有机笼型分子具有特定的分子内空腔与良好的溶解性，已将孔材料的研究推上了新的高度，但结构不稳定、合成成本高、功能化修饰难等缺点却限制了其进一步应用。本项目以具有聚集诱导发光特性的四苯乙烯衍生物为构筑单元，利用简单经济的芳烃亲核取代反应，一步合成以稳定的芳醚键为连接单元、具有荧光性能的三环氧杂杯芳烃笼型分子，实现结构稳定的有机笼型分子的简单、经济、功能化合成。该笼型分子能通过改变构筑单元或后修饰的策略，调控分子内/外孔道与气体分子尺寸相匹配并改善笼型分子与气体分子间的相互作用力，实现气体分子的选择性吸附。同时，利用其良好的溶解性，通过掺杂的方式制备笼型分子/高分子复合物膜，可实现气体分子的选择性分离。另外，借助荧光分析技术，有望实现对芳香化合物吸附过程的可视化监测。项目通过笼型分子的设计与合成、结构与孔性能的构效分析、气体的吸附分离及吸附过程的可视化研究，为发展新型有机笼型分子孔材料奠定基础。

With the characteristics of good solubility and inherent internal voids, organic cages have attracted considerable attentions and have been recognized as one of the most important directions in porous materials. However, the structure instability, high synthetic cost and functional difficulties for cages are potential drawbacks for certain applications. . In this project, we are going to use tetraphenylethylenes as building blocks to construct fluorescent tricyclooxacalixarene cages by one-pot nucleophilic aromatic substitution (SNAr) reactions. These resultant cages bear size-controllable intra-/inter- molecular voids by changing the size of building blocks or post-modification to match the different gas molecules or improve the interactions between cages and gas molecules, and therefore selectively adsorb gases. With good solubility, these cages also can be used in cage/polymer composite membranes for gas separation. Moreover, visible detection of the absorption process for aromatic compounds might be realized by fluorescent analytic techniques. . This project covers synthesis of tricyclooxacalixarene cages and evaluation of their gas adsorption ability, which may lay a foundation for the development of novel porous materials based on organic cages.
