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.
