Abstract
A highly water-soluble [60]fullerene inclusion complex bicapped with ethylenediamino-β-cyclodextrin was prepared, which was further used to construct uniform cubical microstructure with poly (acrylic acid). The formation of the inclusion complex was confirmed by NMR studies. The analysis of X-ray photoelectron spectroscopy and thermogravimetric analysis data revealed that the fullerene molecule was bicapped with β-cyclodextrin. The self-assembly of [60]fullerene inclusion complex with poly (acrylic acid) was investigated by UV-Vis spectroscopic titrations, supporting a 1:1 monomeric units binding model and yielding a complex stability constant of 9.8 × 103 M− 1. The cubical microstructure formed was proved to be a crystalline structure by transmission electron spectroscopy measurements.
