According to embodiments described in the specification, a chemical process includes the steps of reacting a chemical reaction fluid including a solvent, 1,2-biaryl gem-dibromocyclopropane or 1,2-biphenyl-gem-dibromocyclopropane, and a metal salt including a silver tetrafluoroborate salt at low temperatures to make 1-phenyl-2-bromo indenes in a vessel that is capable of being closed.

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.
