Structures and Properties of Saturn-Like Complexes Composed of Oligothiophene Macrocycle with Methano[60]fullerene and [70]Fullerene

Ď -Expanded oligothienylene macrocycle with a large inner cavity incorporates fullerenes such as methano[60]fullerene (C61H2) and [70]fullerene (C70) inside to form Saturn-like complexes. Although the oligothiophene macrocycle weakly interacts with fullerenes in solution, it forms stable Saturn-like fullerene complexes in the solid state. X-ray analysis of the Saturn-like complexes exhibited short contacts between the sulfur atoms of the oligothiophene macrocycle and fullerene-carbons, which hinder the rotation of fullerenes. As a result, the non-covalent interaction between the oligothiophene macrocycle and fullerenes was employed in crystal structure determination of fullerenes. UV-vis-NIR spectra of the Saturn-like complexes showed weak donor-acceptor interaction between the oligothiophene macrocycle and fullerenes.The accepted manuscript in pdf format is listed with the files at the bottom of this page.
