General description

Hexamethyldisilazane (HDMS) is an organoslicon compound. HDMS is a colorless liquid used as a reagent and precursor in organic synthesis and organometallic chemistry. It is also used as a sol-gel precursor to fabricate thin films for semiconductor devices.

Application

Hexamethyldisilazane can be used:
  • As a precursor to fabricate multilayer quantum dot light-emitting diodes.
  • To modify dielectric surfaces of organic thin film transistors.
  • To fabricate superhydrophobic coatings on epoxy resins.
  • For the silylation of alcohols and phenols.
