N-PHENYL TRISCARBAZOLE

The present invention relates to a novel triscarbazole compound having substituent on N-phenyl, which can be represented by Formula (I). wherein R1 is selected from the group consisting of hydrogen, halogen or alkyl or alkoxy group having 1 to 20 carbon atoms wherein at least one hydrogen atom is optionally replaced by halogen; RA, RB, RC, RD and RE are any of substituents other than hydrogen wherein at least two of R1 and RA may further form a fused ring; and i, j, k, l and m are same or different at each occurrence and represent an integer from 0 to 4, with the proviso that when R1 is hydrogen, i is not 0. By introduction of the substituent on N-phenyl, the device efficiency, stability and lifetime can be increased while maintaining the solubility. These compounds can be used in various organic devices such as organic light emitting diodes, photovoltaic cells or organic semiconductor devices.

HOST MATERIAL FOR LIGHT-EMITTING DIODES

The present invention relates to a host material comprising a compound having two carbazole moieties which is suitable for blue-emitting OLEDs. Surprisingly, it has been found that when appropriate substituents are present in the carbazole structure, the solubility of the compounds can be improved without any adverse effect on the OLED performance. The present invention further relates to the use of the host materials and to an organic light emitting device comprising the host material.
