Abstract
A new series of polycarbosilanes [(PhCH2)SiCH3Cl, Poly B] was designed by chlorinating cleavage reaction of silicon–naphthyl in polycarbosilane. The 1H spectra of poly B revealed that the SiCH2 and the SiCH3 protons peak were up-field shifted compared with the type [(PhCH2)SiCH3Np, Poly A] polycarbosilane. Grafted polycarbosilane was synthesized with poly ethylene glycol (PEG) by nucleophilic substitution of the chloride substituents on the polycarbosilane. The aggregation behaviors of graft copolymers were investigated by dynamic light scattering and fluorescence at 25 °C in aqueous solutions of different polyethylene glycol (PEG) substituent.
