Crystal-plane-dependent photoluminescence of pentacene 1D wire and 2D disk crystals.
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.
