摘要

Designed synthesis of a new crystalline donor–acceptor organic hybrid has been accomplished by using two bowl-shaped polycyclic aromatic hydrocarbons (PAHs) having complementary structures and properties, namely, C20H10 and C5-C20H5(CF3)5. The X-ray structural characterization of the product, [(C20H10)·(C20H5(CF3)5)]·C6H4Cl2, revealed the formation of aligned columnar stacks of alternating C20H10 and C20H5(CF3)5 molecules with centroid-to-centroid distances of 3.658(8) and 3.787(8) ? and a small bowl slip of 0.086(6) ?. The tight bowl packing is accompanied by notable molecular geometry adjustments of the individual PAHs. The bowl depth increased for corannulene (Δ = +0.019 ?) and decreased for sym-pentakis(trifluoromethyl)corannulene (Δ = ?0.011 ?), facilitating enhancement of concave–convex interactions along the stacks. The parallel alignment of one-dimensional columns is supported by multiple intermolecular interactions involving C6H4Cl2 used as the crystallization solvent, forming an infinite two-dimensional network in the solid state.]]>
