EP1029909 ORGANIC ELECTROLUMINESCENCE DEVICE AND PHENYLENEDIAMINE DERIVATIVE

The invention is to provide an organic EL device having a long life time that can reduce the driving voltage of the organic EL device, and to provide a material having a small ionization potential and exhibiting a large hole mobility by using as a layer or a zone. The organic electroluminescence device comprises a pair of electrodes and an organic light emitting layer sandwiched in the electrodes, characterized in that a hole transporting zone provided between the electrodes comprises the phenylenediamine derivative represented by the specific structural formulae, and the phenylenediamine derivative has a hole mobility of 10<-4> cm<2>/V.s or more upon using as a layer or a zone, with the organic light emitting layer containing a charge injection auxiliary.

L'invention concerne un dispositif électroluminescent à faible tension de commande et longue durée de vie, comprenant un matériau à faible potentiel d'ionisation et mobilité de trous élevée en cas d'utilisation comme couche ou zone de transport de trous. Le dispositif considéré comporte une paire d'électrodes et une couche organique luminescente prise en sandwich entre les deux électrodes. Une zone de transport de trous comprise entre les électrodes contient un dérivé de phénylènediamine défini par une formule structurelle spécifique et présentant une mobilité de trous égale ou supérieure à 10^-1 cm²/V•s lorsque le matériau est utilisé comme couche ou zone de transport de trous. Par ailleurs, la couche luminescente renferme un matériau favorisant l'injection.
