We focus on aggregated structures and charge-transporting properties in semiconductor assemblies of a new-type twisted π-conjugated molecule, dinaphtho[2,1-b:1′,2′-d]furan (DNF-U). Single crystals were successfully grown by physical vapor transport to form a two-dimensional herringbone packing structure, which is advantageous for intermolecular charge transport. Based on the packing structure, relatively large transfer integrals were theoretically calculated to be 20 and 57 meV for C–H···π and π···π direction, respectively. The single-crystal field-effect transistors exhibited notable hole mobility of up to 1.0 cm2 V−1 s−1.
