“…In particular, we prepared co‐crystals with fullerenes. Supramolecular complexes between porphyrin moieties and (C60‐Ih)[5,6]fullerene (C 60 ) (and/or fullerene derivatives) have been studied in detail from the viewpoints of the crystal and electronic structures (see Scheme S1 in the Supporting Information) . In fullerene‐porphyrin systems, close contact between molecules and selective supramolecular interactions occur.…”

A supramolecular complex (1⋅C60) was prepared by assembling (C60‐Ih)[5,6]fullerene (C60) with the dinuclear Tb3+ triple‐decker complex [(TPP)Tb(Pc)Tb(TPP)] (1: Tb3+=trivalent terbium ion, Pc2−=phthalocyaninato, TPP2−=tetraphenylporphyrinato) with quasi‐D4h symmetry to investigate the relationship between the coordination symmetry and single‐molecule magnet (SMM) properties. Tb3+‐Pc triple‐decker complexes (Tb2Pc3) have an important advantage over Tb3+‐Pc double‐decker complexes (TbPc2) since the magnetic relaxation processes correspond to the Zeeman splitting when there are two 4f spin systems. The two Tb3+ sites of 1 are equivalent, and the twist angle (φ) was determined to be 3.62°. On the other hand, the two Tb3+ sites of 1⋅C60 are not equivalent. The φ values for sites Tb1 and Tb2 were determined to be 3.67° and 33.8°, respectively, due to a change in the coordination symmetry of 1 upon association with C60. At 1.8 K, 1 and 1⋅C60 undergo different magnetic relaxations, and the changes in the ground state affect the spin dynamics. Although 1 and 1⋅C60 relax via QTM in a zero applied magnetic field (H), H dependencies of the magnetic relaxation times (τ) for H>1500 Oe are similar. On the other hand, for H<1500 Oe, the τ values have different behaviors since the off‐diagonal terms (Bkq;q≠0 ) affect the magnetic relaxation mechanism. From temperature (T) and H dependences of τ, spin‐phonon interactions along with direct and Raman mechanisms explain the spin dynamics. We believe that a supramolecular method can be used to control the magnetic anisotropy along the C4 rotation axis and the spin dynamic properties in dinuclear Ln3+‐Pc multiple‐decker complexes.

“…Fullerene (C 60 ) and its derivatives have been widely used in many fields owing to their unique physical and chemical properties . Furthermore, it is one of the elemental forms of carbon which has great potential for being a high‐capacity hydrogen‐storage material, and possible catalyst for hydrogenation reactions with special catalytic activity due to its unique molecular structure .…”

Metal nanoparticles (NPs) stabilized by MOFs are very promising for catalysis, whereas introduction of C into MOFs has been very rarely used, and there was no report for their cooperative catalysis in organic syntheses. In this work, C @UiO-67 was synthesized by a one-pot method, so that C is uniformly distributed on UiO-67 in molecular form. Pd NPs coordinating with C have been successfully embedded into the framework. The obtained multifunctional C Pd @UiO-67 catalyst exhibits remarkable synergistic catalytic activity in cascade reactions under mild conditions, where UiO-67 affords Lewis acidity and C Pd offers higher hydrogenation activity relative to solely Pd NPs.
