Applications of functionalized ionic liquids

Ionic Liquids: Synthesis and Applications in Catalysis

“…Although ionic liquids were initially introduced as alternative green reaction media because of their unique physical and chemical properties, today they have marched far beyond this border, showing their significant role in controlling the reaction as catalysts [70][71][72][73][74][75]. Depending upon the functional group attached to the cation and/or anion, the ionic liquid may behave as an acidic, basic, or organocatalyst.…”

Ionic Liquids as Designer Solvents for the Synthesis of Metal Nanoparticles

“…Another category of functionalized ILs includes those which contain certain functional groups that may bond onto metal surfaces, and thus stabilize the formed metal nanoparticles more effectively. This has led to development of a range of new functionalized ILs, which are also often termed as "task-specific ILs" (Davis, 2004;Fei et al, 2006;Lee, 2006;Li et al, 2006;Davis & Wassercheid, 2008). To this end, thiol-containing ILs are particularly notable towards stabilization of metal nanoparticles, as thiols are well-known to interact strongly with metal surfaces.…”

“…Particularly interesting is the observation that ILs can themselves be functionalized to either incorporate metal ions (Iida et al, 2008) or reducing agent (Dinda et al, 2008) within the IL structure. This provides a great deal of flexibility towards facile synthesis and stabilization of metal nanoparticles towards narrow and small size range with a potential ability to control their shape anisotropy (Davis, 2004;Fei el al., 2006;Lee, 2006;Li et al, 2006;Davis & Wassercheid, 2008). However, in our opinion, it is not truly remarkable if one seeks to use functionalized ILs just for the sake of making nanoparticles.…”

Synthesis of novel ionic liquid-supported Schiff bases

“…Owing to these properties, research has been focused on the synthesis of new ionic liquids with functional groups, so called "task-specific" or functionalized ionic liquids, and their applications. [9][10][11] Schiff bases are usually formed by the condensation of a primary amine (or diamine) with an aldehyde. [12][13][14] Numerous reports on the preparation of Schiff bases and their applications have been published.…”
