Monitoring and Exploiting Short-lived Intermediates in Assembly-Controlled Photocatalytic Processes (A05)

该项目旨在确定预组装物种的光谱特征，并在分子水平上从机械上了解这些特征在多大程度上能够实现新的光催化可能性。用时间分辨光谱研究了三种情况下预组装的前景：i)非共价底物-催化剂相互作用，ii)共价结合到具有催化活性的部分上的生色团，以及iii)有机自由基作为光催化剂。这些研究通过利用高压、电化学和磁场来加强，并通过与合成和理论的密切合作来补充。

The project aims to identify spectroscopic signatures of pre-assembled species and to mechanistically understand on a molecular level to which extent these enable new photocatalytic possibilities. The prospects of pre-assembly are investigated with time-resolved spectroscopy for three scenarios: i) non-covalent substrate-catalyst interactions, ii) chromophores covalently bound to a moiety exhibiting catalytic activity, and iii) organic radicals acting as photocatalysts. The studies are augmented by utilizing high pressure, electrochemistry, and magnetic fields, and are complemented by close collaboration with synthesis and theory.
