“…Very recently [ 153 ], we performed a complementary study of both imim-DEHP/biocompatible (IPM and ML) RMs, employing absorption and emission spectroscopy as techniques. Two molecular probes, 3,6-bis (dimethylamino) acridinium bis-(2-ethylhexyl) phosphate (AOBH-DEHP) and N,N,N′,N′-tetramethylethylenediamine copper(II) acetylacetonate tetraphenylborate ([Cu(acac)(tmen)][B(C 6 H 5 ) 4 ]), were used.…”

In this review, we deal with the formation and application of biocompatible water-in-oil microemulsions commonly known as reverse micelles (RMs). These RMs are extremely important to facilitate the dissolution of hydrophilic and hydrophobic compounds for biocompatibility in applications in drug delivery, food science, and nanomedicine. The combination of two wisely chosen types of compounds such as biocompatible non-polar solvents and ionic liquids (ILs) with amphiphilic character (surface-active ionic liquids, SAILs) can be used to generate organized systems that perfectly align with the Green Chemistry concepts. Thus, we describe the current state of SAILs (protic and aprotic) to prepare RMs using non-polar but safe solvents such as esters derived from fatty acids, among others. Moreover, the use of the biocompatible solvents as the external phase in RMs and microemulsions/nanoemulsions with the other commonly used biocompatible surfactants is detailed showing the diversity of preparations and important applications. As shown by multiple examples, the properties of the RMs can be modified by changes in the type of surfactant and/or external solvents but a key fact to note is that all these modifications generate novel systems with dissimilar properties. These interesting properties cannot be anticipated or extrapolated, and deep analysis is always required. Finally, the works presented provide valuable information about the use of biocompatible RMs, making them a green and promising alternative toward efficient and sustainable chemistry.

“…Since the early ‘80s, the formation of micelles in ILs took on relevance. Studies have been reported about these types of liquids used as a dispersing phase in micellar systems, , such as a polar solvent confined in reverse micelles. ,− In some studies, PILs are implemented as molecular probes to monitor reverse micelles. ,, Despite the versatility of these newly designed solvents, the greater limitation that ILs can have is the poor solubility of many solutes. Given this situation, it can be overcome by adding conventional cosolvents, taking into account that such an addition will tune the properties of the ILs as solvents.…”

Deciphering Solvation Effects in Aqueous Binary Mixtures by Fluorescence Behavior of 4-Aminophthalimide: The Comparison Between Ionic Liquids and Alcohols as Cosolvents

Ionic liquids (ILs) have received attention for many years due to them being very promising as green solvent substitutes, but they are not fully understood, especially their behavior dissolved in other solvents, for example, water. Thus, the goal of this contribution is to show insight into the different IL− water mixtures interaction. In this way, two protic ILs (PILs), ethylammonium nitrate (EAN) and 1-methylimidazolium acetate (MIA), mixed with water were investigated. To study the PILs− water interaction, the unique spectroscopical behavior in water of the molecular probe 4-aminophthalimide (4-AP) was used. 4-AP emission spectra show hypsochromic shifting by changing the excitation wavelength and, using time-resolved spectroscopy, can be detected by a blue shifting with time. Also, the water mixture of an aprotic IL, 1-methyl-3-butylimidazolium tetrafluoroborate (bmimBF 4 ), and three alcohols, methanol (MeOH), 2-propanol (2-PrOH), and t-butanol (t-BOH), were investigated for comparison. Our results show that the water−ILs interaction is dominated by the size of the IL components, in particular, the cation size. Thus, in MIA−water and bmimBF 4 −water mixtures, 4-AP is mostly solvated by the IL, even at a low IL molar fraction, as in the t-BOH−water mixture. This finding is especially interesting when ILs−water mixtures are used as a solvent in an organic reaction, where it may call attention to water probably not being the solvent that is interacting with the reactants.
