Abstract

An electroactive tetrathiafulvalene (TTF)-functionalized amphiphile 1 was designed and synthesized to investigate its self-assembling behavior in water. Dynamic light scattering (DLS), (1)H NMR, fluorescence spectrum, and cryogenic transmission electron microscopy (cryo-TEM) studies revealed that amphiphile 1 can form micelle-like aggregates via direct dissolution into water, and the micellar architectures could be disrupted either by addition of chemical oxidant Fe(ClO(4))(3) or by complexation with electron-deficient cyclobis(paraquat-p-phenylene) tetracation cyclophane (CBPQT(4+)) to release encapsulated hydrophobic dye Nile Red from the interior of micelles.

摘要

一种四硫富瓦烯（TTF）功能化的两亲分子 1 被设计和合成，以研究其在水中的自组装行为。动态光散射（DLS）、（1）H NMR、荧光光谱和低温透射电子显微镜（cryo-TEM）研究表明，两亲分子 1 可以通过直接溶解在水中形成胶束状聚集体，并且胶束结构可以通过加入化学氧化剂 Fe(ClO(4))(3)或与缺电子的环对苯撑对苯二醌四阳离子环番（CBPQT(4+））络合而被破坏，从而将包封的疏水性染料尼罗红从胶束内部释放出来。
