Abstract
A charge transporting material which allows for a low driving voltage and is superior in luminous efficiency and durability is provided. The charge transporting material comprising a compound represented by any one of the general formula (1-1) to (1-3) wherein R111 to R114, R121 to R125 and R131 to R135, L111 to L113, and L121 to L123 are as defined in the specification. Ar111 to Ar113 represent a substituent represented by any one of the general formulae (3-1) to (3-3); * represents a binding position to L121 to L123; and R311, R312, R321 to R325 and R331 to R335 are as defined in the specification:
Claims16
A charge transporting material comprising a compound represented by any one of the following General formula (1-1) to General formula (1-3):
- wherein, in the General formulae (1-1) to (1-3), R121 and R114, R131 and R125, and R135 and R111, are each independently a hydrogen atom, a deuterium atom, or are bound together to form a single bond;
- R112, R113, R122 to R124, and R132 to R134 each independently represent a hydrogen atom, a deuterium atom, or a substituent, and may be bound together to form a ring;
- L111 to L113 each independently represent a single bond or CR511R512 in which R511 and R512 each independently represent a hydrogen atom, a deuterium atom, or an alkyl group;
- L121 to L123 each independently represent a divalent linking group which is optionally partially or fully deuterated and contains at least two phenylene groups;
- and Ar111 to Ar113 each independently represent a substituent represented by any one of the following General Formulae (3-1) to (3-3):
- wherein, in the General Formulae (3-1) to (3-3), * represents a binding position to L121 to L123 in the General Formulae (1-1) to (1-3);
- R311, R312, R321 to R325 and R331 to R335 each independently represent a hydrogen atom, a deuterium atom, or a substituent;
- provided that
- the compound represented by any one of General formula (1-1) to General formula (1-3) is fully deuterated.
A charge transporting material compound selected from the group consisting of:
- wherein the compound is optionally partially or fully deuterated.
