We have been able to "tune" the electrocatalytic activity of iron phthalocyanine (FePc) and hexadodecachlorophthalocyanine (16(Cl)FePc) for oxygen reduction reaction (ORR) by manipulating "pull effect" pyridinium molecules axially bounded complexes (FePcs). These axial ligands play both role molecular anchors also wires. The affect reactivity Fe metal center in phthalocyanine. originates from positive charge located on core. explored influence core positions (Up or Down), two structural...
Switching of conductance between conformers can be explained by the rotation one methyl group.
Abstract A conformationally flexible calix[4]pyrrole possessing a conjugated electronic structure (an N‐substituted oxoporphyrinogen (OxP) related to porphyrin) was used investigate the influence of mechanical stretching on single‐molecule conductance these molecules using mechanically‐controlled break junction (MCBJ) technique. The results show that molecule can be immobilized in configuration, giving rise different behaviours. These include step‐like features vs. displacement traces as...
Fullerenes have attracted interest for their possible applications in various electronic, biological, and optoelectronic devices. However, efficient use such devices, a suitable anchoring group has to be employed that forms well-defined stable contacts with the electrodes. In this work, we propose novel fullerene tetramalonate derivate functionalized trans-1 4,5-diazafluorene groups. The conductance of single-molecule junctions, investigated two different setups mechanically controlled break...

A classical reactivity descriptor in electrocatalysis is the binding energy of key intermediates to active sites. This well documented for catalytic activity metal electrodes [1], alloys and oxides less studied molecular catalysts [2]. The at constant potential plotted versus these descriptors has shape a volcano. explained by Sabatier principle, which states that there an optimum “bond strength” (not too strong, not weak) establishing best catalyst given reaction. Essentially one reacting...
