Abstract (en)

[origin: DE102005040285A1] White light-emitting organic LED contains at least one blue light-emitting fluoranthene derivative (I) as component A and at least one blue light-emitting arylamine derivative as component A, where the HOMO- and LUMO-energies of component A are different from those of component B, and provided that the LUMO-energies of component A are higher than the HOMO-energies of component B. White light-emitting organic LED contains at least one blue light-emitting fluoranthene derivative of formula (I) as component A and at least one blue light-emitting arylamine derivative as componente B, where the HOMO- and LUMO-energies of component A are different from those of component B, and provided that the LUMO-energies of component A are higher than the HOMO-energies of componente B. R 1>-R 5>H, alkyl, mono or fused aryl, heteroaryl, CH=CH 2, (E)- or (Z)-CH=CH-C 6H 5, acryloyl, methacryloyl, methylstyryl, O-CH=CH 2or glycidyl; X : alkyl, mono or fused aryl, a group of formula (a) or an oligophenyl; n : 1-10 where X is not an oligophenyl, and n = 1-20 when X = oligophenyl; and provided that at least 2 of R 1>-R 3>are not H. Independent claims are also included for the following: (1) composition comprising components A and B as above; (2) light-emitting layer comprising a composition as in (1); and (3) a device selected from stationary screens such as computer screens, TVs, screens in printers, kitchen/cooking appliances, advertising boards, illuminations, information boards, mobile screens such as screens in mobile phones, laptops, vehicles and destination displays on buses and railways, all containing white light-emitting organic LED as above.
