A [(M2)6L8] metal–organic polyhedron with high CO2 uptake and efficient chemical conversion of CO2 under ambient conditions

Abstract

A new metal–organic polyhedron with a high surface area of 407 m² g⁻¹, possessing high CO₂ uptake, is reported, which is synthesized using 4-connected Cu₂(CO₂)₄ paddle-wheel moieties and 3-connected semi-rigid tripodal carboxylates. This material possesses a high density of Cu(II) Lewis acidic sites and demonstrates excellent performance as a heterogeneous catalyst for the chemical fixation of CO₂ into cyclic carbonates under ambient conditions.
