Taking a natural triterpenoid as the building block, we have regulated a pyridinium-functionalized methyl glycyrrhetate (C4-MGP) into P-type helices in water primarily driven by hydrophobic forces. By analysing their temperature-dependent CD and UV-Vis spectra, these hierarchical chiral assemblies were found to be formed in a cooperative supramolecular polymerization manner.
以天然三萜为构建模块，我们在水中主要通过疏水作用力调节出具有吡啶功能的甲基甘草次酸（C4-MGP）形成 P 型螺旋。通过分析其温度依赖的圆二色谱（CD）和紫外-可见光谱（UV-Vis），发现这些分级手性组装体是以协同超分子聚合的方式形成的。
