Three carbohydrate‐modified polysiloxane bola surfactants (ATPS‐GA) were synthesized using a two‐step method. Their chemical structures were characterized by infrared spectroscopy (FT‐IR) and proton nuclear magnetic resonance spectroscopy ( 1 H NMR). Their surface properties and aggregation properties in aqueous solution were determined using surface tension measurements and transmission electron microscopy (TEM). Surface tension measurement results indicated that the three bola surfactants are under 25 mN m −1 , and much lower than those of conventional hydrocarbon bola surfactants due to the siloxane moiety at the end of the hydrophobic chains. TEM analysis results indicated that the ATPS‐GA can self‐assemble into spherical micelles with a wide range of average diameters from 100 nm to above 600 nm.
