Abstract:
It is an object of the present invention to provide a novel material that can be used for an electron injecting material. In addition, it is an object of the present invention to provide a light-emitting element that is able to broaden choices for an electrode material.An aspect of the present invention is an electron injecting material represented by a general formula (2). In the general formula (2), R6 is selected from the group consisting of an alkyl group having 1 to 4 carbon atoms, an alkenyl group having 1 to 4 carbon atoms, and an aryl group having 6 to 10 carbon atoms, where the alkenyl group and the aryl group may have a substituent.
