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

   
   

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.

La présente invention est généralement dirigée vers les composés luminescents de lanthanide avec de l'oxyde de phosphine, l'oxyde-sulfure de phosphine, l'N-oxyde de pyridine, et les ligands d'N-oxyde d'oxyde-pyridine de phosphine. Elle se relie également aux dispositifs électroniques en lesquels la couche active inclut un complexe de lanthanide.
