Charge transfer versus molecular conductance: molecular orbital symmetry turns quantum interference rules upside down.
Destructive quantum interference has been shown to strongly reduce charge tunneling rates across molecular bridges. The current consensus is that destructive quantum interference occurs in cross-conjugated molecules, while linearly conjugated molecules exhibit constructive interference. Our experimental results on photoinduced charge transfer in donor-bridge-acceptor systems, however, show that...
متن کاملWhen things are not as they seem: quantum interference turns molecular electron transfer "rules" upside down.
We present an interesting consequence of the differences between cross-conjugated and linearly conjugated molecules: the breakdown of conventional understanding of trends in molecular electron transfer. Interference effects are dominant in cross-conjugated molecules with unusual results: long molecules may have faster rates of electron transfer than short molecules, saturated molecules may have...

Observation of quantum interference in molecular charge transport.
As the dimensions of a conductor approach the nanoscale, quantum effects begin to dominate, and it becomes possible to control the conductance through direct manipulation of the electron wavefunction. Such control has been demonstrated in various mesoscopic devices at cryogenic temperatures, but it has proved to be difficult to exert control over the wavefunction at higher temperatures. Molecul...
