Descripción

General description

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.

Application

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.

Promueve la O-alquilación eficiente de los alcoholes para formar carbonatos de alquilo mixtos.
