Abstract
AbstractFour cationic gemini surfactants featuring semi‐rigid spacers were synthesized via a two‐step process. The surface‐active properties of these surfactants were investigated through surface tension and electrical conductivity measurement. The thermodynamic parameters of micellization were evaluated from electrical conductivity measurements at temperatures ranging from 293 to 313 K. The aggregation behavior of these synthesized gemini surfactants in water were investigated using dynamic light scattering and transmission electron microscopy. Further, the antimicrobial activities of these synthesized gemini surfactants against both Gram‐positive and Gram‐negative bacteria were also investigated.
