超分子自组装是指相同或不同分子间通过非共价键弱相互作用自发构成具有特定结构和功能的分子聚集体的过程。阴离子作为构筑基元能够诱导出独特的组装结构，然而，阴离子由于其自身的化学性质和结构特点使得结合能力相对较弱，缺乏方向性，这大大增加了构建阴离子主导的自组装超分子体系的难度。本项目致力于设计合成基于咔唑类的具有不同空腔大小、不同官能团化超分子大环主体。同时，申请人将研究这些大环主体对具有不同体积大小、不同空间结构的阴离子络合能力，并进一步研究阴离子络合对大环主体自组装行为的影响。此外，申请人拟以阴离子为配位中心,构建阴离子驱动的阴离子配位聚合物。这些研究的开展将有助于构建阴离子主导的自组装超分子体系，丰富与发展具有特定功能的阴离子配位聚合物的研究，促进超分子化学新研究方向和新学术增长点的开拓。

Supramolecular self-assembly is the process that different building blocks form well-defind structures with specific functions driven by various weak interactions. Anion as building blocks can induce unique assembly structures. However, due to anion's relatively weak binding ability, it's hard to construct anion dominant supramolecular self-assembly system. The aim of this project is to study on design and syntheses carbazole-based macrocycles with different cavity size and different functional groups. We will study the anion binding behavior and the effect of anionic complexation on the self-assembly behavior of the macrocyclic hosts. Besides, we will build anion-driven supramolecular polymers. These will help build anion-dominated self-assembled supramolecular systems, enrich the research of anion-driven supramolecular polymers with specific functions, leading to the development of new research directions and new academic growth points for supramolecular chemistry.
