Polycyclic aromatic hydrocarbons (PAHs) show promise for applications in functional devices such as organic photovoltaics and field-effect transistors, but, although nanometer-sized PAHs-often referred to as nanographenes-have been well investigated as single-layer mols., their multilayer counterparts remain rather unexplored. Here we show the assembly of a C64 nanographene derivative (comprising a planar core decorated with four meta-terphenyl-imide moieties at its periphery) into multilayer stacks with smaller PAHs ranging from naphthalene to ovalene and hexabenzocoronene. The functionalized C64 nanographene serves as a ditopic host that can accommodate a smaller PAH on either side of its planar core, in cavities delimited by its bulky imide substituents. Bilayers and trilayers (i.e., complexes with 1:1 and 1:2 host:guest ratios, resp.) were observed in solution, and dimers of these complexes as well as multilayer compounds were isolated in the solid state. Quantum-chem. calculations indicate that dispersion forces are the main stabilizing factor for these complexes.
