Four supramolecular assemblies are fabricated from two pillararene tetramers with aggregation‐induced emission properties (SH and LH) and two different lengths of neutral guests with three binding sites (arms) for pillararene cavities (SG and LG) through host–guest interactions, and their fluorescent behaviors in organic solvent are investigated. SG⊂SH exhibits the largest fluorescent enhancement in chloroform due to supramolecular assembly‐induced emission enhancement, while only LG⊂LH turns into supramolecular gel with stimuli responsiveness owing to their most flexible arms.

基于Pillararene的荧光超分子系统：链长在胶凝中的关键作用

四个超分子组装体由两个具有聚集诱导发射特性的柱状芳烃四聚体（SH和LH）和两个不同长度的中性客体（通过主客体相互作用）形成三个用于柱状芳烃腔（SG和LG）的结合位点（臂）的客体组成。研究了有机溶剂中的荧光行为。SG⊂SH表现出氯仿最大荧光增强由于超分子组装引起的发光增强，而只有LG⊂LH匝成超分子的凝胶与刺激响应性由于它们的最柔性臂。
