基于上缘四脯氨酸修饰杯[4]芳烃和各种紫精客体分子的相互作用,我们构筑了一类新型的二元超分子水凝胶.得到结果显示,在酸性条件下,溴化紫精盐最易于促进四脯氨酸修饰杯[4]芳烃形成水凝胶.并且经落球法测定了所制备水凝胶的凝胶-溶胶转变温度,采用原子力显微镜和扫描电子显微镜表征了水凝胶的微观形态,发现紫精的侧链对水凝胶性质具有显著影响,包括凝胶-溶胶转变温度和微观形态.值得注意的是,该类水凝胶不仅具有优良的电刺激响应性,而且能够通过化学、pH和热等多种因素进行调控.
Based on the interaction between the top four proline-modified calix [4] arenes and various viologen guest molecules, we constructed a new type of binary supramolecular hydrogel. The results show that under the acidic conditions, bromination Violet salt is most likely to promote four proline modified calix [4] arene to form hydrogel, and the gel-sol transition temperature of the prepared hydrogel is determined by the falling ball method, and the hydrogel is characterized by atomic force microscopy and scanning electron microscopy It was found that the side chains of viologen had a significant effect on the properties of hydrogels, including the gel-sol transition temperature and microscopic morphology.It is noteworthy that such hydrogels not only have excellent electrical stimulation responsiveness, And through chemical, pH and heat and other factors to regulate.
