Patent ID: 7632577

Claim:
An organic light-emitting device comprising a pair of electrodes consisting of an anode and a cathode and organic compound-containing layers sandwiched between the pair of electrodes, wherein (a) at least one layer of the organic compound-containing layers contains at least one compound selected from the group consisting of compounds represented by the following general formula: wherein Y 1 and Y 3 can be bonded to Y 2 and Y 4 respectively to form a ring; Y 1 to Y 4 are the same or different and are each independently a group selected from the group consisting of alkyl, aralkyl, aryl, heterocyclic, amino, silyl, alkylene, aralkylene, alkenylene, imino, —SiH 2 —, silylene, carbonyl, ether and thioether, each having no substituent or a substituent which can include a linking group consisting of arylene or divalent heterocyclic, each having no substituent or a substitutent; and at least one compound selected from the group consisting of compounds represented by the following general formula [6]: wherein R 19 and R 20 are the same or different and are hydrogen or a group selected from the group consisting of a alkyl, aralkyl and aryl, each having no substituent or a substituent; any pair of R 19 combined to their respective fluorene structures are the same or different to each other; any pair of R 20 combined to their respective fluorene structures are the same or different to each other; R 21 to R 24 are hydrogen, halogen, cyano, a substituted silyl or a group selected from the group consisting of alkyl, aralkyl and alkoxy, each having no substituent or a substituent; and p is an integer from 2 to 10; and (b) at least one layer of the organic compound-containing layers is a light-emitting layer.
