The aim of this project is to relate efficient energy and electron transfer processes in molecular materials to the presence of quantum coherences. The ongoing debate on the role of quantum coherences in the efficient harvesting of sunlight of photosynthesis appears to be limited by the complexity of the biological systems and a lack of high instrumentation sensitivity. Using molecular systems and a highly sensitive method, this project aims to reveal the effects of molecular conformation and geometry on quantum coherences. The outcome is likely to improve our understanding of nature's remarkable ability to harvest energy efficiently from the sun and foster new approaches that increase the efficiency of light-harvesting systems.

这个项目的目的是将分子材料中的有效能量和电子转移过程与量子相干性的存在联系起来。目前关于量子相干性在光合作用有效收获阳光中的作用的争论似乎受到生物系统复杂性和缺乏高仪器灵敏度的限制。利用分子系统和高灵敏度的方法，该项目旨在揭示分子构象和几何形状对量子相干性的影响。这一结果可能会提高我们对大自然从太阳有效获取能量的非凡能力的理解，并促进提高光收集系统效率的新方法。
