Abstract

original image

Finding the middle ground: A 1:1 host–guest complex consisting of a hexa-peri-hexabenzocoronene molecule sitting in the middle of the free cavity of a giant π-conjugated carbazole macrocycle has been obtained (see STM image). The complex has been prepared by physisorption of a monolayer of macrocycles followed by gas-phase deposition of graphene molecules by pulsed laser deposition.
