The Role of Chirality in Energy Transfer
Abstract
The exploration of chirality in energy transfer is an area of considerable significance and technological potential. Biological systems have evolved to demonstrate highly efficient information transfer, occurring through chirality-based structural recognition, as well as helical electron and light mediated pathways. However, the relationships between chirality and these transfer processes are still unclear, and how we can harness this understanding for technological applications is significantly underdeveloped. The proposed research presents an opportunity to discover new fundamental science, using chirality to bridge multiple fields of chemistry, materials science, and engineering. Our work has identified certain design rules that result in strong chiral optical and magneto-optical phenomena. We will build on these results and create a series of chiral functional materials (sulfur rich conjugated polymers and oligomers, molecules for thermally activate delayed fluorescence and liquid crystalline small molecules). The chirality dependent properties of these systems will be explored using a range of cutting-edge methods, with a focus on the measurement of energy transfer processes. Together with collaborative partnerships this work will identify a range of robust structure-property relationships that will be used to define the emerging physics of chiral systems. Our project has three aims- Aim 1- Understand the influence of chemical structure and molecular packing on light-matter interactions in chiral systems. Aim 2- Establish the influence of molecular chirality and helical electron transfer on spin polarisation (i.e. electron spin). Aim 3- Uncover the interactions between chiral molecules and polarised light in complex energy transfer processes.
