In this study, we report on the synthesis of Ir\u2010doped Au\n                    <jats:sub>12<\/jats:sub>\n                    (Ir@Au\n                    <jats:sub>12<\/jats:sub>\n                    ) icosahedral clusters functionalized with two open\u2010shell verdazyl radicals at opposite poles, along with an investigation into their electronic, magnetic, and photophysical properties. The photoluminescence from the Ir@Au\n                    <jats:sub>12<\/jats:sub>\n                    cluster core is drastically quenched by the introduction of verdazyl ligands. The ultrafast time\u2010resolved absorption spectroscopy reveals the electron transfer from the Ir@Au\n                    <jats:sub>12<\/jats:sub>\n                    core in the triplet excited state to the verdazyl ligand. The EPR study discloses the hyperfine coupling with the Au and Ir nuclei, indicating the spin density of the verdazyl radical moderately delocalized over the Ir@Au\n                    <jats:sub>12<\/jats:sub>\n                    core. These results provide direct evidence of electronic interaction between the organic radicals and Ir@Au\n                    <jats:sub>12<\/jats:sub>\n                    superatomic core.

These findings will establish superatom\u2013organic radical hybrids as a new class of multi\u2010spin systems and provide a design strategy for photofunctional and magnetic nanomaterials based on
