Self-assembly and solubilization properties of amphiphilic mono- and bisquaternized derivatives of 1,4-diazabicyclo[2.2.2]octane (mono-CS-n and di-CS-n, where CS cationic surfactant, n=12, 14, 16, 18) was investigated by nuclear magnetic resonance with magnetic field pulse gradient. The influence of Dabco-surfactant structure (head group and length of alkyl chains) on critical micelle concentration and aggregat...
