Abstract
Room temperature ionic liquids (RTILs) are the organic analogues of inorganic molten salts with melting temperature < 100oC.[1] Being ionic in nature, these compounds are versatile in terms of solvent properties such as low volatility, high thermal stability, wide liquid range and good solvating ability. In view of flexibility of choice of cations or anions, RTILs can designed as low viscosity media suitable for self-assembling of amphiphile molecules or also can also be designed as surfactants by incorporating amphiphilic character in either cation or anion or in both the constituents. Therefore, with extraordinary properties it has been possible to include RTILs as media or as a surfactant or both for construction of colloidal formulations/self-assembled structures. Such structures are highly thermally stable and can be used as templates for many applications such as nanoreactors for preparation of shape/size controlled nanomaterials/quantum dots and their hybrid materials for applications such as novel light harvesting materials with enhanced quantum efficiency. The presentation will focus on construction of a novel all ionic liquid based microemulsion system, its characteristics and application for materials preparation in a recyclic manner.
