Abstract
Photoinduced energy transfer in large molecular systems is a vital process in many biological systems. The primary step in these reactions, such as photosynthesis, is a multi-step process of energy flow from a highly absorbing antenna molecule or moiety to a reaction center.1–5 In general, however, this process is energetically disordered, and thus the energy transfer is dependent upon mechanisms such as random walk, thermal activation, exciton percolation, or a combination of these effects.6–8 In contrast, a large, well ordered molecule with organized local electronic excitation states may provide an efficient means of directed intramolecular energy transport. In this paper we examine a unique class of recently synthesized dendrimeric molecules which exhibit such desirable properties.9,10 These represent the largest purely hydrocarbon dendrimers which have been synthesized to date.
