The structure of microemulsions prepared by the anionic gemini surfactant didodecyl diphenyl ether disulfonate (C12-DADS) was investigated by a solvatochromic probe and nuclear magnetic resonance (NMR) diffusion measurements. The NMR measurements indicate the presence of bicontinuous and oil-in-water microemulsions depending on microemulsion composition. The absorbance spectra of the solvatochromic probe, Nile red, indicate the solubilization of the probe in different sites, in agreement with the NMR findings. It was also found that the microemulsions were capable of dissolving the hydrophobic probe, Nile red, up to four times better than expected if it were simply dissolved in the toluene phase.
通过溶剂化显色探针和核磁共振（NMR）扩散测量研究了由阴离子双子表面活性剂二（十二烷基）二苯醚二磺酸盐（C12-DADS）制备的微乳液结构。NMR测量表明，根据微乳液组成，存在双连续和水包油微乳液。溶剂化显色探针尼罗红的吸收光谱表明该探针在不同位置的增溶情况，这与NMR结果一致。还发现，微乳液溶解疏水探针尼罗红的能力比将其简单溶解在甲苯相中时预期的要好四倍。
