摘要

芳香型席夫碱键因其共轭结构和动态可逆性，在动态共价化学领域占据重要地位。与脂肪型席夫碱不同，芳香或杂芳香骨架的引入不仅使席夫碱键具有更优异的热/机械稳定性，也可以通过电子离域效应调节其动态交换能垒和刺激响应行为。本文总结了2种典型结构(芳基-烷基取代和全芳基取代)对芳香型席夫碱键稳定性及动态行为的影响规律；阐述了芳香型席夫碱键的水解/缩合平衡和交换反应机理，以及取代基电子效应和酸催化对动态交换路径的控制规律；梳理了基于芳香席夫碱键的聚合物材料在光/热诱导自修复、再加工与回收、阻燃性、抗菌和催化等领域的应用进展。通过总结芳香型席夫碱键的结构调控动态行为及其聚合物材料多功能应用，为进一步发展高稳定性和智能响应性的多功能芳香席夫碱聚合物提供参考。

Abstract

Aromatic Schiff base bonds

due to conjugated structure and reversible dynamic characteristics

play an important role in dynamic covalent chemistry. Unlike aliphatic Schiff base bonds

the introduction of aromatic or heteroaromatic skeletons not only endows Schiff base bonds with improved thermal and mechanical stability

but also allows the dynamic exchange barrier and stimulus-responsive behaviors to be tuned by electronic delocalization. This paper summarizes the effects of two representative structural motifs (e.g.

aryl-alkyl and fully aryl substitution) on the stability and dynamic behavior of aromatic Schiff base bonds. Subsequently

it discusses the hydrolysis/condensation equilibrium and exchange mechanisms

and reveals the role of substituent electronic effects and acid catalysis in controlling dynamic exchange pathways. Recent progress in polymeric materials based on aromatic Schiff base are reviewed

focusing on applications in light-/heat-triggered self-healing

reprocessing and recycling

flame retardancy

antibacterial materials

and catalysis. This work provides a useful reference for the design and development of highly stable

smart

and multifunctional aromatic Schiff base polymers.
