Abstract:
A 3D porous perchlorinated metal–organic framework (MOF), LIFM‐26, featuring dual functionality, that is, functional polar groups and open metal sites, has been synthesized using perchlorinated linear dicarboxylate to link trigonal prismatic Fe 3 (μ 3 ‐O) units. LIFM‐26 exhibits good thermal and chemical stability, and possesses high porosity with a BET surface area of 1513 m 2 g −1 , compared with isoreticular MOF‐235 and Fe 3 O(F 4 BDC) 3 (H 2 O) 3 (F 4 BDC=2,3,5,6‐tetrafluorobenzene‐1,4‐dicarboxylate). Most strikingly, LIFM‐26 features good gas sorption/separation performance at 298 K and 1 atm with IAST selectivity values reaching up to 36, 93, 23, 11, 46, and 202 for CO 2 /CH 4 , CO 2 /N 2 , C 2 H 4 /CH 4 , C 2 H 6 /CH 4 , C 3 H 8 /CH 4 , and R22/N 2 (R22=CHClF 2 ), respectively, showing potential for use in biogas/natural gas purification and CO 2 /R22 capture.
