Bowl inversion is aunique property of buckybowls. The polarity and assembly configuration of buckybowls are reversed after bowl inversion. So far,this unique phenomenon has been studied in solution and on surface,b ut not in solid state due to spatial constraint. Now as eries of exo-type supramolecular assemblies of trithiasumanene and nanographene are investigated. Tuning the electron density of the nanogaphene component was found to directly affect the binding constant of the complex. Reversible bowl inversion in the solid state was then successfully achieved by subjecting the trithiasumanene-nanographene assembly with the weakest binding strength to repeated heating-cooling cycles,w hich was unambiguously observed by single crystal X-ray diffraction.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
