The preparation of copper( ii ) one-dimensional MOFs using an eco-efficient method is reported here. This method is based exclusively on using supercritical CO 2 as a solvent, without the addition of any other additive or co-solvent. Neutral acetylacetonate copper complexes and two linear linkers, namely, the bidentate 4,4′-bipyridine and 4,4′-trimethylenedipyridine molecules, were reacted under compressed CO 2 at 60 °C and 20 MPa for periods of 4 or 24 h. The success achieved in the synthesis of the different studied 1D-MOFs was related to the solubility of the reagents in supercritical CO 2 . The reaction yield of the synthesized coordination polymers via the supercritical route was close to 100% because both the reactants were almost completely depleted in the performed experiments. The preparation of copper( ii ) one-dimensional MOFs using scCO 2 as solvent is reported.
