Morphological Control of Deposits from a Gaseous Mixture of Allyltrimethylsilane and Iron Pentacarbonyl
Search this article
Under UV light irradiation, a gaseous mixture of allyltrimethylsilane (2-propenyltri- methylsilane) (ATMeSi) and iron pentacarbonyl (Fe(CO)5) produced crystalline deposits as the major product in addition to a small amount of sedimentary aerosol particles. The crystalline deposits were mainly composed of Fe(CO)5 photo-products, and they grew on glass and copper substrates during UV light irradiation. A gaseous ternary mixture of ATMeSi, Fe(CO)5, and carbon disulfide (CS2) produced sedimentary aerosol particles as the major product. FT-IR spectrum of the sedimentary aerosol particles showed the characteris- tic bands ascribed to photo-products from ATMeSi, Fe(CO)5, and CS2, and chemical species of the sedimentary aerosol particles were different from those of the deposits produced from the gaseous binary mixture. With decreasing partial pressure of CS2, particles deposited on the substrate tended to melt and collapse in each other, and finally formed a film after prolonged UV irradiation. Photochemical reactions induced from CS2 molecules were responsible to form aerosol particles.
