Abstract:
1. A metal complex for doping an organic semiconducting matrix material having a structure selected from: wherein a is —CR wherein the bonds b-d and c-e or b-d and a-c may, at the same time or independently of one another, be unsaturated, wherein the bonds b-d, a-c, and c-e may, at the same time or independently of one another, comprise part of a saturated or unsaturated ring system which may also comprise at least one heteroelement selected from the group consisting of: O, S, Se, N, P, Si, Ge, and Sn, wherein the bonds b-d, a-c, and c-e may, at the same time or independently of one another comprise part of an aromatic or condensed aromatic ring system which may also comprise at least one heteroelement selected from the group consisting of: O, S, Se, and N, wherein the atom E is an element from the main group, wherein the structural element a-E-b may comprise a component of a saturated or unsaturated ring system which may also comprise at least one heteroelement selected from the group consisting of: O, S, Se, N, P, Si, Ge, and Sn, or the structural element a-E-b may comprise a component of an aromatic ring system which may also comprise at least one heteroelement selected from the group consisting of: O, S, Se, and N, wherein the metal M is a transition metal; wherein a is —CR wherein R is selected independently from C wherein the bonds a-c, b-d, c-e, and d-f, but not simultaneously a-c and c-e and not simultaneously b-d and d-f, may be unsaturated, wherein the bonds a-c, b-d, c-e, and d-f may comprise part of a saturated or unsaturated ring system which may also comprise at least one heteroelement selected from the group consisting of: O, S, Se, N, P, Si, Ge, and Sn, wherein the bonds a-c, b-d, c-e, and d-f may comprise part of an aromatic or condensed aromatic ring system which may also comprise at least one heteroelement selected from the group consisting of: O, S, Se, and N, wherein the atom E is an element from the main group, wherein the structural element a-E-b may comprise a component of a saturated or unsaturated ring system which may also comprise at least one heteroelement selected from the group consisting of: O, S, Se, N, P, Si, Ge, and Sn, wherein the structural element a-E-b canmay comprise a component of an aromatic ring system which may also comprise at least one heteroclement selected from the group consisting of: O, S, Se, and N, wherein the metal M is a transition metal; wherein a is —CR wherein the bonds a-c, c-e, e-f, and b-d, but not simultaneously a-c, c-e, and e-f, and not simultaneously a-c and c-e, and not simultaneously c-e and e f, may be unsaturated, wherein the bonds a-c, c-e, e-f, and b-d may comprise part of a saturated or unsaturated ring system which may also comprise at least one heteroelement selected from the group consisting of: O, S, Se, N, P, Si, Ge, and Sn, wherein the bonds a-c, c-e, e-f, and b-d may comprise part of an aromatic or condensed aromatic ring system which may also comprise at least one heteroelement selected from the group consisting of: O, S, Se, and N, wherein the atom E is an element from the main group, wherein the structural element a-E-b may comprise a component of a saturated or unsaturated ring system which may also comprise at least one heteroelement selected from the group consisting of: O, S, Se, N, P, Si, Ge, and Sn, wherein the structural element a-E-b may comprise a component of an aromatic ring system which may also comprise at least one heteroelement selected from the group consisting of: O, S, Se, and N, wherein the metal M is a transition metal; or wherein a is —CR wherein the bonds a-c, c-e, b-d, d-f, and f-g, but not simultaneously a-c and c-e, and not simultaneously b-d, d-f, and f-g, and not simultaneously b-d and d-f, and not simultaneously d-f and f-g, may be unsaturated, wherein the bonds a-c, c-e, b-d, d-f, and f-g may comprise part of a saturated or unsaturated ring system, which may comprise at least one heteroelement selected from the group consisting of: O, S, Se, N, P, Si, Ge, and Sn, wherein the bonds a-c, c-e, b-d, and f-g may comprise part of an aromatic or condensed aromatic ring system which may comprise at least one heteroelement selected from the group consisting of: O, S, Se, and N, wherein the atom E is an element from the main group, wherein the structural element a-E-b may comprise a component of a saturated or unsaturated ring system which may comprise at least one heteroelement selected from the group consisting of: O, S, Se, N, P, Si, Ge, and Sn, wherein the structural element a-E-b may comprise a component of an aromatic ring system which may comprise at least one heteroelement selected from the group consisting of: O, S, Se, and N, wherein the metal M is a transition metal.
