Or N—C≡N (wherein R and R ′ each independently represents a hydrogen atom or an arbitrary substituent), but at least one of X and Y represents a group other than an oxygen atom. Z and Z ′ each independently represents an oxygen atom, a sulfur atom, or —NR ″ — (where R ″ represents a hydrogen atom or an arbitrary substituent). )
