核磁共振弛豫,自扩散以及2DNOESY谱研究结果表明:双子表面活性剂16-4-16溶液在形成胶束的过程中,联结基团及其邻近的碳氢链质子形成胶束的壳层,而距离离子头较远的疏水质子位于胶束的内部.与对应的单链的表面活性剂CTAB相比,其分子运动更受限制.2DNOESY谱显示联接基团及临近的碳氢链的质子间有较强的交叉峰,表明形成胶束时,分子在联结基团附近堆积的较为紧密.由2DNOESY谱计算得到的质子间距与HYPERCHEM模拟值有偏差,表明这些强交叉峰是分子间相互作用的结果,并且对应质子对在双子表面活性剂16-4-16分子中位于邻近的区域.因此我们推测, 双子表面活性剂16-4-16分子在球形胶束中形成特殊的排列方式.
NMR relaxation, self-diffusion and 2DNOESY spectra results show that: the gemini surfactant 16-4-16 solution in the formation of micelles, the coupling group and its adjacent hydrocarbon protons form a shell of micelles, While the hydrophobic protons far from the ion head are located inside the micelles and have more limited molecular motion than the corresponding single-chain surfactant CTAB.2DNOESY spectrum shows the intermolecular intermolecular bond between the linker and the adjacent hydrocarbon chain There was a strong cross peak, indicating that when the micelles were formed, the molecules were more closely packed in the vicinity of the linking group.The calculated proton spacing from the 2DNOESY spectra deviated from the HYPERCHEM simulation values, indicating that these strong cross peaks are intermolecular interactions As a result, and the corresponding proton pairs are located in the adjacent region of the Gemini surfactant 16-4-16 molecule, we speculate that the Gemini surfactant 16-4-16 molecule forms a special arrangement in the spherical micelles.
