Phthalocyanine Nano Colloids in Water Prepared by Reprecipitation Method

Abstract

The syntheses of peripherally tetra-substituted nickel(II), copper(II), zinc(II), and metal-free, phthalocyanines containing 4-aryl (4-phenylsulfanyl, 4-phenylsulfinyl, and 4-phenylsulfonyl) and 4-alkyl (4-iso-amylsulfanyl, 4-iso-amylsulfinyl, and 4-iso-amylsulfonyl) groups were demonstrated to investigate water-dispersible phthalocyanine colloids fabricated by a conventional reprecipitation method. Dynamic light scattering measurements revealed that the prepared colloids were monodispersive.
