A methylrhodium(III) porphyrin cyclic dimer was found to form supramolecular oscillators with fullerene homo and hetero dimers such as C_<120> and C_<130>, where included fullerenes oscillate back and forth within the porphyrin dimer iso- and anisotropically, respectively, without dissociation. From thermodynamic analysis of the oscillation processes via simulation of VT-NMR spectral profiles of the complexes and saturation transfer experiments, these oscillations are found to be entropy-driven and retarded by the solvent-fullerene interactions.From SQUID and 2D-ESR measurements, ferromagnetic coupling of spins between paramagnetic copper porphyrin cyclic dimers and La@C_<82> was found upon complextaion of the host and guest molecules, while the dimer alone or with diamagnetic C_<60> does not show any interaction of the spins at the host molecules.

发现一种甲基头（III）卟啉环状二聚体形成具有富勒烯同型和杂型二聚体的超分子振荡器，例如C_ <120>和C_ <130>，其中包括富勒烯酸酯在卟啉二聚体二聚体二聚体ISO-和Anisotroproproproploploplotine oscillate上振荡没有解离。通过模拟复合物和饱和转移实验的VT-NMR光谱谱的振荡过程的热力学分析，发现这些振荡是由熵驱动的，并通过溶剂 - 富勒烯相互作用延伸。在宿主和宾客分子的complextaion时，发现了顺磁铜卟啉环蛋白环蛋白环蛋白环蛋白环蛋白之间的偶联。
