1-36. (canceled)
A method for forming an optoelectronic component comprising:
- providing an optoelectrical component;
- and
- incorporating an oligomer into the optoelectrical component, wherein the oligomer comprising
- at least one positively charged metal complex
- and at least one negatively charged metal complex,
- wherein the metal complexes are of
- K1=[L1L2L3L4M1]n+ and formula (I)
- K2=[L5L6L7L8M2]n− formula (II)
- wherein M1 and M2 each is a metal center, chosen independently from each other from Ir(I), Rh(I), Pt(II), Pd(II) and Au(III) and
- L1-L4 and L5-L8 each represent a neutral or charged ligand, wherein two or more of L1-L4 and L5-L8 can also be connected to each other, and wherein
- n is 1 or 2.
