Control of the surface chemistry and morphology of chalcogenide materials, which are highly polarizable, is a very interesting challenge as it might lead to breakthroughs in various fields such as electrochemistry, catalysis, and gas‐phase separation. With this in mind, a new approach to synthesize structured Ge‐based chalcogenide products has been investigated. It involves the use of tetraethoxygermanium (TEOG) and thioacetamide with an ionic liquid (IL) as structuring agent. This innovative synthesis process has two main advantages: it is performed under soft conditions, and it also enables the morphological control of the obtained hybrid organic–GeS2 particles. In the absence of the IL, the synthesis leads to an agglomeration of nanospheres, whereas the introduction of the ionic liquid leads either to microspheres or to gypsum rosette‐like particles. It has been clearly highlighted that the morphology of the hybrid organic–GeS2 particles strongly depended on the nature of the cationic part of the IL.

“…Dicationic and tricationic ILs expand the horizon of applications for ionic liquids. [34][35][36] Crystal structures of some compounds belonging to this class have also been determined by Anderson et al 27 ILs are also known to aggregate at very small concentrations and hence are useful as surfactants. A systematic study on monocationic and dicationic imidazolium bromide ILs with a tetradecyl chain has shown that the dicationic compound is thermally more stable and also possesses a significantly lower CMC (about 200 times less).…”

The structure and organization in an aqueous solution of a gemini surfactant, the dicationic ionic liquid 1,3-bis(3-decylimidazolium-1-yl) propane bromide, and its vapor-liquid interface have been studied using molecular dynamics simulations at room temperature. Starting from a uniform distribution of cations, the system is found to spontaneously evolve forming cross-linked cationic micellar aggregates. Alkyl tails are typically found buried inside the aggregates to minimize their unfavorable interactions with water, whereas the polar head groups are present at the micellar surfaces, exposed to water. Anions are found throughout the solution and are not strongly bound to the cations. Cationic micellar aggregates exhibit an interesting behavior: interconnection mediated by head groups, a phenomenon which is not observed in monocationic ionic liquid solutions. The structure of the vapor-liquid interface of the solution, the structure of the micellar aggregates, and the distribution of counterions are also discussed.

“…Ionic liquids (ILs) are a class of organic molten salts consisting of only cations and anions [1]. In recent years, ILs have extensive applications because of their unique physicochemical properties such as negligible vapor pressure, high thermal stability, high thermal conductivity, wide electrochemical window and low melting point, etc.…”
