where the TTF moieties are repeating every 22.701(5) Å. TTF-tetrabenzoic acid was already reported to yield hydrogen-bonded frameworks with conductivities in the 10 -7 -10 -6 S/cm range. The , orange dashed bonds for - stacking). In the packed structure, 1D channels are defined between the cages with a size of 4 x 9 Å (Figure ). These are filled with disordered electronic density which was removed using the Solvent Mask function of the Olex2 suite. The weak inter-cage interactions and the 39% solvent occupied volume explain the lack of stability of the cages upon desolvation. In conclusion, the synthesis and characterization of a new highly flexible ligand bearing an electroactive tetrathioalkyl-TTF core was performed. Its redox activity was assessed by cyclic voltammetry and is similar to the parent molecule TMT-TTF. Despite its high degree of freedom, a cage was self-assembled from L with Cu(II) paddlewheel linkers from two different solvent systems. The structures displayed solvent accessible volumes both inside and outside the cages in the solid state. Thanks to the four redox-active moieties per cage, up to 8 e -per cage could in theory be exchanged, and one can expect large size variations upon expansion of the cage in solution through the breaking of the internal Hbonding system. Solid-state cyclic voltammetry proved that the MOPs retained partially a reversible redox activity in the bulk. Further works are ongoing to solubilize the cages by using other metal centers such as Cr(II), Mn(II) or Rh(II) and using functionalized imidazolates to occupy the external apical paddlewheel positions and increase the cage solubility in common organic solvents.
