Reverse micellar aggregates find wide range of applications in various areas of science and technol. There exists a continuous demand in replacing the interfacial surfactant mols. with various nonconventional amphiphiles. Ionic liquid-like surfactants (IL-surf) constitute a class of such mols. that are being researched extensively. Here, we have formulated several water/IL-surf/oil microemulsions by optimizing the core droplet size with varying oil phase. The best composition of water/[BMIM][AOT]/IPM ([BMIM][AOT]: 1-Butyl-3-methylimidazolium dioctyl sulfosuccinate; IPM: Iso-Pr myristate) was then analyzed in details through exptl. and computer simulations. Our results from DLS measurements suggest a structural transition from spherical aggregates in the parent water/[Na][AOT]/IPM solution to cylindrical droplets in the IL-surf based system. The Raman and ATR-FTIR spectral anal. suggest a variation in microstructure of the water/oil interface due to the differential interaction of the counterions with AOT headgroups and water. Mol. dynamics simulation results provided the direct image of the interface showing structured vs. uneven water/oil interface in [Na][AOT] vs. [BMIM][AOT] RMs, where larger [BMIM] cations weakly bind with the AOT headgroups due to its low charge d. Finally, an application of this IL-surf based formulation was tested by performing Heck cross-coupling reaction that showed significantly higher yield at milder reaction conditions.
