Design and synthesis of triazine-based porous organic polymers towards green future

Abstract

In recent times functional porous materials have drawn significant interest because of their wide range of applicability. The latest among all is the porous organic polymer (POP). POP is an umbrella term that can be classified as the covalent organic framework (COF) and covalent organic polymer (COP) [1]. Since its inception in 2005 by Yaghi and co-workers [2], people have designed innumerable POPs by using various building blocks [3]. Common organic reactions such as imine condensation reaction, C−C coupling reactions, Knoevenagel condensation, etc. are used to synthesize POPs [4,5]. The covalently bonded network structure provides significant structural and thermal robustness, which is beneficial for use in acidic as well as alkaline mediums in fuel cells and batteries. Apart from the stability of the POPs, large surface area, well-defined pore structures, tunable porosity, and functionality, allow us to use them to tackle challenges that arise in the fields of environment, energy, biomedical, etc.
