Claims17
A material for an organic light-emitting device, the material comprising
- a repeating unit represented by Formula 1:
- wherein, in Formula 1,
- R1 is selected from a single bond, a phenylene group, and a group represented by one of Formulae a1 to a9:
- wherein, in Formulae a1 to a9,
- R22 is a C1-C6 alkyl group,
- X21 and X22 are each independently selected from an oxygen atom and a sulfur atom;
- A is selected from an adamantylene group, a diadamantylene group, a triadamantylene group, and a tetraadamantylene group;
- and
- X1 is a charge transport unit represented by one of Formulae b1 to b13:
- wherein, in Formulae b1 to b13,
- R311, R312, R313, R321, R322, R331, R341, R351, R352, R361, R362, R363, R371, R372, R381, R391, R3101, R3111, R3112, R3113, R3121, R3122, R3123, R3124, R3125, R3131 and R3132 are each independently selected from a hydrogen atom, a C1-C6 alkyl group, and a group represented by one of Formulae c1 to c16:
- wherein, in Formulae c1 to c16,
- p is 0 or 1;
- and
- Z11, Z12, Z21, Z31, Z41, Z42, Z51, Z52, Z53, Z61, Z62, Z71, Z72, Z81, Z82, Z91, and Z92 are each independently selected from a C1-C6 alkyl group, a methoxy group, and a group represented by one of Formulae d1 to d7:
- wherein, in Formulae d1 to d7,
- alkyl indicates a C1-C6 alkyl group;
- Y11, Y12, Y21, Y31, Y41, Y42, Y51, Y52, Y61, Y62, and Y63 are each independently a group represented by one of Formulae e1 to e11:
- wherein, in Formulae e1 to e11,
- R411, R412, R421, R431, R441, R442, R451, R452, R461, and R462 are each independently selected from a hydrogen atom, a C1-C6 alkyl group, a phenyl group, and a tolyl group.
