摘要

结晶聚合物材料的性质和应用在很大程度上取决于它们的结晶度. 快速制备高结晶度或单晶聚合物材料不仅有利于研究其结构-性能关系，同时可以拓展其实际应用领域. 然而，通过聚合将有机小分子高效精确地组装成单晶聚合物是一项具有挑战性的任务. 为了解决这个问题，我们课题组开发了一种超临界溶剂热法来实现聚合物单晶的超快制备. 该方法使用超临界二氧化碳作为反应介质，由于其具有高扩散率和低黏度，所以该方法极大地提高了聚合物晶体的生长速率. 本专论回顾了共价有机框架材料的发展及常用合成方法，以及在单晶制备方面面临的挑战. 从超临界流体的基本性质和应用、超临界溶剂热法的机理和优势、制得的共价有机框架单晶的结构表征和性质测试等方面系统介绍了基于超临界溶剂热法的聚合物单晶超快制备. 最后，对超临界溶剂热法合成聚合物单晶面临的挑战和发展方向进行了展望.

Abstract

The properties and applications of crystalline polymer materials largely depend on their crystallinity. Rapid preparation of high crystalline or single crystal polymer materials is not only beneficial for studying their structure-property relationship

but can also expand their practical applications. However

efficiently and accurately assembling organic molecules into polymer single crystals through polymerization is a challenging task. To address this issue

our group has developed a supercritically-solvothermal method for achieving ultra-fast preparation of polymer single crystals. This method uses supercritical carbon dioxide as the reaction medium

which greatly improves the growth rate of polymer crystals due to its high diffusion rate and low viscosity. This feature article reviews the commonly used synthesis methods for covalent organic frameworks (COFs)

as well as the challenges faced in single crystal preparation. Then

the basic properties and applications of supercritical fluids

the advantages of supercritically-solvothermal method

and the structural characterization of the prepared COF single crystals are systematically discussed. Finally

the challenges and development directions faced in the synthesis of polymer single crystals by supercritically-solvothermal method are prospected.
