A large guest for a small host : The tweezering process about the bipyridinium core of a dendrimer by a molecular tweezer (see picture) has been studied electrochemically and by fluorescence spectroscopy and is found to be quite similar to the threading/dethreading processes observed with wire‐type bipyridinium‐based units and ring‐shaped molecules.
