Main group metal complexes as p-dopants for organic electronic matrix materials

Abstract

A metal complex of a metal from groups 13 to 16 uses a ligand of the structure (I), where Rand Rcan independently be oxygen, sulfur, selenium, NH or NR, where Ran alkyl or aryl and can be connected to R. Ris an alkyl, long-chain alkyl, alkoxy, long-chain alkoxy, cycloalkyl, halogenalkyl, aryl, arylene, halogenaryl, heteroaryl, heteroarylene, heterocycloalkylene, heterocycloalkyl, halogenheteroaryl, alkenyl, halogenalkenyl, alkynyl, halogenalkynyl, ketoaryl, halogenketoaryl, ketoheteroaryl, ketoalkyl, halogenketoalkyl, ketoalkenyl, halogenketoalkenyl, where in suitable radicals, one or more non-adjacent CH— groups can be substituted independently of one another by —O—, —S—, —NH—, —NR—, —SiRR—, —CO—, —COO—, —OCO—, —OCO—O—, —SO—, —S—CO—, —CO—S—, —CY1=CY2 or —C═C—, specifically in such a way that O and/or S atoms are not connected directly to one another, are likewise optionally substituted with aryl- or heteroaryl preferably containing 1 to 30 C atoms, as a dopant for matrix materials in organic electronic components.
