[Dimerization of aluminum, zinc, vanadium and gallium phthalocyanine-sulfonates in water, aqueous alcoholic solutions and micelles].
The dimerization of Aluminum (III),Vanadium(lV), Gallium(III) tetrasulfonated phthalocyanine (AlTSPc, VOTSPc, GaTSPc) and Zinc(II) bisulfonated phthalocyanine (ZnBSPc) was studied by spectrophotometic method. The dimerization constants KD were calculated from absorbance measurements. The absorption spectra in water, aqueous alcoholic solutions and micelles of phthalocyanine sulfonates aluminum shows the "slow-forming dimer", and VOTSPc, GaTSPc, ZnBSPc show contact dimer formation.
