Adsorption-based cooling is an energy-efficient renewable-energy technol. that can be driven using low-grade industrial waste heat and/or solar heat. Here, we report the first exploration of fluorocarbon adsorption using porous covalent organic polymers (COPs) for this cooling application. High fluorocarbon R134a equilibrium capacities and unique overall linear-shaped isotherms are revealed for the materials, namely COP-2 and COP-3. The key role of mesoporous defects on this unusual adsorption behavior was demonstrated by mol. simulations based on atomistic defect-containing models built for both porous COPs. Anal. of simulated R134a adsorption isotherms for various defect-containing atomistic models of the COPs shows a direct correlation between higher fluorocarbon adsorption capacities and increasing pore volumes induced by defects. Combined with their high porosities, excellent reversibility, fast kinetics, and large operating window, these defect-containing porous COPs are promising for adsorption-based cooling applications. In the part of experimental materials, we found many familiar compounds, such as Tris(4-bromophenyl)amine(cas: 4316-58-9COA of Formula: C18H12Br3N)
In general, Tris(4-bromophenyl)amine(cas: 4316-58-9) is often used in the synthesis of porous luminescent covalent–organic polymers (COPs)COA of Formula: C18H12Br3N
