electron transfer showed potential application in the fabrication of new moleculebased devices.
Then, our group designed a novel kind of [2]pseudorotaxane assembly taking
advantage of host-guest binding between DB24C8 derivative, which decorated a
terpyridine unit as ligand for lanthanide ions, and fullerene-containing ammonium
salt (Fig. 12) [39]. Sensitized by terpyridine, the complex showed strong and unique
emission properties of Tb
3+ ion in the case of the unthread macrocycle. The
phenomenon of fluorescence quenching was observed after the addition of
Fig. 11 Schematic illustration of the fabrication of tris[2]pseudorotaxane assembly [38]. (Adapted
