HOLE INJECTION MATERIAL

摘要

The present invention relates to an electronic device, which comprises a compound of the formula (I), wherein R1 and R2 independently of one another are C1-C12alkyl, C1-C12alkyl, which is interrupted by one, or more oxygen atoms, C3-C8cycloalkyl which is unsubstituted or substituted by C1-C4alkyl, unsubstituted C6-C12aryl, or C3-C7heteroaryl, or benzyl, or C6-C12aryl, or C3-C7heteroaryl, or benzyl which is substituted by F, Cl, Br, C1-C6alkyl, C1-C6alkoxy or di(C1-C6alkylamino). The compound of the formula (I) is a n-type organic material, which is an intrinsically good semiconducting material, resulting in a high device stability and reliability.
