General Description
Trimethoxy(octadecyl)silane (OTS) is an important alkylsilane that can form strong covalent bonds with silicon oxide and serves as a potential lubricant for micro electro mechanical systems (MEMS). OTS is largely used for surface chemical modification, modifying silica resulted in an increased charge carrier mobility for a variety of vacuum deposited and solution cast organic semiconductors.
