The cyclic host cyclo-[Pc-u](2) carrying two covalently connected Cu(II) porphyrin units can accommodate La@C-82, a paramagnetic endohedral metallofullerene, in its cavity to form the inclusion complex cyclo-[Pc-u](2)superset of La@C-82, which can be transformed into the caged complex cage-[Pc-u](2)superset of La@C-82 by ring-closing olefin metathesis of its side-chain olefinic terrnini. On the basis of electron spin resonance (ESR) and electron spin transient nutation (ESTN) studies, cyclo-[Pc-u](2)superset of La@C-82 is the first ferromagnetically coupled inclusion complex featuring La@C-82, whereas cage-[Pc-u](2)superset of La@C-82 is ferrimagnetic.
