This Perspective highlights relationships between chemical features of metal bis(acetylide) complexes and their electrical response in a molecular junction.
The most probable single-molecule conductance of each member a series 12 conjugated molecular wires, 6 which contain either ruthenium or platinum center centrally placed within the backbone, has been determined. measurement small, positive Seebeck coefficient established that transmission through these molecules takes place by tunneling tail HOMO resonance near middle HOMO-LUMO gap in case. Despite general similarities lengths and frontier-orbital compositions, experimental computationally...
This paper describes the syntheses of several functionalized dihydropyrene (DHP) molecular switches with different substitution patterns. Regioselective nucleophilic alkylation a 5-substituted dimethyl isophthalate allowed development workable synthetic protocol for preparation 2,7-alkyne-functionalized DHPs. Synthesis DHPs surface-anchoring groups in 2,7- and 4,9-positions is described. The structures intermediates were elucidated by X-ray single-crystal diffraction. Molecular properties...
Indium tin oxide (ITO) is an attractive substrate for single-molecule electronics since it transparent while maintaining electrical conductivity. Although has been used before as a contacting electrode in studies, these studies have limited to the use of carboxylic acid terminal groups binding molecular wires ITO substrates. There thus need investigate other anchoring with potential effectively ITO. With this aim, we investigated conductance series eight tolane or “tolane-like” variety...
Controlling the orientation of complex molecules in molecular junctions is crucial to their development into functional devices. To date, this has been achieved through use multipodal compounds (i.e., containing more than two anchoring groups), resulting formation tri/tetrapodal compounds. While such have greatly improved control, comes at cost lower surface coverage. In study, we examine an alternative approach for generating multimodal by binding multiple independent wires together metal...
