical device comprises a first electrode for injection of positive charge carriers, a second electrode for injection of negative charge carriers and a layer located between the first and second electrode comprising the electroluminescent material.
(FR)
Le matériau électroluminescent selon l’invention comprend l’unité structurale suivante : où X est sélectionné parmi un groupe constitué de NR, O, S, SO, SO2, CR2, PR, POR, BR, SiR2; où R est un groupe substituant et Ar1 et Ar2 comprennent des cycles aromatiques; et Ar1 ou Ar2 étant fusionné à un autre système aryle Ar3. Le dispositif optique selon l’invention comprend une première électrode pour l’injection de porteurs de charges positives, une seconde électrode pour l’injection de porteurs de charges négatives et une couche située entre les première et seconde électrodes comprenant le matériau électroluminescent.
