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.
