Photoinduced Electron Transfer through Dendrimer Architecture

4 PHOTOINDUCED ELECTRON TRANSFER THROUGH DENDRIMER ARCHITECTURE 

Long-range electron transfer reactions have attracted attention relative to the initial stages of photosynthesis, and special interest has been focused on the design of noncovalently assembled donor-acceptor arrays. Dendrimers with spatially isolated porphyrin cores are potential motifs for investigating such long-range electron transfer reactions [12],

Poly(benzyl ether) dendrimers have several unique optical and photochemical properties. In particular, it is quite interesting that some photochemical events are considerably affected by the molecular size and morphology of the dendrimer molecules. These examples, together with those by other researchers [2], will provide a new strategy toward next-generation, nanoscopic photofunctional materials. 

Azodendrimers with a different substitution pattern at the core unit have been reported in Junge, D. M. and McGrath, D. Y. Chem. Commun., 857 (1997).
