Exploring protonation sites with cation-responsive polyethylene glycol (PEG) tethers in [FeFe]-hydrogenase mimics
Na + and K + coordination influence protonation of [FeFe]H 2 ase mimics with polyether-linked triazoles. In TFA protonated triazoles avoid K + , boosting TOF, while Na + keeps coordination lowering activity. This insight aids in the design of HER catalysts.
