Abstract: Porous materials attracted [1] a significant deal of attention in recent years due to their permanent porosity, chemical tunability, physicochemical stability, and exceptional gas sorption properties. Our main approach in this field is the so-called “bottom-up” approach where the concept of molecular recognition is being used along with covalent synthesis to arrange molecules to form multifunctional integrated systems for addressing energy and environmental challenges. We also actively explore sustainable polymerization strategies for the synthesis of porous materials. In this direction; we have developed [2-3] porous organic polymers incorporating molecular cages/macrocycles as monomeric units and showed that their intrinsic properties such as their ability to bind guest molecules in solution can be transferred into the solid state for the affinity-based separation of gas mixtures. In an effort to synthesize two-,[4] three-dimensional porous semiconductors,[5] we introduced Diels-Alder cycloaddition polymerization reaction and the resulting polymers studied for their conductivity as well as for atmospheric water uptake prior to aromatization. We also developed a sulfur-rich porous material towards natural gas sweetening[6], Li-sulfur batteries[7,8] as well as Pd capture from waste conditions. More recently, we have also developed hybrid two-dimensional membranes for H2/He and H2/CO2 separation applications.
