An alternative approach to the realization of self-assembled
chemosensors, called ‘‘chemosensing ensemble’’, has been pro-
posed and involves the displacement of a non-covalent dye–
receptor complex by the substrate. See for example: (a)

Acc. Chem. Res., 2001, 34, 963–972; (b) M. A. Hortal a` ,

9 In the hypothesis of a homogeneous distribution of the subunits,
the quenching of 20% of the dyes implies that 20% of the particle
surface area is the quenching ‘‘dominion’’ of the Cu(II) ions. A
single particle (radius 9 nm) contains about 7000 subunits and
hence 140 ligand units.
