Cross-conjugation increases the conductance of meta-connected fluorenones.
<p>Charge transport is strongly suppressed by destructive quantum interference (DQI) in <em>meta</em>-connected 1,1′-biphenyl-containing molecules, resulting in low electrical conductance. Surprisingly, we have found that DQI is almost entirely overcome by adding a bridging carbony...

| 总结: | <p>Charge transport is strongly suppressed by destructive quantum interference (DQI) in <em>meta</em>-connected 1,1′-biphenyl-containing molecules, resulting in low electrical conductance. Surprisingly, we have found that DQI is almost entirely overcome by adding a bridging carbonyl, to yield a cross-conjugated fluorenone. This contrasts with other π-systems, such as <em>para</em>-connected anthraquinone, where cross-conjugation results in low conductance.</p> |
