Abstract
A compound represented by the following general formula is useful as an electron barrier material. R1 to R21 each are H, a deuterium atom, or a substituent except a cyano group; X represents O or S.
Claims14
An electron barrier material containing a compound represented by the following general formula (1):
- wherein R1 to R21 each independently represent a hydrogen atom, a deuterium atom, or a substituent not including a cyano group;
- one combination of R2 and R13, R13 and R14, and R14 and R15 can bond to each other to form a benzofuro skeleton or a benzothieno skeleton;
- R1 to R11, and R16 to R21 do not bond to the other R1 to R11, R16 to R21 or R12 to R15 to form a cyclic structure;
- and
- X represents an oxygen atom or a sulfur atom.
