Benzene, (trimethoxysilyl)-: ACTIVE
Applications
UsesTMPS can also be used in the preparation of polytrimethoxyphenylsilane (PTMS) that facilitates the removal of graphene after chemical vapor deposition (CVD). Molecularly imprinted sol gels can be synthesized by using TMPS for the fabrication of localized surface plasmon resonance (LSPR).
UsesAn organosilicate compound for nanoelectronics and material science research.
UsesPhenyltrimethoxysilane is used for nanoelectronics and material science research. It is used as crosslinking agent for silicone resin and to produce polymer organic silicon compound.
General DescriptionTrimethoxyphenylsilane (TMPS) is an organotrialkoxysilane that is used as a functional monomer in the sol-gel processing.
Preparation methods
PreparationA phenyllithium solution was slowly added dropwise to 60 mL of tetramethoxysilane and reacted for 1 h at a temperature of 0–20 °C. The dropping rate of phenyllithium was controlled at 1.5–2 mL/min. Solid-liquid separation was then performed, and the filtrate was heated to 90–110 °C and distilled under reduced pressure to obtain 6.17 g (0.0312 mol) of a colorless or pale yellow transparent liquid, which was Trimethoxyphenylsilane. Gas chromatography analysis showed its purity to be 97%.
