Single?Molecule Conductance of 1,4?Azaborine Derivatives as Models of BN?doped PAHs

The single-molecule conductance of a series BN-acene-like derivatives has been measured by using scanning tunneling break-junction techniques. A strategic design the target molecules allowed us to include azaborine units in positions that unambiguously ensure electron transport through both heteroatoms, which is relevant for development customized BN-doped nanographenes. We show anthracene derivative comparable pristine all-carbon compound. Notably, this heteroatom substitution also perform similar measurements on corresponding pentacene-like compound, found have conductance, thus evidencing B-N doping could be used stabilize and characterize larger acenes molecular electronics applications. Our conclusions are supported state-of-the-art calculations.
