TiO 2 is a commonly used material in the electron transport layers (ETLs) of perovskite solar cells (PSCs) but its defects restrict the development of PSCs. In this study, cesium carbonate (Cs 2 CO 3) was used to modify the TiO 2 ETLs because of its excellent electron injection ability. The new structure of the PSC was FTO/TiO 2 /Cs 2 CO 3 /perovskite …
One of the biggest advantages of cesium carbonate (Cs2CO3) is that it has a higher solubility in most solvents than K2CO3 or Na2CO3. Common Uses: Base for substitution reactions. Procedure excerpt: To a solution of the phenol (0.200 g, 1.07 mmol) in acetone (10 mL) was added the alkyl bromide (0.40 g, 1.2 mmol) followed by Cs2CO3 (1.0 g, 3.1 ...

The presence of cesium carbonate and tetrabutylammonium iodide (TBAI) facilitated efficient O-alkylation of alcohols with alkyl halides, giving rise to the exclusive formation of mixed alkyl carbonates. The cesium effect was also examined comparatively with other alkali carbonates. ... The carbonate formation was enhanced by the use of TBAI as ...

Direct mono-N-alkylation of primary benzylamines and anilines with a wide range of alkyl halides is promoted by a cesium base in the absence of any additive or catalyst. The basicity and solubility of cesium carbonate in anhydrous N, N -dimethylformamide not only enables mono- N -alkylation of primary amines but also suppresses undesired ...
