1. A cyclic amide transition metal complex represented by formula (1)
 wherein R1, R2, R3, R4, R5 and R6 are the same or different and each represent a hydrogen atom, a C1 to C16 hydrocarbon, a perfluoroalkyl group or a halogen
atom, R7 represents an optionally substituted C1 to C18 alkylene or a perfluoroalkylene group, A represents a group having 1 to 3 quatemary
ammonium groups substituted with a linear or branched alkyl group or linked with a linear or branched alkylene group, a cyclic
quaternary ammonium group or a heterocyclic aromatic quaternary cation group which may be substituted with a linear or branched
alkyl group, M represents a transition metal, L represents a ligand and Q represents an arbitrary counterion equilibrated
stoichiometrically with a charge of the compound.
