inter-spin distances between 1.4 and 4 nm and their room temperature continuous wave (CW) EPRspectra are reported. Conditions for attachment of the spin-label via esterification have been optimized on the direct synthesis of polyradicals from commercially available polyphenols and the carboxylic acid functionalized nitroxide TPC. A common synthetic protocol utilizing 4-hydroxy-4′-iodobiphenyl as a key building
