Physical properties of giant molecules are intimately dependent upon their primary chemical structures and molecular topologies and thus, precise controls of these structures and topologies are an important pursuit in developing new functional materials. In this paper, we report the rational molecular design and cascading “click” synthesis of three types of polyhedral oligomeric silsesquioxane (POSS)-based asymmetric giant gemini surfactants (AGGSs) including (1) consisting of two polymer tails differing in chain lengths and two identical heads, (2) having two distinct functional heads and two similar tails, and (3) possessing two tails of different lengths and two distinct head groups. The syntheses were achieved in a convenient, efficient, and modular way, allowing the precise control and rigorous tuning of both of polymer tail composition and POSS surface chemistry in these AGGSs. The synthetic processes can be rapidly accomplished within about 5 hours and only require non-chromatographic purification. Our study expands the scope of synthetically available giant surfactants along with the route of macromolecular structure evolution of giant molecules inspired by further decreasing the symmetry of POSS-based giant molecules using “click” chemistry
