摘　　要：Comprehensive Summary Due to the extremely similar physical and chemical properties of C_(2)H_(6),C_(2)H_(4),and C_(2)H_(2),purifying ethylene from the C_(2)ternary mixture in one-step is very challenging.In this work,we developed a series of pillar-layered MOF materials((Ni(BTC)(Bipy),Ni(BTC)(3-Me-Bipy),and Ni(BTC)(3-NH_(2)-Bipy))through the functionalization of pillar ligands using pore engineering strategies.Single-component adsorption isotherm measurements demonstrate that these materials preferentially adsorb C_(2)H_(6)and C_(2)H_(2),thereby achieving one-step purification of the three C_(2)hydrocarbons to obtain C_(2)H_(4).
