Abstract
The present disclosure provides a compound of Formula I wherein M is a metal selected from the group consisting of Cu, Ag, and Au; T is a five-membered or six-membered heterocyclic ring, which is optionally substituted, wherein T includes a carbene carbon coordinated to M, or T is aromatic and includes a sp2 nitrogen coordinated to M; L is a group comprising a coordinating member selected from the group consisting of C, N, O, S, and P, wherein the coordinating member coordinates L to M; and Q1 and Q2 are each independently a linker, wherein the linker connects T to the coordinating member of L to form a macrocyclic ligand coordinated to M.
Claims19
A compound of Formula I
- wherein
- M is a metal selected from the group consisting of Cu, Ag, and Au;
- T is a five-membered or six-membered heterocyclic ring, which is optionally substituted, wherein T includes a carbene carbon coordinated to M, or T is aromatic and includes a sp2 nitrogen coordinated to M;
- L is a group comprising an anionic coordinating member selected from the group consisting of C, N, O, S, and P, wherein the anionic coordinating member coordinates L to M;
- and
- Q1 and Q2 are each independently a linker, wherein the linker connects T to the anionic coordinating member of L to form a macrocyclic ligand coordinated to M;
- wherein the compound is neutral.
An organic electroluminescent device (OLED) comprising:
- an anode, a cathode, and an organic layer disposed between the anode and the cathode comprising a compound of Formula I,
- wherein
- M is a metal selected from the group consisting of Cu, Ag, and Au;
- T is a five-membered or six-membered heterocyclic ring, which is optionally substituted, wherein T includes a carbene carbon coordinated to M, or T is aromatic and includes a sp2 nitrogen coordinated to M;
- L is a group comprising an anionic coordinating member selected from the group consisting of C, N, O, S, and P, wherein the anionic coordinating member coordinates L to M;
- and
- Q1 and Q2 are each independently a linker, wherein the linker connects T to the anionic coordinating member of L to form a macrocyclic ligand coordinated to M;
- wherein the compound is neutral.
A consumer product comprising an organic light-emitting device (OLED), the OLED comprising an anode, a cathode, and an organic layer disposed between the anode and the cathode comprising a compound of Formula I,
- wherein
- M is a metal selected from the group consisting of Cu, Ag, and Au;
- T is a five-membered or six-membered heterocyclic ring, which is optionally substituted, wherein T includes a carbene carbon coordinated to M, or T is aromatic and includes a sp2 nitrogen coordinated to M;
- L is a group comprising an anionic coordinating member selected from the group consisting of C, N, O, S, and P, wherein the anionic coordinating member coordinates L to M;
- and
- Q1 and Q2 are each independently a linker, wherein the linker connects T to the anionic coordinating member of L to form a macrocyclic ligand coordinated to M;
- wherein the compound is neutral.
