Abstract:
Covalent immobilization of TEMPO at carbon and gold via an aliphatic -(CH2)6- linker was achieved via cathodic grafting of a diamagnetic precursor, tetramethylpiperidine, with subsequent >NH to >NO oxidation to give TEMPO-capped paramagnetic interfaces (ΓTEMPO = 5.2 × 10-10 mol cm-2); catalytic and spin switching potential of the thus prepared systems was demonstrated.
