Claim 3:
4. The heteroleptic complex according to claim 1, wherein:
M is Ir,
A1 is C,
A2 is N or C,
n, m are each independently 1 or 2, where the sum of n and m is 3,
R1 is a linear or branched alkyl radical having 1 to 20 carbon atoms, substituted or unsubstituted aryl radical having 6 to 30 carbon atoms, substituted or unsubstituted heteroaryl radical having 5 to 18 carbon atoms and/or heteroatoms,
R2, R3 are each independently hydrogen, linear or branched alkyl radical having 1 to 20 carbon atoms, substituted or unsubstituted aryl radical having 6 to 30 carbon atoms, substituted or unsubstituted heteroaryl radical having 5 to 18 carbon atoms and/or heteroatoms,
R4, R5, R6 are each independently hydrogen, linear or branched alkyl radical having 1 to 20 carbon atoms, substituted or unsubstituted aryl radical having 6 to 30 carbon atoms,
R7, R8 together form an unsaturated C2 bridge, to which a substituted or unsubstituted, five- to eight-membered ring comprising carbon atoms and/or heteroatoms, may be fused,
R9 is a free electron pair if A2 is N or, if A2 is C, hydrogen, linear or branched alkyl radical having 1 to 20 carbon atoms, substituted or unsubstituted aryl radical having 6 to 30 carbon atoms, substituted or unsubstituted heteroaryl radical having 5 to 18 carbon atoms and/or heteroatoms,
R10 is a linear or branched alkyl radical having 1 to 20 carbon atoms, substituted or unsubstituted aryl radical having 6 to 30 carbon atoms, and
R11, R12, R13, R14 are each independently hydrogen or linear or branched alkyl radical having 1 to 20 carbon atoms,
R1 and R14 optionally together form a saturated or unsaturated, linear or branched bridge optionally comprising heteroatoms, aromatic units, heteroaromatic units and/or functional groups and having a total of 1 to 30 carbon atoms and/or heteroatoms, to which a substituted or unsubstituted, five- to eight-membered ring comprising carbon atoms and/or heteroatoms is optionally fused.
