2(3), 9(10), 16(17), 23(24)-tetrakis[(3-mercapto)propoxy] phthalocyaninate zinc (II)/gold nanoparticle conjugates: Synthesis and photophysical properties

Novel stable zinc (II) thiol-phthalocyaninate gold nanoparticle nanoconjugates (PcS-AuNP) with a reproducible and homogeneous distribution size of 16 ± 4 nm were efficiently prepared by means of a ligand exchange reaction. The nanoconjugates were characterized by TEM, DLS, FT-IR and UV–vis. PcS-AuNP...
