Covalent Organic Frameworks: An Amazing Chemistry Platform for Designing Polymers

Summary Covalent organic frameworks emerged as a class of polymers that enable the construction of ordered skeletons and pores via simple polymerization, offering a unique chemistry platform that greatly enhances our capability of designing organic structures and functions. In this perspective, we analyze the structural design and synthesis by highlighting distinct features and bottleneck problems. We scrutinize major functions by correlating structure-function relationships and disclosing the key structural parameters and interfaces that control various interplays to show the key achievements and our conceptual insights. We foresee the fundamental issues, core directions, and challenges in the viewpoints of chemistry, physics, and materials science with the aim of exploring ordered organic materials with unique structures and functions.
