The book is divided into three sections. The first section provides a general overview of the fundamentals of supramolecular polymers. In Chapter 1, Thibault and Rotello provide a brief introduction to these systems and in Chapter 2, Azagarsamy, Krishnamoorthy, and Tha5mmanavan describe the rapidly emerging area of amphiphilicity in polymer and dendrimers self-assembly. Interactions at interfaces are sometimes similar but often quite different than those in solution, a topic covered by Loveless, Kersey, and Craig in Chapter 3.

Since the overall number of peripheral chains per dendritic molecule is changed, while the lattice parameter of the Colh phases remains roughly similar, the number of dendrimers self-assembling into columns is different in order to keep the total munber of radiating chains constant as shown in Fig. 55.

Several of these topological types (i.e., linear, cyclic, clusters) are remarkably reminiscent of those that are obtained by noncovalent self-assembly of proteins [8]. This offers a glimpse of the possible covalent topologies however, virtually no examples of dendrimer self-assembly by noncovalent, electrostatic type interactions have been reported until recently. Such abiotic, noncovalent PAMAM (G = 9) dendrimer self-assemblies have now been observed by atomic force microscopy (AFM) on freshly cleaved mica surfaces [268] (Figure 42). 

Another interesting application was given for diselenide-based block copolymers, where both oxidants as well as reductants forced the systems to a demicellization [275]. This system was further developed to allow the disassembly of the micelles by apphcation of oxidants, whereas micellization was favored in the presence of reductants [276]. In continuation, selenium-based peptides and dendrimers self-assembled into different morphologies, depending on the oxidation state [277, 278]. Also, small selenium-based amphiphiles form complexes with polyelectrolytes, but the amphiphihc character of the amphiphile and - in turn - the complex decreases after oxidation [279]. In general, the literature contains a... 

Very recently, a highly active fullerodendrimer catalyst able to mimic the superoxide dismutase enzyme has been reported [41]. On the other hand, Martin and his research group have recently reported a new supramolecular approach to C )-dendrimers, self-assembled by concave-[Pg.7]
