共价有机骨架是一种交联结晶聚合物,由刚性有机前体通过共价相互作用连接构成。共价有机骨架具有非常理想的属性组合,包括灵活的化学可调性、结构多样性和极佳的稳定性,因此已经成为了极具发展潜力的纳米多孔材料。然而,尽管三维共价有机骨架具有显著的优势,但是研究工作仍然集中在更易合成的二维变体上。

在《通讯-化学》发表的Approaches and challenges in the synthesis of three-dimensional covalent-organic frameworks一文中,来自美国密歇根大学的Timothy F. Scott及其团队概述了三维共价有机骨架的合成方法,明确了阻碍该领域发展的合成方面的障碍,以及最近所采用的解决办法,并进一步提出了一些能规避这些合成难题的替代性技术。

摘要:Covalent organic frameworks, cross-linked crystalline polymers constructed from rigid organic precursors connected by covalent interactions, have emerged as a promising class of nanoporous materials owing to their highly desirable combination of attributes, including facile chemical tunability, structural diversity, and excellent stability.Despite the distinct advantages offered by three-dimensional covalent organic frameworks, research efforts have predominantly focused on the more synthetically-accessible, two-dimensional variants. Here we present an overview of synthetic approaches to yield three-dimensional covalent organic frameworks, identify synthetic obstacles that have hindered progress in the field and recently-employed methods to address them, and propose alternative techniques to circumvent these synthetic challenges.
