Biaxial aromatics with face-on/edge-on stacking adaptability: an STM/STS study of 1D nanowires assembled via rotatable ethynyls.
نویسندگان
چکیده
Scanning tunnelling microscopy/spectroscopy reveals significant electronic communications between edge-on biphenyl moieties of a benzene core derivatised biaxially with four ethynyl-biphenyls. The key to the successful assembly of conjugated 1D nanowires is the rotatable features of ethynyls, which allow dual adaptability of edge-on and face-on orientations for the aromatic rings.

1D organic semiconductor wires are currently emerging as building blocks for various electronic and optical applications such as field effect transistors, light emitting diodes, photoswitches, vapor sensors and optical waveguides. Conventional fabrication methods for 1D organic nanowires are broadly categorized as either solution-based or surface-supported self-assembly. Solution-based self-ass...
متن کاملUltralong nanobelts self-assembled from an asymmetric perylene tetracarboxylic diimide.
One-dimensional (1D) self-assembly of planar aromatic (semiconductor) molecules into well-defined nanowires or nanobelts has gained increasing interest1 since such an approach may extend the optoelectronic properties and applications intrinsic to organic semiconductors from film-based materials into the size ranges and architectures that have never before been achieved. Among the small number o...
متن کاملOne-dimensional organic nanostructures: A novel approach based on the selective adsorption of organic molecules on silicon nanowires
Scanning tunneling microscopy (STM) is used to investigate the formation of one-dimensional organic nanostructures by chemisorption of specific molecules on silicon nanowires. STM data demonstrate that depending on the molecular functional groups, the molecules adsorb either randomly on the substrate or preferentially on the nanowires. In the latter case, chemisorption of suitable organic molec...

In this study, the free vibration behavior of orthotropic rectangular graphene sheet embedded in an elastic medium under biaxial pre-load is studied. Using the nonlocal elasticity theory, the governing equation is derived for single-layered graphene sheets (SLGS). Differential quadrature method (DQM) has been used to solve the governing equations for various boundary conditions. To verify the a...
