摘要

In the development of highly efficient materials for harvesting solar energy, there is an increasing focuson purpose-built dendrimers and allied multi-chromophore systems. A proliferation of antennachromophores is not the only factor determining the sought light-harvesting efficiency; the internalgeometry and photophysics of these molecules are also crucially important. In particular, themechanisms by means of which radiant energy is ultimately trapped depends on an intricate interplay ofelectronic, structural, energetic and symmetry properties. To better understand these processes a soundtheoretical representation of the intramolecular electrodynamics is required. A suitable formalism,based on quantum electrodynamics, readily delivers physical insights into the necessary excitationchannelling processes, and it affords a rigorous basis for modelling the intramolecular flow of energy.
