Abstract:
An anthracene derivative represented by the following formula (1): wherein in the formula (1), L1 is selected from a single bond and a linking group, and the linking group is selected from a divalent arylene group, a divalent heterocyclic group, and a group formed by linking of 2 to 4 of divalent arylene groups and/or divalent heterocyclic groups. Ar1 is selected from the following formulas (2) and (3). In the formulas (2) and (3), X is selected from an oxygen atom and a sulfur atom. In the formula (2), any one of R11 to R14 is used for bonding to L1. In the formula (3), any one of R21 to R24 is used for bonding to L1. Ar2 is selected from a substituted or unsubstituted aryl group including 6 to 50 ring carbon atoms and a substituted or unsubstituted heterocyclic group including 5 to 50 ring atoms.
