SAM LAYERS WITH AN HTL FUNCTION

摘要

The present invention relates to ?,?,?',?'-tetraarylbenzidine derivatives of the general formula (I) in which R can in each case be identical or different and in each case represents a hydrogen atom, a halogen atom, or an optionally substituted, straight-chain or branched C1-C30-alkyl group, Ar can in each case be identical or different and represents an optionally mono- or polysubstituted aryl radical, wherein at least one of the aryl radicals is substituted by at least one radical -R1-NR2R3, in which R1 represents a straight-chain or branched C2-C20-alkylene radical and R2 and R3 can be identical or different and in each case represent a hydrogen atom or a C1-C5-alkyl group. The invention also relates to a layered body, a process for the production of a layered body, the layered body obtainable by this process, electronic components comprising a layered body and the use of an ?,?,?',?'-tetraarylbenzidine derivative.
