CONDENSED POLYCYCLIC COMPOUND CAPABLE OF PROVIDING HIGH ORGANIC LIGHT EMITTING DIODE WITH EXCELLENT COLOR PURITY, LUMINOUS EFFICIENCY AND DURABILITY, AND AN ORGANIC LIGHT-EMITTING DIODE USING THE COMPOUND

摘要

PURPOSE: A condensed polycyclic compound is provided to provide a light-emitting diode which has high quantum yield, good chromaticity, high durability and high efficiency, and emits blue light.;CONSTITUTION: A condensed polycyclic compound comprises at least one compound represented by at least one of chemical formula 1, 2, 8 and 9. In chemical formula 1, 2, 8 and 9, Q is an electron-withdrawing substituent selected from compounds indicated in chemical formula 3-7. In chemical formula 3 and 4, R1-R4 are substituents selected from hydrogen, C1-4 alkyl group and cyano group, and can be the same of different to each other. In chemical formula 7, R5 is one of hydrogen and a methyl group.;COPYRIGHT KIPO 2013
