摘要

响应性高分子是智能高分子的重要组成部分，其可以感应外部刺激、通过改变高分子结构实现对高分子功能的精确调控. 气体作为一种不同于常规物理或化学信号的“绿色”刺激方式，用于对高分子自组装过程的调控具有重要意义. 然而，由于气体分子通常缺乏可控反应位点且调控过程难以量化控制，目前这一刺激-调控方式的发展相对缓慢. 面对上述挑战，本文系统介绍了“气敏高分子”与“气筑高分子”两类新型气体调控的高分子组装系统. 结合本课题组工作，总结了以生命体三大气体信号分子——硫化氢(H

S)、一氧化碳(CO)和一氧化氮(NO)为刺激源，面向气敏高分子的设计与可控组装方面的研究进展；以及通过气体动态化学，以二氧化碳(CO

)等气体为连接单元，面向气筑高分子的结构设计、动态自组装及其功能应用方面的研究工作.

Abstract

Polymer self-assembly is an important branch of the self-assembly field

and research on the precise control of its assembly process and function is necessary t

o further broaden its application scope. Gas

as a "green" stimulus

different from conventional physical or chemical signals

is of great significance for the regulation of the self-assembly process of polymers. Combining the work of our research group

this paper systematically introduces two types of new gas-regulated polymer assembly systems: "gas-responsive polymers" and "gas-constructed polymers". Gas-responsive polymers can respond to external gas signal stimulation

change their amphiphilicity or aggregation state by reacting with gas molecules and specific chemical moieties in the polymer

thereby affecting their self-assembly behavior and outputting functions. The progress of research on the design and controllable assembly of gas-sensitive polymers is summarized

focusing on the three major gas signal molecules in living organisms—hydrogen sulfide (H

carbon monoxide (CO)

and nitric oxide (NO) as stimuli sources. Gas-constructed polymers use gas molecules as assembly units to construct polymer materials. Then introduces the "dynamic gas bridge" formed between boron/phosphorus frustrated Lewis acid-base pairs and gas molecules such as carbon dioxide (CO

)

as well as research on the structure design

dynamic self-assembly

and functional applications of gas-constructed polymers. Finally

the future development of these two types of gas regulated polymers was discussed. Gas-responsive polymers can be used in the design of multi-signal molecule-programmed responsive systems

achieving intelligent intracellular targeted release and carrier transport functions. Gas-constructed polymers

while having universality for a broad spectrum of gas molecules

lack selectivity for single gas molecules and have poor chemical tolerance in the design of complex functions. The solution to this problem will lay the foundation for the development of a wider range of functional gas-constructed assembly materials.
