Single-Molecule Conductance of 1,4-Azaborine Derivatives as Models of BN-doped PAHs Palomino-Ruiz, Lucía Rodríguez-González, Sandra Fallaque, Joel G. Rodríguez Márquez, Irene Agraït, Nicolás Díaz, Cristina Leary, Edmund Cuerva Carvajal, Juan Manuel González Campaña, Araceli Martín, Fernando Millán, Alba González, M. Teresa The single–molecule conductance of a series of BN-acene-like derivatives has been measured by using scanning tunneling break-junction techniques. A strategic design of the target molecules has allowed us to include azaborine units in positions that unambiguously ensure electron transport through both heteroatoms, which is relevant for the development of customized BN-doped nanographenes. We show that the conductance of the anthracene azaborine derivative is comparable to that of the pristine all-carbon anthracene compound. Notably, this heteroatom substitution has also allowed us to perform similar measurements on the corresponding pentacene-like compound, which is found to have a similar conductance, thus evidencing that B–N doping could also be used to stabilize and characterize larger acenes for molecular electronics applications. Our conclusions are supported by state-of-the-art transport calculations. 2022-09-09T08:09:02Z 2022-09-09T08:09:02Z 2021 info:eu-repo/semantics/article http://hdl.handle.net/10481/76592 10.1002/anie.202014194 eng http://creativecommons.org/licenses/by-nc-nd/4.0/ info:eu-repo/semantics/openAccess Attribution-NonCommercial-NoDerivatives 4.0 Internacional
