Syntheses of novel fullerene tweezers and their supramolecular inclusion complex of C60

Article abstract of DOI:10.1246/cl.1998.1099

Fullerene tweezers which have a rigid acetylenic spacers were synthesized and their inclusion abilities for C₆₀ were examined by UV spectroscopy. From the spectra, the association constants were determined using Benesi-Hildebrand method. Fullerene tweezers with a 1,4-bis(4-oxycarbonylphenyl)butadiyne spacer showed the highest association constant for C₆₀ (39300±250 dm³mol^-1 in benzene).
