Energy- and electron-transfer processes in porphyrin dendrimers

A recent development of dendritic macromolecules has provided a new methodology for the design of well-controllable threedimensional nano-object. Dendrimers generally consist of three different 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 architecture with porphyrin derivatives.
