Light harvesting unsymmetrical conjugated dendrimers as photosynthetic mimics.

Zhonghua Peng1, Joseph S Melinger, Valeria Kleiman.   

Abstract

We review the synthesis and photophysical properties of light harvesting phenylacetylene dendrimers with unsymmetrical branching. We describe the steady state and time dependent experiments that are used to characterize energy transfer properties in the conjugated dendrimers. Finally, we describe investigations of the unsymmetrical phenylacetylene dendrimers as potential materials for applications in fluorescence-based sensors, and for non-linear optics.
