TL;DR: It is shown how a description of the local currents within a bridging molecule bound to metallic electrodes can provide chemical insight into current flow, and that interference effects can be characterized by the reversal of ring currents.

TL;DR: The concept of electronic coupling from theories of intramolecular electron transfer is extended and applied in the scattering theory (Landauer) formalism, which yields a simple sum over independent channels that is used to interpret and explain the unusual features of junction transport through cross-conjugated molecules and the differences among benzene rings substituted at the ortho, meta, or para positions.

TL;DR: The molecular design presented here provides a proof-of-concept for a quantum-interference-based approach to single-molecule insulators, engineered so that conduction is fully suppressed by σ quantum interference even for molecules less than a nanometre long, could prove useful in molecular-scale electronic circuitry.

TL;DR: These findings represent a new motif for electron transfer through molecules that exhibit both very high and very low tunneling conductance states accessible at low bias without nuclear motion, and allow a large dynamic range in conductance for single molecule electronic components.

TL;DR: The theoretical predictions and experimental conclusions agree that linearly conjugated AC is significantly more conductive than either cross-conjugated AQ or broken conjugate AH and that AQ and AH cannot necessarily be easily differentiated from each other.
