This review provides an overview of the synthesis of layer-by-layer (LbL) assemblies containing calix[]arene (CA[]) and cucurbit[]uril (CB[]) and their applications. LbL assemblies, such as thin films and microcapsules, containing selective binding sites have attracted considerable attention because of their potential use in separation and purification, sensors for ions and molecules, and controlled release. CA[]-containing LbL films have been prepared using sulfonated CA[] and cationic polymers to construct chemical sensors and molecular containers. CA[]-containing LbL films deposited on the surface of a porous support are useful as ion-selective membranes that exhibit selective permeability to monovalent ions over multivalent ions. CB[]s have been used as molecular glues for the construction of LbL films and microcapsules by taking advantage of the strong affinity of CB[]s to aromatic compounds. CB[]s form a stable 1:1:1 ternary complex with electron-rich and electron-deficient molecules in LbL films to stabilize the assemblies. CB[]-containing LbL films can also be deposited on the surfaces of micro templates and nanopore membranes to construct microcapsules for controlled release and nanochannels for selective ion transport, respectively.
本文综述了含杯芳烃（CA[]）和葫芦脲（CB[]）的层层（LbL）组装体的合成及其应用。含有选择性结合位点的LbL组装体，如薄膜和微胶囊，因其在分离和纯化、离子和分子传感器以及控释方面的潜在应用而备受关注。含CA[]的LbL薄膜已通过磺化CA[]和阳离子聚合物制备而成，用于构建化学传感器和分子容器。沉积在多孔载体表面的含CA[]的LbL薄膜可用作离子选择性膜，对单价离子表现出比对多价离子更高的选择性渗透性。CB[]已被用作分子胶水，通过利用CB[]与芳香族化合物的强亲和力来构建LbL薄膜和微胶囊。CB[]在LbL薄膜中与富电子和缺电子分子形成稳定的1:1:1三元复合物，以稳定组装体。含CB[]的LbL薄膜也可分别沉积在微模板和纳米孔膜的表面，以构建用于控释的微胶囊和用于选择性离子传输的纳米通道。
