We report a molecular design that provides an intravenously injectable organic radical contrast agent (ORCA) that has molecular r1 ≈ 5 mM−1s−1. The ORCA is based on spirocyclohexyl nitroxide radicals and polyethylene glycol chains conjugated to a generation 4 polypropylenimine dendrimers scaffold. The metal-free ORCA has a long shelf-life and provides selectively enhanced MRI in mice for over 1 h.
