Faster interfacial electron transfer: the effect of molecule shape and size

点击翻译按钮获取中文摘要

This project aims to explore the effect of shape and size of pi-conjugated molecules on interfacial electron transfer reactions, which are fundamentally important in all applications of photo-electrochemical conversion and storage of energy. By making two series of pi-conjugated molecules and determining electron transfer rates using a combination of transient spectroscopies and computational chemistry, the project expects to generate new design principles for molecules with the potential to significantly improve the efficiencies of solar energy conversion and photo-catalytic processes. The new materials and findings will be exploited in a novel redox-mediated water splitting device as a practical outcome with potential end user benefits.
