Two-dimensional, phenanthroline-based, extended π-conjugated molecules for single-molecule conduction
The conduction properties of phenanthroline-terminated, polycyclic extended rr -conjugated molecul ar wires are investigated using density fun ctional theory (OFT) in combination with Green 's function techniques and group theory. While these molecules could possibly be thought of as accessible graphene-like fragments, they are calculated to conduct poorly. The decay constant for their exponent...
متن کاملBoron-mediated sequential alkyne insertion and C–C coupling reactions affording extended π-conjugated molecules
C-C bond coupling reactions illustrate the wealth of organic transformations, which are usually mediated by organotransition metal complexes. Here, we show that a borafluorene with a B-Cl moiety can mediate sequential alkyne insertion (1,2-carboboration) and deborylation/Csp(2)-Csp(2) coupling reactions, leading to aromatic molecules. The first step, which affords a borepin derivative, proceeds...
متن کاملProgrammed self-assembly of large π-conjugated molecules into electroactive one-dimensional nanostructures.
Electroactive one-dimensional (1D) nano-objects possess inherent unidirectional charge and energy transport capabilities along with anisotropic absorption and emission of light, which are of great advantage for the development of nanometer-scale electronics and optoelectronics. In particular, molecular nanowires formed by self-assembly of π-conjugated molecules attract increasing attention for ...
متن کاملImportance of direct metal-π coupling in electronic transport through conjugated single-molecule junctions.
We study the effects of molecular structure on the electronic transport and mechanical stability of single-molecule junctions formed with Au point contacts. Two types of linear conjugated molecular wires are compared: those functionalized with methylsulfide or amine aurophilic groups at (1) both or (2) only one of its phenyl termini. Using scanning tunneling and atomic force microscope break-ju...
متن کاملUnderstanding the Assembly of π-Conjugated Dithiol Molecules on GaAs
Introduction The assembly of alkane-based molecular layers on metals (e.g. Au, Ag, Pt) and, to a smaller extent, on semiconductors (e.g. GaAs, Si) has been investigated in detail. Such chemistries, although potentially valuable in surface engineering and patterning, cannot facilitate charge transport on the molecular level due to their backbone saturation. On the other hand, π-conjugated system...
