摘要

An organic electroluminescence device, comprising: a cathode; an anode; and an emitting layer disposed between the cathode and the anode, wherein the emitting layer includes a compound represented by the following formula (1) and a compound represented by the following formula (11), provided that at least one of Ar101 and Ar102 is a monovalent group represented by the following formula (12).

說明書

In the formula (18a), L101a and L102a are independently a single bond, or a substituted or unsubstituted arylene group including 6 to 10 ring carbon atoms;

    • Ar102a is a substituted or unsubstituted aryl group including 6 to 10 ring carbon atoms; and
    • R131a and R132a are independently
      a hydrogen atom,
      a substituted or unsubstituted aryl group including 1 to 18 ring carbon atoms, or
      a substituted or unsubstituted alkyl group including 1 to 10 carbon atoms.

In one embodiment, R131a and R132a in the formulas (18) and (18a) are independently a substituted or unsubstituted phenyl group, or a substituted or unsubstituted methyl group.

In one embodiment, R131a and R132a in the formulas (18) and (18a) are independently an unsubstituted phenyl group, or an unsubstituted methyl group.

In one embodiment, R131a and R132a in the formulas (18) and (18a) are independently a substituted or unsubstituted alkyl group including 1 to 10 carbon atoms.

In one embodiment, R131a and R132a in the formulas (18) and (18a) are independently a substituted or unsubstituted methyl group.

In one embodiment, R131a and R132a in the formulas (18) and (18a) are independently an unsubstituted methyl group.
