Biscationic bicephalic (double-headed) amphiphiles with an aromatic spacer and a single hydrophobic tail.

We report the synthesis and aggregation studies of a homologous family of biscationic "bicephalic" amphiphiles. Each of has a linear alkoxy chain and two trimethylammonium bromide headgroups connected to a benzene ring. Krafft temperatures (T(K)) in water were determined by differential scanning calorimetry (DSC) and conductivity.
