Abstract
A quinone derivative is represented by general formula (1). In general formula (1), at least one of R1-R3 and at least one of R4-R6 each represent, independently of one another, an alkyl group having 4 to 10 carbon atoms or an alkyl group having 2 to 5 carbon atoms that has an aryl group having 6 to 14 carbon atoms. All other of R1-R3 and all other of R4-R6 each represent, independently of one another, an alkyl group having 1 to 6 carbon atoms, an aryl group having 6 to 14 carbon atoms, or a cycloalkyl group having 3 to 10 carbon atoms.
Claims8
A quinone derivative represented by general formula (1) shown below:
- where, in general formula (1),
- at least one of R1, R2, and R3 represents an alkyl group having 4 to 10 carbon atoms or an alkyl group having 2 to 5 carbon atoms that has an aryl group having 6 to 14 carbon atoms,
- all other of R1, R2, and R3 represents an alkyl group having 1 to 6 carbon atoms, an aryl group having 6 to 14 carbon atoms, or a cycloalkyl group having 3 to 10 carbon atoms,
- at least two of R1, R2, and R3 are optionally bonded together to form a ring.
- at least one of R4, R5, and R6 represents an alkyl group having 4 to 10 carbon atoms or an alkyl group having 2 to 5 carbon atoms that has an aryl group having 6 to 14 carbon atoms,
- all other of R4, R5, and R6 represents an alkyl group having 1 to 6 carbon atoms, an aryl group having 6 to 14 carbon atoms, or a cycloalkyl group having 3 to 10 carbon atoms, and
- at least two of R4, R5, and R6 are optionally bonded together to form a ring.
