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

  • R111 to R118 which do not form the unsaturated ring represented by the formula (20), do not form a substituted or unsubstituted, saturated or unsaturated ring other than the unsaturated ring represented by the formula (20), and are not a single bond bonding with L101 or L102, and R121 to R124 which are not a single bond bonding with L101 or L102 are independently
    a hydrogen atom, a halogen atom, a cyano group, a nitro group,
    a substituted or unsubstituted alkyl group including 1 to 50 carbon atoms,
    a substituted or unsubstituted alkenyl group including 2 to 50 carbon atoms,
    a substituted or unsubstituted alkynyl group including 2 to 50 carbon atoms,
    a substituted or unsubstituted cycloalkyl group including 3 to 50 ring carbon atoms,
    —Si(R901)(R902)(R903),
    —O—(R904),
    —S—(R905),
    —N(R906)(R907),
    a substituted or unsubstituted aryl group including 6 to 50 ring carbon atoms, or
    a substituted or unsubstituted monovalent heterocyclic group including 5 to 50 ring atoms; and

    • R901 to R907 are as defined in the formula (11).

    In one embodiment, it is preferable that R112 or R113 in the monovalent group represented by the formula (12) be a single bond bonding with L101 or L102 in the formula (11).
