Influence of functionalized substituents on the light-induced electron-transfer abilities of entatic copper guanidinequinoline complexes

The fundamental scientific question, addressed in the current proposal is the interplay between structural and electronic degrees of freedom, their constraints and their role in improving electron transfer (ET) properties in Cu complexes. We aim at disentangling structural and electronic effects by studying model complexes with dominating influence of one or the other type of modification. Even though the changes of different nature are applied, they lead to a similar improvement in ET abilities compared to the unmodified complex. Unique capability of ID09 beamline to combine structurally sensitive Wide-angle X-ray scattering (WAXS) and electronically sensitive X-ray emission spectroscopy (XES) will allow separating and resolving the effects of structural and electronic constraints.
