As the field of mol.-scale electronics matures and the prospect of devices incorporating mol. wires becomes more feasible, it is necessary to progress from the simple anchor groups used in fundamental conductance studies to more elaborate anchors designed with device stability in mind. This study presents oligo(phenylene-ethynylene) wires with one tetrapodal anchor and a Ph or pyridyl head group. The new anchors are designed to bind strongly to Au surfaces without disrupting the conductance pathway of the wires. Conductive probe at. force microscopy (cAFM) was used to determine the conductance of self-assembled monolayers (SAMs) of the wires in Au-SAM-Pt and Au-SAM-graphene junctions, from which the conductance per mol. was derived. For tolane-type wires, mean conductances per mol. of up to 10-4.37 G0 (Pt) and 10-3.78 G0 (graphene) were measured, despite limited electronic coupling to the Au electrode, demonstrating the potential of this approach. Computational studies of the surface binding geometry and transport properties rationalize and support the exptl. results. The experimental process involved the reaction of 4-Ethynylpyridine(cas: 2510-22-7Application of 2510-22-7)
4-Ethynylpyridine(cas: 2510-22-7) belongs to pyridine. Pyridines are often used as catalysts or reagents; particular notice has been paid recently to how pyridine coordinates to metal centers enabling a wide range of valuable reactions. Application of 2510-22-7
