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 due 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.
