ORGANIC COMPOUND AND ELEMENT USING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain an organic compound having high chemical and thermal stabilities and functions of carrier-transporting property, and the like. SOLUTION: This organic compound has a skeleton in which three or more aromatic rings are bonded to each other at mutual arbitrary positions and is composed of only >=18 carbon atoms and F. Specifically, the organic compound has a structure represented by the formula C6nF4n+2 or the following formula (1) or (2) or is a compound composed of only C and F, in which a polyacene ring including naphthalene ring is directly bonded. The compound exhibits transporting properties of electron and positive hole and can be used as an electron transporting layer, or the like, of an EL element and can be used as a positive hole-blocking layer when positive hole-blocking function is exhibited and can improve the element life when the compound is used as a protective film.
