Trimethoxyphenylsilane (TMPS) is an organotrialkoxysilane with the chemical formula (CH₃O)₃SiC₆H₅ and the CAS number 2996-92-1. It is a clear liquid with a boiling point of 233 °C and a density of 1.062 g/mL at 25 °C. It has a refractive index of 1.468 and a molecular weight of 198.29.
TMPS is a functional monomer that can be used in the sol-gel processing to produce hybrid organic-inorganic materials with phenyl groups. These materials have potential applications in optical, electronic, catalytic, and biomedical fields. TMPS can also be used as a precursor for polytrimethoxyphenylsilane (PTMS), a polysilane that can facilitate the removal of graphene after chemical vapor deposition (CVD). Graphene is a two-dimensional material with exceptional properties that can be used for nanoelectronics, sensors, and energy storage devices.
TMPS is commercially available from various suppliers, such as Merck and Sigma-Aldrich. It can be synthesized by the reaction of phenylsilane with methanol in the presence of a catalyst, such as sulfuric acid or p-toluenesulfonic acid. TMPS is stable under normal conditions, but it can hydrolyze in the presence of water or moisture to form phenylsilanol and methanol. It is also flammable and can cause irritation to the eyes, skin, and respiratory tract. Therefore, it should be handled with care and stored in a cool, dry, and well-ventilated place away from heat, sparks, and flames.
TMPS is a versatile organotrialkoxysilane that can be used for various purposes. It can be used as a functional monomer in the sol-gel processing to produce hybrid materials with phenyl groups. It can also be used as a precursor for PTMS, a polysilane that can facilitate the removal of graphene after CVD. TMPS is a useful compound for researchers and engineers who are interested in exploring the properties and applications of organic-inorganic hybrid materials and graphene.
