We present and discuss the performance of H electron-nuclear double resonance (ENDOR) at 263 GHz/9.4 T by employing a prototype, commercial quasi optical spectrometer. Basic instrumental features of the setup are described alongside a comprehensive characterization of the new ENDOR probe head design.

This report describes properties of NHY of key importance for its application in mechanistic studies. By combining the tRNA/NHY-RS suppression technology with a model protein tailored for amino acid redox studies (αX, X = NHY), the formal reduction potential of NHY(O/OH) ( E°' = 395 ± 7 mV at pH 7.

- Photon-powered charge separation is achieved through self-assembled dimers of coordination cages made from redox-active chromophores, synthesized simply using available ligands and Pd(II) cations.
- The study compared the properties of pure cages, mixtures of donor and acceptor cages, and mixed-ligand cages using various spectroscopic techniques, revealing that only the mixed-ligand cages showed effective electron transfer upon excitation.
- This research highlights the potential for densely packed self-assemblies to enhance charge separation in photovoltaic applications, suggesting they may provide better control over the charge separation layer's structure at the molecular level.
