FLUORENE COMPOUND AND ORGANIC ELECTROLUMINESCENT ELEMENT

摘要

PROBLEM TO BE SOLVED: To obtain a new fluorene compound useful as an organic electroluminescent element. SOLUTION: The organic EL element having a high efficiency and a high-luminance optical output is obtained by using a fluorene compound represented by general formula (1) (R1-R14are each hydrogen, an alkyl group, an aryl group or the like; Y1and Y2are each hydrogen an aromatic condensed ring which may contain a substituent group; l-t are each an integer of 0-10).
