Ionic Liquids (IL's) are mixtures of cations and anions forming salts that are liquid at room temperature, remaining in that phase even at high temperatures. The first ionic liquid was reported in 1914 by Paul Walden, synthesized by neutralization of ethylamine with concentrated nitric acid, resulting in ethylamonium nitrate salt, [EtNH 3 ][ NO 3 ]. In the 1990s, it was discovered that IL's can be stable in air and aqueous conditions, and since then, the interest in this type of systems has increased exponentially in both academia and industry. A number of possible applications has been investigated, including (but not limited to) electrolytes for batteries, lubricants, organic solvent substitutes, biocatalysis, etc. The synthesis of ionic liquids can be carried out by combining a (generally) asymmetric organic cation with an inorganic anion. This means that having a single cation, it is possible to combine it with one of the numerous anions available, forming a different ionic liquid with each combination. One of the most investigated cations is imidazolium [Im + ] due to its particular properties such as the ease with which the alkyl chain length can be modified on the nitrogen atoms of the [Im + ] ring, being an interesting option to develop more solvents by combining it with different anions, using the same basic structure for the cation. The versatility of [Im + ] cation is one of the reasons why [Im + ]-based IL's are some of the most employed IL's in industrial applications. The vast possibilities for synthesizing ionic liquid pairs results in the quandary of determining these compounds' properties at a reasonable time and cost. Computer simulations have become a useful tool in studying and determining the properties of ionic liquids as well as predicting specific ionic liquids with desired properties. Molecular dynamics (MD) simulations to investigate IL's can be carried out using non-polarizable or polarizable force fields. The latter option provides an approach that explicitly includes the electronic polarization contribution, which may play an important part in these systems. We have developed an all-atom polarizable IL potential based on the AMOEBA force field, termed AMOEBA-IL. AMOEBA-IL uses distributed multipoles obtained from the Gaussian Electrostatic Model (GEM-DM). GEM-DM has been shown to be transferable for the development of atom-centered multipoles for the AMOEBA force field. So far, AMOEBA-IL has been limited to a small number of cations and anions due to the costly parametrization procedure, which involves the determination of distributed multipoles for each molecule. We have shown that AMOEBA-IL can accurately reproduce bulk properties. Additionally, AMOEBA-IL has been shown to predict properties for previously uncharacterized pairs. Specifically, for spirocyclic pyrrolidinium [sPyr + ] and [BF 4 -], calculations with AMOEBA-IL prior to the experimental synthesis of the ions predicted the melting point for this ion pair within 2% of the subsequently calculated value. In this contribution, we present a new method for the parametrization of imidazoliumbased AMOEBA-IL cations consisting of transferring the parameters of specific fragments of previously parametrized groups of the alkyl chain of a relatively small imidazolium cation The remainder of the paper is as follows: in the next section we describe the details of the previous parametrization approach, the new method to transfer the required parameters to generate arbitrary alkyl chains in imidazolium cations, and details of the MD simulations and analyses. Subsequently, results for gas-phase and bulk calculations are presented, and compared with reference data from the literature for selected imidazolium-based IL combinations, followed by concluding remarks.
