Well‐Organized CdS/C 60 in Block Copolymer Micellar Cores

CdS nanoparticles of 4.5 nm diameter were synthesized in poly(2‐vinylpyridine) micellar cores which were obtained by solvating a polystyrene‐ block ‐poly(2‐vinylpyridine) block copolymer in polystyrene‐selective toluene. Then, a C 60 ‐toluene solution was dispersed into the CdS micelle solution with stirring. This led to the well‐defined organization of two different nanoparticles; specifically: a CdS NP decorated by several/dozens of C 60 molecules, because C 60 molecules were strongly coordinated with pyridine molecules in the micellar cores by charge‐transfer complexation C   60 δ− –P2VP δ+ . A harmoniously organized CdS/C 60 micellar structure was clearly verified by transmission electron microscopy. Fluorescent quenching of CdS nanoparticles, which was strongly affected by neighboring C 60 molecules, was observed.
