PHOTOACTIVE LANTHANIDE COMPLEXES WITH PHOSPHINE OXIDES, PHOSPHINE OXIDE-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.
