Site binding model extended

For simple processes in which multiple metals bind to a single ligand = 1 and iEL = 1 (AEE1 = 0) and hence the extended site binding model reduces back the basic site binding model. Figure 10.17 shows... 

Table 10.2 Equilibria, binding constants, extended site binding model parameters and cooperativity for the formation of the Eu(III) complex of 10.9 (L).

The thermodynamics of self-assembled systems are often characterized by positive co-operativity at the molecular level, however the thermodynamic analysis of co-operativity in self-assembly is complexes such as helicates is complicated by the occurrence of both inter- and intramolecular steps. It may be understood using the extended site binding model. 

Mixing intra- and intermolecular connections The extended site-binding model... 

Let us first apply the extended site-binding model (Eq. (100)) to the four complexation processes shown in Eigure 90 (Eqs. (118)-(121)). 

The introduction of fhese values into Eq. (126) shows that the solvation correction and the Coulombic repulsion are of the same magnitude, but of opposife trend, which explains the minute apparent intermetallic interaction detected in solution when using the extended site-binding model (Eq. (128)). 

The group of Piguet has extensively apphed the extended site binding model to rationalize the self-assembly behaviour of a large number of polymetallic complexes, especially of the f-block. The many interesting results obtained by Piguet and coworkers are outside the scope of the...
