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

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 (CHClF(2)) in a new series of isoreticular porous coordination polymers [...

description 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 (CHClF(2)) in a new series of isoreticular porous coordination polymers [Zn(4)O(bpz)(2)(ldc)], in which the typical Zn(4)O 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 working capacities of 0.41–0.72 g g(–1) (0.35–0.47 g cm(–3)) between 273 and 313 K at about 0.13, 0.11 and 0.52 bar, respectively, as well as very large diffusion coefficients of 5.1–7.3 × 10(–7) cm(2) s(–1). Noteworthily, the R22 sorption performance can be dramatically improved by subtle modification of the pore size and shape, demonstrating porous coordination polymer–fluorocarbon as a promising adsorbent–adsorbate pair for heat transformation applications.
