General description

Cesium hydroxide is a strong base that can be used in organic synthesis, as a catalyst, and as an intermediate in the production of cesium compounds.

Application

Cesium hydroxide monohydrate can be used:

  • As a catalyst to prepare unsymmetrical Bis-allyl ethers via dimerization of Baylis-Hillman adducts.
  • As a dopant to fabricate vanadium oxide thin films as a hole extraction layer for perovskite solar cells.
  • As an initiator for ring opening polymerization of monosubstituted oxiranes.
  • As a promoter to synthesize secondary amines via chemoselective N-alkylation.

Methods of Synthesizing Monodisperse Colloidal Quantum Dots

Colloidal quantum dots (CQDs) are semiconducting crystals of only a few nanometers (ca. 2–12 nm) coated with ligand/surfactant molecules to help prevent agglomeration.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
