动态共价化学的研究进展

Research Progress in Dynamic Covalent Chemistry

动态共价化学涉及的是一系列基于热力学平衡的可逆平衡的共价化学反应,其核心概念是可逆共价化学键,亚胺键、酰腙键、双硫键、酯键等都属于可逆共价化学键范畴。反应的可逆性质使动态共价化学的合成过程中有了校对和自修复的智能功能,通过引入特定结构、改变平衡条件来改变材料结构,通过温度、PH等的响应来实现超分子自组装控制其催化性能等应用。

Dynamic covalent chemistry involves a series of reversible equilibrium covalent chemical reactions based on thermodynamic equilibrium.The core concept is reversible covalent chemical bonds.Imine bonds,hydrazide bonds,disulfide bonds,ester bonds,etc.are all reversible covalent chemical bond’s category.The reversible nature of the reaction enables the intelligent function of proof-reading and self-repairing in the synthesis of dynamic covalent chemistry.The material structure is changed by introducing specific structures and changing equilibrium conditions,and through the response of temperature,PH,etc.,the application of supramolecular self-assembly to control its catalytic performance is realized.
