摘要：Four-arm porphyrinic polystyrenes (TPP-PS) were prepared with well controlled and low dispersity, by reversible addition fragmentation chain transfer (RAFT) polymerization, and their self-assembly morphology with fullerene (C-60) was investigated. Monodisperse nanospheres of porphyrin-fullerene complexes were obtained in organic solvents, which showed morphological changes (shrinkage-swelling) under different parameters (concentration, solvent and polymeric chain length). The optimized parameters gave well controlled and convenient fabrication of monodisperse nanospheres which were confirmed in both solution and dry phases. Optical studies (UV/Vis and fluorescence) confirmed the inter-molecular interactions between porphyrin and fullerene, while transmission electron microscopy gave insight into the morphology of monodisperse nanospheres.
