摘要：
Anthracene derivatives each having a structure including an anthracene skeleton, a phenanthrene skeleton selected from among various phenanthrene skeletons different in bonding site which is bonded to the 9-position of the anthracene skeleton and a group selected from among various aryl groups and so on which is bonded to the 10-position of the anthracene skeleton. Organic EL devices made by using the derivatives exhibit high light emission efficiency and a long life.
