摘要:
                                Oxidative coupling of silyl monomers containing phenylene units was performed electrochemically and chemically using FeCl3 as oxidant. 2,5-Trimethylsilyl-1,1-dihexoxybenzene led to poly (2,5-dihexoxyparaphenylene) with a degree of polymerization higher than the one obtained upon oxdative coupling of non silyl monomers. The coupling reaction was however moderately improved in the case of 3,6-bis-dimethylsilyl(N-n-butylcarbazole). The role of the silyl Substituents during the oxidative polymerization is discussed.
