In this work we have explored, by static and dynamic gas sorption techniques and computational modelling, the suitability of a series of two isoreticular robust Ni(II)pyrazolate-based MOFs, bearing alkyne moieties on the ligand backbones, for C2H2/CO2 separation. The results are consistent with high adsorption capacity and selectivity of the essayed systems towards C2H2 molecules. Furthermore, a post-synthetic treatment with KOH ethanolic solution gives rise to linker vacancy defects and incorporation of extraframework potassium ions. Creation of defects is responsible for increased adsorption capacity for both gases, however, strong interactions of the cluster basic sites and extraframework potassium cations with CO2 molecules are responsible for a lowering of C2H2 over CO2 selectivity.}, organization = {EU Feder funding, MINECO (CTQ2017-84692-R)}, organization = {Junta de Andalucia (P18-RT-612)}, organization = {Italian Ministry of University and Research is acknowledged for financial support through the PRIN 2107 Program (Project 2017KKP5ZR)}, organization = {Tarbiat Modares University for funding support}, publisher = {Wiley-Blackwell Verlag GmbH}, keywords = {Breakthrough curves}, keywords = {Carbon capture}, keywords = {Gas separation}, title = {Impact of Pore Size and Defects on the Selective Adsorption of Acetylene in Alkyne-Functionalized Nickel(II)- Pyrazolate-Based MOFs}, doi = {10.1002/chem.202100821}, author = {Afshariazar, Farzaneh and Morsali, Ali and Sorbara, Simona and Muñoz Padial, Natalia and Roldán Molina, Esther and Oltra Ferrero, Juan Enrique and Colombo, Valentina and Rodríguez Navarro, Jorge Andrés}, }
