Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A white-emitting monomolecular compound represented by Formula 23: wherein R 2 , R 3 , and R4 are each independently selected from the group consisting of a hydrogen atom, a hydroxy group, a linear, branched or cyclic C1-C20 alkyl group, a C1-C20 alkoxy group, a substituted or unsubstituted C1-C20 carbonyl group, an aryloxy group substituted with an aroma…
