Single-molecule conductance in a unique cross-conjugated tetra(aminoaryl)ethene Medina Rivero, Sama García Arroyo, Paloma Li, Liang Gunasekaran, Suman Stuyver, Thijs Mancheño Real, María José Alonso, Mercedes Venkataraman, Latha Segura Castedo, José Luis Casado, Juan 547 Ciencias 23 Química A 1,1,2,2-tetrakis(4-aminophenyl)ethene with three paths of π-conjugation, linear-cis, linear-trans and a cross-conjugation, has been prepared. The molecule is able to bind to gold electrodes forming molecular junctions for single-molecule conductance measurements. Only two regimes of conduction are found experimentally. The modelling of the conductance allows to assign them to through-bond transmission in the linear case, while the cross-conjugated channel is further assisted by through-space transmission, partially alleviating the destructive quantum interference.
