Abstract: The present invention is directed to a semiconducting material comprising: i) a compound according to formula (I) wherein R1, R2 and R3 are independently selected from C1-C30-alkyl, C3-C30 cycloalkyl, C2-C30-heteroalkyl, C6-C30-aryl, C2-C30-heteroaryl, C1-C30-alkoxy, C3-C30-cycloalkyloxy, C6-C30 aryloxy, and from structural unit having general formula E-A-, wherein—A is a C6-C30 phenylene spacer unit, and—E is an electron transporting unit that is selected from C10-C60 aryl and C6-C60 heteroaryl comprising up to 6 heteroatoms independently selected from O, S, P, Si and B and that comprises a conjugated system of at least 10 delocalized electrons, and—at least one group selected from R1, R2 and R3 has the general formula E-A-; and ii) at least one complex of a monovalent metal having formula (II) wherein—M+ is a positive metal ion bearing a single elementary charge, and each of A1, A2, A3 and A4 is independently selected from H, substituted or unsubstituted C6-C20 aryl and substituted or unsubstituted C2-C20 heteroaryl, wherein a heteroaryl ring of at least 5 ring-forming atoms of the substituted or unsubstituted C2-C20 heteroaryl comprises at least one hetero atom selected from O, S and N.
