A photo-responsive host-guest molecular recognition between a cationic pillar[6]arene host and an arylazopyrazole derived guest was established. Based on this novel recognition motif, a photo-controllable supra-amphiphile was constructed. The spontaneous aggregation can be reversibly controlled by irradiation with UV (365 nm) and green light (520 nm), leading to a switch between spherical nanoparticles and vesicle-like aggregates.
建立了阳离子柱[6]芳烃主体与芳基偶氮吡唑衍生客体之间的光响应主客体分子识别。基于这种新型识别基序，构建了一种光控超两亲分子。通过用紫外线（365nm）和绿光（520nm）照射，可以可逆地控制自发聚集，从而实现球形纳米颗粒与囊泡状聚集体之间的转变。
