Abstract:
A supramolecular complex was constructed by encapsulation of a 3 O 2 molecule inside an open‐cage C 60 derivative. Its single‐crystal X‐ray diffraction analysis revealed the presence of the 3 O 2 at the center of the fullerene cage. The CV measurements suggested that unprecedented dehydrogenation was promoted by the encapsulated 3 O 2 after two‐electron reduction. The ESR measurements displayed the triplet character as well as the anisotropy of the 3 O 2 . Additionally, the SQUID measurements also demonstrated the paramagnetic behavior above 3 K without an antiferromagnetic transition. Upon photoirradiation with visible light, three phosphorescent bands at the NIR region were observed, arising from the exited 1 O 2 generated by self‐sensitization with the outer cage, whose lifetimes were not affected by the environments. These studies confirmed that the complex is a crystalline triplet system with incompatible “high spin density” but “small interspin interaction” properties.
