Grafting and polymer formation on silicon from unsaturated Grignards: II. Aliphatic precursors

Article Abstract:

A combination of photoluminescence, infrared and X-ray photoelectron spectroscopy is used to study the anodic decomposition of unsaturated Grignards at a hydrogenated silicon electrode, which result in the formation of polymers with broken bonds of the aliphatic precursors. The analysis reveals that the polymers can be highly contaminated by the attack of the ethynyl radicals, which can be avoided by using appropriate solvents, hence making it useful for applications.
