Electrokinetic properties of metal phthalocyanite nanoparticles

The effect of the nature of the metal in metal phthalocyanites on the electrokinetic potential and рН of the isoelectric point (рН(I)) in suspensions of these substances in NaCl solution (0.1 mol/L) is elucidated. The рН(I) values of unmodified МРс increases in a sequence MnPc < CoPc < СuPc ≈...

Description
Summary:The effect of the nature of the metal in metal phthalocyanites on the electrokinetic potential and рН of the isoelectric point (рН(I)) in suspensions of these substances in NaCl solution (0.1 mol/L) is elucidated. The рН(I) values of unmodified МРс increases in a sequence MnPc < CoPc < СuPc ≈ ZnPc on account of the decreasing effective charge of the coordinated metal ion that corresponds to the Irving–Williams series. The impact of the functional group upon heterogeneous modification of МРс nanoparticles is studied, as well. It is established that the modifying group (the oxygenic properties) exerts a stronger influence on (pH(I)) than the metal nature.
