The “heterocyclic group” described herein is a ring group including at least one hetero atom in the ring atom. Specific examples of the hetero atom include a nitrogen atom, an oxygen atom, a sulfur atom, a silicon atom, a phosphorus atom and a boron atom.
The “heterocyclic group” described herein may be a monocyclic group, or a fused ring group.
The “heterocyclic group” described herein may be an aromatic heterocyclic group, or an aliphatic heterocyclic group.
Specific examples (specific example group G2) of the “substituted or unsubstituted heterocyclic group” include an unsubstituted heterocyclic group and a substituted heterocyclic group described below. (Here, the unsubstituted heterocyclic group refers to a case where the “substituted or unsubstituted heterocyclic group” is the “unsubstituted heterocyclic group,” and the substituted heterocyclic group refers to a case where the “substituted or unsubstituted heterocyclic group” is the “substituted heterocyclic group”. Hereinafter, the case of merely “heterocyclic group” includes both the “unsubstituted heterocyclic group” and the “substituted heterocyclic group”.
