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.
