Helicates luminescent bioprobes

Elhabiri et al., 2004a). The ultimate fixation of the third ligand in the neutral helicate [f 2(L13%] induces a considerable entropic gain to the overall complexation process, which is responsible for both extreme thermodynamic stability (Elhabiri et al., 1999) and kinetic inertness (Elhabiri et al., 2004b, Figure 59), which make these helicates promising building blocks for the development of luminescent bioprobes (see Section 6).
