| 中文摘要: |
| 双子表面活性剂12-4-12与反式肉桂酸（tCA）由于强烈的静电吸引作用而生成12-4-12/tCA沉淀相。通过偏光显微镜和X射线衍射测定，我们发现12-4-12/tCA沉淀相具有六角和层状的复合晶体结构。在365 nm紫外光照射下，12-4-12/tCA沉淀相会逐渐溶解，依次经历晶体—囊泡—蠕虫状胶束的转变。我们对12-4-12/tCA沉淀相的光响应溶解及聚集体结构转变机理进行了讨论。 |
| 英文摘要: |
| 12-4-12/tCA precipitates are formed due to the strong electrostatic attraction between gemini surfactant 12-4-12 and trans-cinnamic acid (tCA). We have used polarized optial microscope and X-ray diffraction to find that 12-4-12/tCA precipitates have composite structure of hexagonal and lamellar crystals. Under the irradiation with ultraviolet light, 12-4-12/tCA precipitates can gradually dissolve, and successively experience the transformation of crystals-vesicles-worm-like micelles. We have discussed the mechanisms for the photoresponsive dissolution and aggregation structure transformation of 12-4-12/tCA precipitates. |
