Imine-linked covalent organic frameworks (COFs) have attracted considerable interest in recent years because they can form strong and reversible covalent bonds, enabling the development of highly ordered crystalline structures. This reversibility is crucial in correcting structural defects during the crystallization process, which requires sufficient time to proceed. This review critically examines the advancements in synthetic strategies for these valuable materials, focusing on catalytic versus conventional approaches. Traditional methods for synthesizing imine-linked COFs often involve harsh reaction conditions and prolonged reaction times, which can limit the scalability and environmental sustainability of these frameworks. In contrast, catalytic approaches offer more efficient pathways, enabling shorter reaction times, milder reaction conditions, and higher yields. This article elucidates the key differences between these methodologies and examines the impact of reduced reaction times and milder conditions on the crystallinity and porosity of COFs. By comparing the catalytic and conventional synthesis routes, this review aims to provide a comprehensive understanding of the advantages and limitations of each approach, offering insights into the optimal strategies for the development of high-performance COFs.
近年来，亚胺连接的共价有机框架（COFs）引起了广泛关注，因为它们能形成强且可逆的共价键，有助于构建高度有序的晶体结构。这种可逆性在结晶过程中校正结构缺陷方面至关重要，而这需要足够的时间来进行。本综述批判性地审视了这些有价值材料合成策略的进展，重点关注催化方法与传统方法。传统的合成亚胺连接COFs的方法通常涉及苛刻的反应条件和较长的反应时间，这可能会限制这些框架的可扩展性和环境可持续性。相比之下，催化方法提供了更高效的途径，能够实现更短的反应时间、更温和的反应条件以及更高的产率。本文阐明了这些方法之间的关键差异，并研究了缩短反应时间和采用更温和条件对COFs结晶度和孔隙率的影响。通过比较催化合成路线和传统合成路线，本综述旨在全面了解每种方法的优缺点，为开发高性能COFs的最佳策略提供见解。
