Abstract
It was established that many crystalline molecular complexes composed of cationic surfactants such as CTAB and several phenolic derivatives were obtained from an appropriate concentrated solution system in which a remarkable viscoelasticity was developed. It is revealed that the molecular complexes have an unambiguous composition of 1:1 molar ratio of surfactants to phenolic additives. The molecular complexes also showed characteristic endothermicity of a degree that suggests the specimens to be single and a pure species. However, through repeated runs the thermal stability of the complexes seemed to be rather poor, as exhibited by a profile change in thermograms of DSC.
