Scheme 1

Synthesis of the [2]pseudorotaxanate [1•Cu]·PF6 and MOF-1040. The synthesis of the [2]pseudorotaxanate was achieved using metal-templated protocols—the copper-complexed ring 3 was added to a solution of 2 in CH2Cl2 to form the [2]pseudorotaxanate [1•Cu]·PF6. Red cubic crystals, suitable for X-ray crystallographic analysis, were obtained by mixing [1•Cu]·PF6 and Zn(NO3)2.6H2O in N,N-diethylformamide in a sealed tube at 100 °C for 2 days.
