Abstract

original image

Stack it up: Reduction of corannulene with an excess of lithium metal in dimethoxyethane (DME) results in the formation of remarkable multilayered supramolecular aggregates (see picture) having lithium alkoxo nanobelts encapsulated between two tetrareduced corannulene bowls, [C20H104−/Li6(OR)6Li6/C20H104−]2−. The alkoxo groups (R=CH3O or/and CH3OCH2CH2O) are products of the Li-induced DME cleavage.
