Abstract

A new microporous metal–organic framework, Cu₂(PDDI) (ZJU-5; H₄PDDI = 5,5′-(pyridine-2,5-diyl)diisophthalic acid), was solvothermally synthesized and structurally characterized. With open metal sites, Lewis basic pyridyl sites and suitable pore space, the acetylene uptake in ZJU-5a reaches the highest value of 290 cm³ g⁻¹ at 273 K and 1 bar. Furthermore, ZJU-5a exhibits high absolute methane storage of 190 cm³ (STP) cm⁻³ at 35 bar and 224 cm³ (STP) cm⁻³ at 60 bar at room temperature.
