title: Single-crystal nanoribbons, nanotubes, and nanowires from intramolecular charge-transfer organic molecules.
abstract: Single-crystal one-dimensional (1-D) nanostructures of [2-(p-dimethyl-aminophenyl)ethenyl]-phenyl-methylene-propanedinitrile (DAPMP) have been prepared by a simple solution process without the assistance of added surfactant, catalyst, or template under ambient condition. The approach exploits the directional supramolecular interaction induced by strong donor-acceptor dipole-dipole supramolecular interaction in the growth of 1-D nanostructures. By varying the process temperatures, the DAPMP nanostructures can be controllably prepared as either nanoribbons, nanotubes, or nanowires with high morphological and chemical purities. Significant changes in optical properties were observed for nanostructures of different morphology.
