摘要

三氟乙酸（TFA）是一种普遍存在的持久性环境污染物，对环境和人类健康具有重大影响。据我们所知，没有研究报告使用多孔有机聚合物来吸附TFA蒸汽。在这项研究中，我们成功地合成了一种聚合物（POPSP-4），它具有物理和化学吸附能力，可以有效地捕获TFA，并且物理吸附可以发生在硫位点。在有机碱的辅助下，聚合物的吸附量在1 h内由2.3 g·g - 1增加到4 g·g - 1以上，有效地阻止了TFA从聚合物中逸出。本研究为多孔有机材料的设计和合成提供了一种有前途的方法，特别是对于TFA蒸汽的有效捕获。

Spiro-Thioketal-Based Porous Organic Polycarbazoles for the Efficient Capture of Trifluoroacetic Acid Vapor

Trifluoroacetic acid (TFA) is a ubiquitous and persistent environmental pollutant with significant environmental and human health impacts. To the best of our knowledge, no study has reported the use of porous organic polymers to adsorb TFA vapor. In this study, we successfully synthesized a polymer (POPSP-4) that exhibits both physical and chemical adsorption for efficient TFA capture, and physical adsorption can occur at the sulfur sites. With the assistance of organic bases, the adsorption capacity of the polymer increases from 2.3 g·g^–1 to over 4 g·g^–1 in 1 h and effectively prevents the escape of TFA from the polymer. This study presents a promising methodology for the design and synthesis of porous organic materials, specifically for the efficient capture of TFA vapor.
