EPR of Powder Copper Phthalocyaninate Substituted with Eight Tetraazamacrocycles and Its Nonanuclear Ni2+, Co2+, Zn2+ and Cu2+ Complexes

Abstract

Variations of the electron paramagnetic resonance parameters of the copper phthalocyaninates dye to the paramagnetic and diamagnetic metal ions substituted into the outer cells of eight 12-membered tetraazamacrocycles are found to be very slight and this slight difference is attributed to the electronegativity of the substituted metal.
