Scientific Mapping about Detoxification of Chemical Warfare Agents using Porous-Organic-Polymers with Internal Molecular Free Volume

Abstract

Chemical warfare agents (CWA’s) have consistently been a global concern regarding both defence and civilian safety. In order to safeguard people from these harmful chemicals, numerous research teams have collaborated with defence organizations for an advanced technological solution regarding effectiveness and strength. In this context, porous organic polymers (POPs) have been thoroughly investigated as an ideal option for catalytically detoxifying CWA’s by initially capturing them and subsequently transforming them into harmless chemicals. POPs are a new category of porous organic materials primarily made up of organic components linked by robust covalent bonds, resulting in highly interconnected frameworks with firm structures and defined voids for housing guest molecule. This feature article offers a summary of current studies concerning different synthetic methods for POPs (HCPs, PIMs, and certain amorphous POPs), potential modifications to their functionality, and their promising use in photocatalytic/thermal detoxification of chemical warfare agents (CWA’s). This review underscores the need for ongoing research to create effective, safe, and ecofriendly decontamination techniques. Ultimately, various catalytic process of detoxification like hydrolysis, oxidation was explored with POPs and mechanism was established through structure activity relationship with various novel techniques. Additional needs and potential applications of utilizing POPs as nanoreactors for the detoxification of CWA’s have also been discussed.
