瓜环化学中主客体化学及配位化学已为人熟知；但基于瓜环正电性外壁作用的化学还未受到足够重视。本项目根据瓜环正电性外壁对含芳环有机分子选择性作用的特点，以瓜环和杯芳烃为构筑模块，设计、合成特定结构的瓜环和杯芳烃；选择结构、性质匹配的瓜环-杯芳烃组合，通过瓜环的外壁作用构筑结构新颖、性质特异的超分子自组装体，探究构筑机制，达到能动设计、调节和控制合成，是本项目的核心内容，也是本项目的研究目标和拟解决的关键科学问题。包括：普通瓜环-杯芳烃超分子自组装体的构筑及表征；取代基在特定位置上的瓜环与杯芳烃的超分子自组装体的构筑及表征；非水溶剂中半瓜环与杯芳烃的超分子自组装体的构筑及表征。在此基础上，研究瓜环-杯芳烃超分子自组装体功能性质，包括：瓜环-杯芳烃超分子自组装体基本性质；吸附；分离；富集等功能性质。发展和促进形成瓜环化学或杯芳烃化学中的一个新的研究方向。

It is well known that the Q[n]-based host-guest chemistry and coordination chemistry are two main research areas in the Q[n]-chemistry, whereas the functions of the electropositive outer surface of Q[n] is rarely known. In this project, based on factor of the selctive interaction of outer surface of Q[n] for the aromatic ring, we will select, design and synthesise cucurbit[n]urils and calix[m]arences with proper structure features as building blocks, construct of a series of supramolecular self-assmblies of cucurbit[n]uril-calix[m]arence hybrids based on the outer-surface interaction of Q[n] and investigate the formation machanism, which are our main aim and key scientific point. The main content in the project includes: the construction and characteristics of supramolecular self-assmblies of normal cucurbit[n]urils and calix[m]arences systems; alkyl-substituted cucurbit[n]urils and calix[m]arences systems; hemicucurbit[n]urils and calix[m]arences. Based on the invastigations of the cucurbit[n]uril-calix[m]arence-based supramolecular self-assmblies, the functional properties, including basic properties of themsevles, absorption for gases or volatile compounds, seperation as a fix phase materials, and enrichment of certain materials. At last, a new research area could be established in the cucurbit[n]url chemistry or calix[m]arence chemistry.
