C2H2, C2H4 and C2H6 adsorption isotherms of a NTU-96, b NTU-97 and c NTU-98 at 298 K, respectively. Comparison of d C2H4/C2H2 and e C2H6/C2H2 uptake difference of the benchmark PCPs at 298 K, 50 kPa. Values for literature materials are taken from refs: Al-PyDC43, Uio-67-(NH2)231, TJT-10029, [Zn(BDC)(H2BPZ)].4H2O44, NTU-73-CH345, HIAM-21046, Cu-FINA-247, BSF-148, MOF-52549, NPU-230, Azole-Th-125 and NUM-750. f IAST selectivity of C2H6/C2H2 (1/1, v/v) and C2H4/C2H2 (1/1, v/v) at 298 K.
