Summary on Grant Application Form |
The Forster theory of resonance energy transfer was first devised to explain the migration of electronic energy from photo-excited donor molecules to acceptors beyond wavefunction overlap. Operative in a wide range of materials and applications, this process plays a central role in light-harvesting materials. At the levels of intensity now routinely applied in ultrafast laser studies of organic and biological materials, the high levels of excitation permit the operation of multi-donor transfer, with some of the first experimental results on twin-donor systems recently reported. The aim of this proposal is to forge a general theory of multi-excitation energy pooling in systems comprising several donors - and to apply it to real systems, fully accommodating the characteristics of the host medium, and suitably addressing both symmetric and symmetry-disrupted systems. The first objective will be to develop fundamental theory for a three-donor system, interrogating the role of threefold symmetry in the donor array, and the effects of its local disruption. Research will then progress to real multi-tributary systems - fully allowing for the proper incorporation of refractive and dissipative effects. The theory is then to be applied to high intensity energy pooling in photoactive dendrimers and other photosynthetic mimics.
