Spirocycle-incorporated triphenylamine derivatives as an advanced organic electroluminescent material
For multi-color organic electroluminescent (EL) devices, new triphenylamine compounds attached to a spirocyclic framework were prepared from 2,7-bis(diphenylamino)-9-fluorenone. These amines showed exceedingly high Tg's or thermal stability as well as good electrochemical properties and sufficient EL characteristics, allowing practical application.
