Conjugated Porous Polymers and Hybrids

Abstract

Conjugated porous polymers (CPPs) are a rapidly developing domain of extended organic networks featuring permanent nanoporosity and a robust chemical backbone, resulting in impressive thermal and chemical stability. For this reason, these porous polymers have been used extensively in gas and harmful organic adsorption and heterogeneous catalysis. As the CPPs offer manual control over the choice of monomers and their relative occupancy in the final polymer structure, these networks can be made as extended conjugated organic systems or as heterogenized molecular catalysts with tuneable properties. These CPPs have also been hybridized with metal nanoparticles, complexes, and carbon networks, e.g., carbon nanotube and graphene, to instigate add-on catalytic, adsorption, and electronic conduction properties. The standalone CPPs, and their composites, are being extensively studied in the literature in these applicative domains. Efforts are being made to draw a structure–property relationship between the chemical structure, morphology and adsorption or catalytic properties of these materials. In this chapter, we have systematically combined these aspects to provide a general overview of the topic.
