| 摘要 |
The present invention relates to a main group metal complex of groups 13 to 16 comprising at least one ligand of the structure (I), where R1 und R2 can be, independently of each other, oxygen, sulfur, selenium, NH or NR4, where R4 is selected from the group consisting of alkyl or aryl and can be connected to R3; and R3 is selected from the group consisting of 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, wherein in suitable radicals one or more non-adjacent CH2-groups can be substituted independently of one another by -O-, -S-, -NH-, -NR°-, -SiR°R°°-, -CO-, -COO-, -OCO-, -OCO-O-, -SO2-, -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. |
