| titleOfInvention | Host material for organic electroluminescence devices |
| abstract | A novel class of host materials for organic electroluminescent applications. The materials comprise a general Formula I: n n n n n n n n n n n n wherein R 2 may be a substituent selected from the group consisting of hydrogen, alkyl, substituted or unsubstituted aryl, heteroaryl, and alicyclic alkyl; wherein at least one of the R 1 substituents is different from R 2 and chosen from Group A where Group A consists of substituted or unsubstituted aryl, heteroaryl, phenyl, tolyl, naphthyl, anthryl, penylanthryl, dipheylanthryl, biphenylyl, phenylvinyl, and diphenylvinyl; and wherein if only one of the R 1 substituents is a substitutent chosen from Group A, then the other R 1 substituent is selected from the group consisting of hydrogen, an alkyl group with, for example, from 1 to about 25 carbon atoms, an alicyclic alkyl group with, for example, from about 3 to about 15 carbon atoms, an alkoxy group with from 1 to about 25 carbon atoms, a dialkylamino group with from about 2 to about 25 carbon atoms, methyl, butyl, cyclohexyl, methoxy, ethoxy, butyloxy, dimethylamino, diethylamino, a cyano group and halogens. This novel class of host materials are carbazole derivatives with an unique structure, which are particularly useful for the design of blue emitting organic EL devices. |
