Abstract

A single-step method of making tetradentate platinum complexes is disclosed. The method advantageously allows the formation of a platinum complex in a single step, even with sterically hindered ligands, without the use of highly reactive intermediates. The compounds made by the disclosed method are useful in OLED applications.

First claim

The invention claimed is:

1. A method of preparing a metal complex comprising:
(a) combining at least one ligand L with a metal precursor to form a mixture;
wherein the ligand L is at least bidentate;
wherein the metal precursor is a Pt compound containing at least one bidentate ligand L′;
wherein no halogen is directly connected to the Pt;
(b) reacting the mixture to form a reaction product;
wherein the reaction product is a tetradentate complex having at least two atom…
