The precise synthesis of novel rotaxane-branched radical dendrimers Gn-TEMPO ( n = 1-3) with up to 24 TEMPO radicals as termini was successfully achieved, from which nanoparticles with a good longitudinal relaxivity were further prepared, thus making them potential candidates as promising contrast agents for magnetic resonance imaging.
