设计并合成了一种新的水溶性双芳烃双酰亚胺衍生物(CTDI)。CTDI在水溶液中自组装,并通过π-π堆积和疏水相互作用形成超分子纳米纤维。纳米纤维表现出独特的过氧化物酶样催化活性,并且可以在过氧化氢的存在下催化3,3,5,5-四甲基联苯胺(TMB)的氧化还原反应。观察到清晰的测定溶液颜色变化。利用过氧化物酶样的催化特性对H 2 O 2进行灵敏检测和葡萄糖。该测定法显示出极好的灵敏度,并且可以轻松检测到1μM的葡萄糖。还证实了在稀人血样品中的葡萄糖检测,并使用商用血糖仪验证了结果。我们的方法简单,方便,灵敏且选择性强,可以促进与生物和生物医学研究应用有关的葡萄糖感测。

The synthesis of an amphiphilic coronene bisimide (Amph-CBI) and its self-assembly in THF/water through π−π stacking and solvophobic interactions are reported. Spectroscopic and microscopic studies revealed a bilayer like self-assembly of the coronene amphiphile to different kinds of one-dimensional nanostructures, such as nanotubes and nanotapes, which can be controlled by solvent composition.
