An electroactive molecular clip incorporating tetrathiafulvalene (TTF) sidewalls grafted on a glycoluril platform has been synthesized using a straightforward DielsâAlder strategy. This way of attachment to the glycoluril U-shape scaffold afforded a rigidified and closed receptor for which the electron-rich TTF pincers are expected to be at a suitable distance for sandwiching neutral guests through donorâacceptor interactions. The efficient complexation ability of this host architecture toward one molecule of tetracyanoquinodimethane derivative (F4-TCNQ) in solution has been demonstrated using cyclic voltammetry and UV-Visible titration methods.
