Unravelling the optical properties and self-assembly behavior of ciprofloxacin in ionic liquid environments: probing the role of cationic residues and counter anions.

This study investigated the interaction of ciprofloxacin (CIP) with three different ionic liquids (ILs) featuring distinct cationic residues (pyrrolidinium, IL, . imidazolium, IL, with bis(trifluoromethylsulfonyl)imide as the counter anion) and counter anions bis(trifluoromethylsulfonyl)imide, IL, . hexafluorophosphate, IL, with imidazolium as the cationic residue) in an aqueous environment.
