Rotaxane-branched radical dendrimers with TEMPO termini†
Abstract
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.
