Pre-association between photocatalyst and substrate is a crucial advantage for a photocatalytic reaction, as the potential losses associated with diffusion-limited steps are avoided. Proving such pre-association under synthetically relevant conditions can be difficult. We will implement and apply novel spectroscopic tools to prove and improve pre-association in photocatalytic reactions in collaboration with partners from theory and synthesis. The methods of choice are multiscale transient absorption – from femtoseconds to microseconds – and transient absorption anisotropy.
