A novel pyrrolotriazole derivative is disclosed, represented by any one of formulae (I), (II), or (III):
wherein:
R¹, R², R³ and R⁴ each independently represents a hydrogen atom or a nonmetallic atomic group;
R⁵ and R⁶ each independently represents a hydrogen atom, alkyl group, an aryl group, or a heterocyclic group;
R⁷ represents an electrophilic group having a Hammett's substituent constant σp of 0.15 or more;
R⁸ and R⁹ each independently represents a hydrogen atom or a nonmetallic atomic group;
the sum of Hammett's substituent constant σp of R⁷ and R⁸ is 0.65 or more;
R¹ and R², and/or R² and R⁵, and/or R⁵ and R⁶, and/or R⁶ and R³, and/or R³ and R⁴ may be connected to each other to form a cyclic structure;
R⁷ and R⁸ may be connected to each other to form a cyclic structure; and
Z represents a hydrogen atom, a halogen atom, an arylthio group, a heterocyclic thio group, an arylsulfinyl group, or a nitroso group.
