Abstract

AbstractIn this work, 1‐halo‐3‐(cyclohexyloxy)propan‐2‐ol (3a/3b) were reacted with N‐methylimidazole (4) or pyridine (5) to yield the respective 3‐(3‐(cyclohexyloxy)‐2‐hydroxypropyl)‐1‐methyl‐1H‐imidazol‐3‐ium (6a/6b) or pyridinium (7a/7b) surface‐active ionic liquids (SAIL). The self‐aggregation behavior of these ionic liquids (IL) was evaluated by conductometric and tensiometric methods. The thermal stability and size of the micelles were determined by thermogravimetric analysis and dynamic light scattering studies, respectively. The investigated IL were found to exhibit very low cytotoxicity as evaluated by MTT (3‐(4, 5‐dimethylthiazol‐2‐yl)‐2, 5‐diphenyltetrazolium bromide) assay on the C6 glioma cell line, indicating that the investigated SAIL can be considered for biological applications like drug and gene delivery. The conventional IL 3‐methyl‐1‐octyl imidazolium bromide (C 8mimBr) was used for comparison in property evaluations.
