Recent advancement in viologen functionalized porous organic polymers (vPOPs) for energy and environmental remediation

Abstract

A rise in the concentration of hazardous and noxious substances in the environment due to industrialization and population expansion has begun to disrupt the ecological equilibrium. It is of utmost importance to monitor and efficiently manage these pollutants through adsorption techniques or catalytic degradation. Viologen-based porous organic polymers (vPOPs) are a class of porous polymeric materials composed of 4.4′-bipyridinium ions along with other small organic molecules linked together by strong covalent bonds. They have garnered attention as a viable platform for many applications, particularly in the realm of effective environmental remediation. This advancement has generated prospects for the development of more advanced techniques for eliminating contaminants, segregating chemicals, converting gases, and transforming energy. The purpose of this study is to provide an overview of the most recent advancements and successes in the production, utilization, and structural engineering of vPOPs and associated composite materials to remediate environmental problems. This detailed study seeks to provide insights into the potential of vPOPs as viable materials for addressing environmental challenges and stimulating additional research in this emerging sector. This paper provides an analysis of the perspectives about the challenges, opportunities, practical applications, and prospects of these materials in advanced remediation technology for the next generation.
