Abstract:
Ionic liquid-functionalized amphiphilic Janus chiral salen TiIV catalysts were prepared by partial hydrophobic modification of silica with a chiral salen TiIV complex through an imidazolium ionic liquid (IL) linker. By optimizing their hydrophobic/hydrophilic balance, the IL-functionalized JNP materials exhibited excellent interfacial activity, significantly accelerating asymmetric sulfoxidation in water through the formation of stable Pickering emulsions. Moreover, catalyst recovery was readily achieved using centrifugation.

Ionic Bonds
When atoms gain or lose electrons to achieve a more stable electron configuration they form ions. Ionic bonds are electrostatic attractions between ions with opposite charges. Ionic compounds are rigid and brittle when solid and may dissociate into their constituent ions in water. Covalent compounds, by contrast, remain intact unless a chemical reaction breaks them.

Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...
