Descrizione generale

Cesium carbonate is a mild inorganic base widely used inelectroluminescent devices and organic synthesis. Due to its excellent electroninjection capability, it is used as an interface modifying material in organiclight-emitting diodes (OLED), organic field effect transistors (OFET), organicsolar cells (OSCs), and perovskite solar cells.

Applicazioni

Cesium carbonate can be used as:
  • A cathode buffer layer to enhance device stability and power conversion efficiency in polymer solar cells.
  • A precursor to prepare alkali-based electrolyte for selective reduction of CO2 by electrocatalysis.
  • A base in many organic transformations such as C, N, O alkylation, and arylation reactions.
Promotes the efficient O-alkylation of alcohols to form mixed alkyl carbonates.
