Starch alkyl triethanolammonium chloride derivatives and their metal complexes (Cu 2+ , Co 2+ and Fe 3+ ) were prepared and characterized using elemental analysis, FTIR, and 1 H‐NMR spectra. The synthesized compounds were evaluated as antimicrobial agents against different microorganism including bacteria (gram +ve and gram −ve) and fungi. The effect of the chemical structure of the targeted cationic surfactants was discussed based on the surface parameters including surface tension and critical micelle concentration (CMC). Also, the effect of the structure of these surfactants and their metal complexes of Cu 2+ , Co 2+ and Fe 3+ on the cell membrane is discussed as well as their potent action on the targeted bacteria and fungi.
