We developed a novel pathway to highly efficiently synthesize the [60]Fullerene (C60)-Cyclodextrin (CD) complex, which is termed as solvent-induced reversible recognition. Three kinds of typical complexes, namely, C60-2GUA+-α-CD, C60-2GUA+-β-CD and C60-4OH-β-CD, were synthesized. The chemical structure of all complexes was fully confirmed by Fourier transform infrared spectroscopy, Nuclear magnetic resonance (NMR), UV-Vis spectroscopy and the solubility test. Furthermore, crystalline status and thermal degradation were recorded by X-ray diffraction and Thermogravimetric analysis, respectively. Both the NMR and ESI-MS results clearly confirmed the 1:1 complex of C60 derivatives with CD. The pathway overcame the preparation limitation of traditional complex, and was extended to the prepare α-CD containing complex. To the best of our knowledge, it is the first time to report α-CD related complex. The geometric relation between C60 and CD for all the three kinds of complexes were analyzed. We can achieve high efficiency to obtain solid-state complex products, which lays the foundation for the widely practical application of complex and provides enough experimental basis for the advanced application of C60 and CD in supramolecular assembly. Notably, the solvent-induced reversibility and ionic instability of the complex provides a new possibility for the molecular recognition-based sensing.
