Down to the wire : Pentacene exhibits crystal‐plane‐dependent photoluminescence (PL) activity, as demonstrated in highly crystalline 1D wires and 2D disks, which were selectively synthesized using the vaporization–condensation–recrystallization (VCR) process. Although pentacene 1D wires and 2D disks have identical triclinic crystal structures, PL activity is observed only from pentacene 1D wires owing to the presence of “PL‐active” (010) planes.
