mineralizing agent and basic media to synthesize zeolites. In addition, different combinations of these reagents were tested, and different zeolitic topologies were obtained [1; 8]. At the same time, zeolitic scientists observed that changing the cation of the hydroxide in the same synthesis (e.g., replacing sodium hydroxide with potassium hydroxide) forced variations in the crystal parameters of the final material, even to the point of synthesizing a completely different topology. This behavior justified the incorporation of the concepts _templates_, _structure-directing agents_ (SDAs), and _pore-fillers_, which were differentiated based on the type of interactions present in the structure [9]. Over time, scientists began to study the addition of organic compounds to the synthesis procedure [10; 11; 12; 13; 14]. However, what popularized these organic compounds was the synthesis with HF (hydrofluoric media) to replace the hydroxides. Zeolites such as pure silica sodalite, ZSM-5, silicalite-1, and silicalite-2 were obtained. Since then and until now, these compounds have been studied for synthesis applications. A very interesting type of organic compound is ionic liquids. These molecules are characterized by a low melting temperature and low vapor pressure [15]. It is precisely these properties that justify their application for synthesizing zeolites. Ionic liquids can act as an SDA and solvent. Then, we can use ionic liquids in hydrothermal synthesis with water as the solvent and, also, in a new type of synthesis method, the ionothermal, in which the ionic liquid role is twofold, an SDA and a solvent [16; 17]. This mini-review is focused on that first situation, but we recommend reading other reviews or book chapters, such as those from the [PERSON] group, regarding the second type of synthesis [18; 19]. Among the various ionic liquids there are the imidazolium derivatives, which are usually synthesized via the quaternization of one of the Ns of the corresponding imidazole derivative [20; 21]. These compounds have a certain degree of hydrophobicity, which helps to explain the role they represent in synthesis, as for example described in the articles by [PERSON] et al. and [PERSON] et al. [22; 23]. Ionic liquids are also easy to use and possible to recycle. Ionic liquids possess diverse possible substituents and, as a consequence, wide synthetic possibilities [24; 25; 26]. In the first example, an ionic liquid was used to synthesize an extra-large pore zeolite by adjusting the supramolecular chemistry, possibly thanks to the use of imidazolium derivatives. Subsequently, the second example showed how an imidazolium derivative helped produce a high silica zeolite Y thanks to the interactions of the OSDA-framework. The last example described a fast ZSM-22 synthesis procedure. For these reasons, great interest has been generated. The use of ionic liquids in the synthesis of zeolites began with the group of Prof. Dr. [PERSON], and they currently continue to carry out studies in this regard [27; 28]. Ultimately, these materials led to the synthesis of more germanosilicates using imidazolium derivatives, as reported by Prof. Dr. [PERSON]'s group and Prof. Dr. [PERSON] and collaborators [6; 29; 30], and in turn, these ionic liquids were studied by Prof. Dr. [PERSON] group to achieve a new synthesis route: ADOR (assembly-disassembly-organization-reassembly) [31; 32]. Through this process, some of the hypothetical structures that were once called unfeasible have been synthesized, which was not possible through traditional methodologies [33]. Returning to the pure silica composition, we find that Prof. Dr. [PERSON]'s group also excels in this type of synthesis, managing to stabilize the chiral topology of STW, which is also thanks to the use of the hydrofluoric medium [7]. Afterwards, we will describe a study on introducing aluminum into this structure, which was performed at LABEMOL [34]. Note that further studies about the germanosilicate STW zeolite were published by Prof. Dr. [PERSON]'s group [35; 36].
