ABSTRACT
A recent development of dendritic macromolecules has provided
a new methodology for the design of well-controllable three-
dimensional nano-object. Dendrimers generally consist of three dif-
ferent topological parts, i.e., focal core, monomeric building blocks,
numbers of terminal functional groups. For the design of novel
photofunctional nano-devices, many efforts have been paid for the
incorporation of porphyrin derivatives into each topological parts
of dendrimer structure. In this chapter, we are going to discuss
about energy and electron transfer processes in dendritic architec-
ture with porphyrin derivatives.
