Paper Abstract

Hydropolysilane copolymers have been synthesized by the Wurtz- type reductive coupling of mono and diorganodichlorosilane comonomers with sodium dispersion in a refluxing toluene medium. Post-synthetic modifications of the copolymers have been carried out to improve their photosensitivity to UV/Vis energy, by the substitution of electron-withdrawing groups such as acetate (from mercuric acetate), p-nitrophenol, p-cyanophenol, and p- chlorocinnamic acid. The modified and unmodified copolymers, have been extensively characterized by various spectroscopic techniques such as GPC, FTIR, H-NMR, C-NMR, UV/VIS, etc. The results reveal that, the properties as well as the reactivities of hydropolysilanes are strongly dependent on the types of substituent groups on the Si-Si main chains.
