The early detection of volatile organic compounds (VOCs) is crucial for sustainable development. Improving the binding properties of crystalline materials for special VOC guests is a tough challenge. Herein, by rationally connecting bis-8-hydroxyquinoline groups onto the two sides of the pillar[5]arene, a “synergistic effect” has been introduced into pillar[5]arene-based macrocyclic host (PQ8). The synergistic effect was based on the collaboration of the bis-8-hydroxyquinoline and the pillar[5]arene groups, which endowed the PQ8 with a reversible selective fluorescent response for 2-ethylenediamine (EDA). Moreover, the crystal of PQ8 could act as a reusable material for the detection and adsorption of the EDA vapor.

基于协同效应的柱[5]芳烃基晶体材料结合性能的合理调控及其在荧光检测和1,2-乙二胺吸附中的应用

挥发性有机化合物 (VOC) 的早期检测对于可持续发展至关重要。提高结晶材料对特殊 VOC 客体的粘合性能是一项艰巨的挑战。在此，通过将双-8-羟基喹啉基团合理连接到柱[5]芳烃的两侧，在柱[5]芳烃基大环主体（PQ8）中引入了“协同效应” 。协同效应基于双-8-羟基喹啉和柱[5]芳烃基团的协同作用，这使PQ8具有对2-乙二胺（EDA）的可逆选择性荧光响应。此外，PQ8的晶体可以作为一种可重复使用的材料，用于检测和吸附EDA 汽。
