Porous Organic Polymers

POPs: Porous organic materials have attracted significant attention in the last few years due to their high surface area and functionalizable pores. Considering the facts of (i) the superior chemical, thermal and hydrothermal stabilities arising from strong covalent bonds, (ii) structural and functional tunability, (iii) lightweight because of B, C, N, O, H-based building blocks, porous organic polymers (POPs) have emerged as an important theme in the current research. The tunable pore size with the high surface area as well as excellent structural robustness trigger their extensive utilization from the gas storage and separation to heterogeneous catalysis and water purification. Amidst all the advantages, the judicious inclusion of -electron conjugation in the network makes the conjugated porous organic polymer (CPOPs) unique from all other porous materials. Hence, CPOPs became popular for their multimodal applications like sensing, light harvesting, photocatalysis and energy storage. In this present scenario of the field, our group took up the problem to meet various challenges like designing the task-specific building blocks, tuning the band gap and porosity and most importantly development of POPs with solution processability. Along with the design strategy, we have also demonstrated the efficacy of POPs in diverse applications ranging from chemo/ biosensing, light harvesting, energy storage, photocatalysis, to metal-free CO2 fixation.
