Abstract
(type = abstract)
Long-chain surfactants form micelles when the concentration reaches cmc. Micelles are composed of a hydrophobic core and an interfacial region containing head groups in contact with water molecules and counterions. Recent research shows that the interfacial region plays an important role in micellar properties and structures. The change of composition in the micellar solution shifts the balance of forces and changes the micelle size and shape as a result. Chemical trapping method is applied to estimate the interfacial compositions of micelles. The probe, 16-ArN2+, reacts with the weakly basic nucleophiles in the interfacial region, and the products are analyzed with HPLC. Changes in interfacial concentrations of water and counterions through the sphere-to-rod transitions of CTAB and CTAC solutions have been studied by the chemical trapping method, and the results have been published. In the second chapter of the thesis, the chemical trapping method was applied to long chain micellar solutions DTAB and CTAToS. When counterion salts are added in the surfactant solutions, the counterion concentration in micellar interfacial region increases incrementally. Chapter 3 introduces non-conventional gemini surfactants 12-n-12•2Br (n = 2, 3 and 4) and their simple model bolaform sals 1-n-1•2Br (n = 2, 3 and 4). The twin-tailed structures have rather small 1st and 2nd cmcs comparing to their single-tailed analog DTAB. Single crystal X-ray diffraction technique is used to analyze bolaform salts. Weak hydrogen bonds are discovered in 1-2-1•2Br and 1-3-1•2Br crystals.
