Complexes of zirconium and hafnium with substituted phthalocyanines
The syntheses and electronic spectra of complexes of zirconium and hafnium with halo-, tert-butyl-, nitro-, and amino-substituted phthalocyanines are described. The nature and location of the substituents are shown to affect the electronic absorption spectra. The changes in the spectra of the synthesized complexes on going from DMF to H2SO4 solution are analyzed.
