This paper reports a small family of cationic surfactants designed to bind polyanions such as DNA and heparin. Each molecule has the same hydrophilic cationic ligand and a hydrophobic aliphatic group with eighteen carbon atoms with one, two, or three alkene groups within the hydrophobic chain (C18‐1, C18‐2 and C18‐3). Dynamic light scattering indicates that more alkenes lead to geometric distortion,...
The anion binding ability of two ferrocenoyl amide derivatives with bulky branched substituents has been determined. NMR titration experiments indicated that in each case, the ability of these molecules to bind anions at the core through hydrogen bonding was poor as a consequence of the steric bulk of the substituents. Electrochemical experiments, however, indicated that anion binding could occur...
