New amphiphiles with reactive tosylate groups and ionic sulfuric acid half esters based on the rod‐like polysaccharide cellulose were designed via homogeneous tosylation followed by sulfation with the SO 3 ‐pyridine complex in N,N ‐dimethylacetamide. At appropriate degrees of functionalization the polymers are soluble both in water and dimethyl sulfoxide, and they are promising starting materials for self‐organizing systems.
