In the present disclosure, the number of carbon atoms of deuterated alkyl having carbon atoms 1 to 10 is, for example, 1, 2, 3, 4, 5, 6, 7, 8 or 10. Specific examples of deuterated alkyl include, but are not limited to, trideuteromethyl.
In the present disclosure, the number of carbon atoms of haloalkyl having 1 to 10 carbon atoms is, for example, 1, 2, 3, 4, 5, 6, 7, 8 or 10. Specific examples of haloalkyl include, but are not limited to, trifluoromethyl.
In the present disclosure, a ring system formed by n atoms is an n-membered ring. For example, phenyl is a 6-membered ring. A 3 to 15-membered ring refers to a cyclic group having 3 to 15 ring atoms. A 3 to 15-membered ring may be, for example, cyclopentane, cyclohexane, a fluorene ring, a benzene ring, etc.
