Tuning fluorocarbon adsorption in new isoreticular porous coordination frameworks for heat transformation applications.

ABSTRACT: Adsorption heat transformation is one of the most energy-efficient technologies, which relies much on the type and performance of the adsorbent-adsorbate pair. Here, we report adsorption behaviors of a typical fluorocarbon R22 (CHClF₂) in a new series of isoreticular porous coordination polymers [Zn₄O(bpz)₂(ldc)], in which the typical Zn₄O clusters are connected by hydrophobic 3,3',5,5'-tetramethyl-4,4'-bipyrazolate (bpz^2-) and different linear dicarboxylates (ldc^2-) to form non-interpenetrated pcu networks with variable pore sizes, shapes, and volumes. Fluorocarbon sorption measurements of these materials revealed high R22 uptakes of 0.73-0.97 g g^-1 (0.62-0.65 g cm^-3) at 298 K and 1 bar and work
