It is an object of the present invention to provide a light-emitting
substance which is resistant to repetition of an oxidation reaction. It
is another object of the invention to provide a light-emitting element
which is resistant to repetition of a reduction reaction. An aspect of
the present invention is an anthracene derivative represented by a
general formula (1). In the general formula (1), R1 represents hydrogen
or an alkyl group having 1 to 4 carbon atoms; R2 represents any one of
hydrogen, an alkyl group having 1 to 4 carbon atoms, and an aryl group
having 6 to 12 carbon atoms, which may have a substituent or no
substituent; Ph1 represents a phenyl group, which may have a substituent
or no substituent; and X1 represents an arylene group having 6 to 15
carbon atoms. ##STR00001##
