The field of supramolecular chemistry has been recently extended to the construction of structures involving a molecular movement in the process of supramolecular recognition. Special attention is addressed in the design of dynamic architectures in which the complexation is controlled by an external stimulus. These systems present great potential for application in molecular electronics for the development of molecular machines. In this context, the recognition of neutral molecules is a difficult goal to achieve because of the small range of host-guest interactions. To meet this challenge, we have recently synthesized original structures such as molecular clips built around more or less flexible platforms with electron enriched sidewalls using the donor tetrathiafulvalene (TTF). We present in this manuscript the different strategies considered for the synthesis of these clips bearing electroactive units and the results obtained for the recognition of electrodeficient planar (TCNQ-F4) or threedimensional (fullerene C60) guests thanks to increased donor-acceptor interactions.
