We report an important and useful method for preparing ω-sulfonated polystyrene-stabilized cadmium sulfide (CdS) nanoclusters. The ω-sulfonated polystyrene (M n = 5000 g/mol) was prepared successfully through chain-end sulfonation of poly(styryl)lithium using 1,3-propanesultone; the resulting polymer was used successfully as a polymeric stabilizing agent for the preparation of semiconductor CdS nanoclusters by reduction of cadmium acetate in a mixture of toluene and methanol (9∶1, v/v). The nanoclusters that formed were characterized by a combination of transmission electron microscopy, X-ray diffraction, and UV/Vis spectroscopic analysis. The ω-sulfonated polystyrene-stabilized CdS nanoclusters synthesized in this study exhibited the cubic phase (zinc-blende phase) structure in the range of 2∼8 nm.
