Abstract

During the last five years we devoted our research toward broadening the applications of planar extended p-conjugated NHC ligands for the preparation of organometallic-based supramolecular structures,^[1] including their use as hosts for some selected organic and inorganic guests, together with the catalytic properties displayed by some selected host-guest inclusion complexes. Our contribution describes the design of several Ni-,^[2] Pd-^[3] and Au-based^[4] metallorectangles, and metalloprisms, which we used for the encapsulation of several organic substrates, such as polycyclic aromatic hydrocarbons (PAHs) and fullerenes. We also described a series of di-gold(I)-based metallotweezers,^[5] and even a new mechanically interlocked molecule (MIM) that we named clippane.^[6] Depending on their structural features, these species were used for the recognition of a variety of organic substrates, such as electron-deficient aromatic substrates, polycyclic aromatic hydrocarbons and heavy metal cations.

In addition to all this, we recently focused our attention on the design of redox-switchable catalysts based on the use of a naphthalene-di-imide core. ^[7] We will show how these redox switchable catalysts can be used for unveiling key information about the mechanism of certain catalytic reactions.
