WHITE-EMITTING COMPOUNDS USING EXCITED-STATE INTRAMOLECULAR PROTON TRANSFER, ORGANIC ELECTROLUMINESCENT ELEMENT AND LASER MATERIAL USING THE SAME

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.

Hydrogen Bond-Induced Rigid Oligoanthranilamide Ribbons That Are Planar and Straight

(Matrix presented) A new series of oligoanthranilamides has been synthesized starting from suitably modified p-phenylenediamine and p-phthalic acid derivatives. Due to strong intramolecular three-center hydrogen bonds, the new oligomers self-assemble into highly stable straight and planar molecular ribbons, which have been characterized by X-ray crystallography and 1H NMR, IR, and UV-vis spectroscopy.

Synthesis and optically acid-sensory and electrochemical properties of novel polyoxadiazole derivatives

A series of PPV-based polyoxadiazoles have been synthesized by Horner and Suzuki coupling polymerization to investigate their structure-property relationship. These copolymers exhibit good thermal stability (decomposition temperature around 352-413°C). Ex
