Monomolecular layer polymeric nanocapsules can be easily prepared by the covalent self-assembly of the horizontal cross-linking of rigid building blocks and flexible cross-linker under certain conditions. Compared with the traditional noncovalent supramolecular vesicles, this new type of covalently self-assembled polymeric nanocapsules possess many advantages such as stable structure, controllable size, and excellent dispersibility. Therefore, it is of great significance to fabricate new covalent nanocapsules by means of chemical synthesis to realize their structural control and application exploration. Focusing on these problems, we have developed functionalized pillar[5]arene, tetraphenyl ethylene, porphyrin, triazine, phenylboronic anhydride, etc. to serve as basic building blocks, which were polymerized by flexible alkyl linkers to finally obtain the covalently cross-linked polymeric nanocapsules. Through the structural modification and regulation, we found the functionalized polymeric nanocapsules showed potential application in the field of light harvesting, artificial enzyme, antimicrobial and drug delivery. In the future, more application fields of the covalent polymeric nanocapsules are expected to be further explored.
