Photoactive lanthanide complexes with phosphine oxides, phosphine oxides-sulfides, pyridine N-oxides, and phosphine oxide-pyridine N-oxides, and devices made with such complexes

摘要

The present invention is generally directed to luminescent lanthanide compounds with phosphine oxide, phosphine oxide-sulfide, pyridine N-oxide, and phosphine oxide-pyridine N-oxide ligands. It also relates to electronic devices in which the active layer includes a lanthanide complex.
