“…The anion most frequently is inorganic, such as nitrate, [8,9,10g] perchlorate, [8,9,10e] dinitramide, [8,9c,10] azide [10g] and tetraazidoborate anion. [11] However, reports are already available that describe analogous salts with organic anions, such as α-cyano-4-hydroxycinnamate, anthraquinone-2-sulfonate, [12] salicylate and lactate, [13] imidazolate and triazolate and tetrazolate.…”

Hexamethylenetetrammonium salts, composed of energetic anions 3,5-dinitropyrazolate, 4,5-dinitroimidazolate, 3,5-dinitro-1,2,4-triazolate, 5-nitrotetrazolate, perchlorate, nitrate and azide, were synthesized and characterized. The structure of N-methyl-hexamethylenetetrammonium 3,5-dinitro-1,2,4-triazolate (6) was confirmed by X-ray analysis. The standard enthalpies of formation for the new salts were cal-

“…For example, different series of liquid crystalline 1‐alkylimidazolium salts (alkyl = 10 ‐ 18 ) were obtained from the reaction of nitric, hydrochloric, and tetrafluoroboric acids with the corresponding 1‐alkylimidazole (Lee et al, ). Pernak et al reported a series of 1‐alky‐ and 1‐alkoxyimidazolium (alkyl = 1 ‐ 12 ) lactates and salicylates that exhibited antimicrobial activities (Pernak et al, ; Pernak and Goc, ). Moschovi et al have recently studied intermolecular and intramolecular interactions in 1‐akyl imidazolium protic IL (alkyl = 2 ‐ 12 ) with bis(trifluoromethanesulfonyl)imide (Moschovi et al, ).…”

New cationic surface‐active ionic liquids (SAIL) were synthesized using 1‐alkylimidazolium cations [CnHim] (n = 8, 10, 12, 14, and 16) with trifluoroacetate ([CF3CO2]) and methanesulfonate ([CH3SO3]) anions as counterions. Their self‐aggregation behavior in water was investigated using electrical conductivity and fluorescence measurements. Based on the obtained results, the critical micellar concentration (CMC), the degree of counterion dissociation, α, the Gibbs free energy of micelle formation, normalΔGmic0, and the mean aggregation number (Nagg) were determined. The analysis of these parameters indicates that these new SAIL exhibit certain improved properties with respect to traditional cationic surfactants. Furthermore, SAIL with [CF3CO2] counterions exhibit lower CMC values than alkyltrimethylammonium bromide (CnTAB)‐type surfactants and their dialkylimidazolium counterparts with the same alkyl chain length. It was demonstrated that, in the studied SAIL, the hydrophobic probe pyrene resides deeper inside the palisade layer of the micelle and the estimated E T(30) polarity values of micellar pseudophase confirm this result. The abovementioned outcomes demonstrate that the 1‐alkylimidazolium cation is suitable to promote aggregation when it is accompanied by the appropriate counterions. Consequently, this contribution becomes a valuable first step toward the potential application of these compounds as a new class of “designed cationic surfactants.”

“…ILs are defined as liquid chemical substances consisting solely of ions: An organic cation and an organic or inorganic anion [ 4 ]. Examples of organic anions are acetates, lactates, salicylates, benzoates, saccharinates, and thiazolanes [ 5 ]. ILs with a thiazolate anion are classified as energetic ionic liquids.…”

“…Chemotherapy is characterized by a selective accumulation of 10 B isotope in rapidly dividing cancer cells [ 35 ]. Studies have shown that microscopic images of analyzed tissues stored in ILs are 10 times more pronounced than in the case of traditional solvents, e.g., formaldehyde [ 5 , 21 ]. This feature may be useful in the future for faster and more precise diagnosis of various inflammatory conditions or pre-motor changes.…”

This review deals with various microbiological activities of ionic liquids, which constitute the first anti-infective defense against multi-drug-resistant bacteria—with a particular emphasis placed on medicine and pharmacology. The quoted data on the biological activity of ionic liquids including their antimicrobial properties (depending on the type of a cation or an anion) and are discussed in view of possible applications in nosocomial infections. Dedicated attention is given to finding infections with the Klebsiella pneumoniae New Delhi strain, Acinetobacter baumannii, and Enterococcus species, which are responsible for the induction of antibiotic resistance in intensive care units. Diagnosis and treatment using current antibiotics is a significant problem in hospital care, and the relevant burden on the health systems of the European Union member states induces the search for new, effective methods of treatment. Ionic liquids, due to their antibacterial effect, can be considered topical and general medications and may provide the basis for treatment to eliminate the antibiotic resistance phenomenon in the future. At present, the number of infections with resistant pathogens in hospitals and outpatient clinics in the European Union is growing. In 2015–2017, a significant incidence of respiratory and bloodstream infections with bacteria resistant to antibiotics from the 3rd generation group of cephalosporins, glycopeptides, and carbapenems were observed. The paper presents examples of synthesized bifunctional salts with at least one pharmaceutically active ion in obtaining a controlled release, controlled delivery, and biological impact on the pathogenic bacteria, viruses and fungi. The ionic liquids obtained in the presented way may find applications in the treatment of wounds and infections.
