US 8,569,510 B2 · White-emitting compounds using excited-state intramolecular proton transfer, organic electroluminescent element and laser material using the same

Abstract

Provided are a white-emitting monomolecular compound using excited-state intramolecular proton transfer (ESIPT) characteristics, and an organic electroluminescence device and a laser device comprising same. The white-emitting monomolecular compound according to the present invention is prepared by covalently bonding at least two types of molecules which produce different colors and have excited-state intramolecular proton transfer (ESIPT) characteristics. The white-emitting monomolecular compound according to the present invention achieves white luminescence irrespective of the concentration thereof and of the state of the materials thereof, and therefore can be used in a variety of fields including an organic electroluminescence device and a laser device.
