Exceptionally Small Attenuation Factors in Molecular Wires

摘要

The potential of molecular-sized materials for electronic and photonic applications has led to an ever increasing interest in developing and probing molecular-scale wires.1 -Conjugated oligomers, such as oligo (p-phenylenevinylenes) (oligo-PPVs), are among those molecules which act as efficient molecular wires.2,3 Despite this interest, only a few reports on electron transfer through the -conjugated chains of oligo-PPVs are known.4 In this light, the importance of energy matching between the donor and bridge components, for achieving molecular-wire behavior, has been highlighted.
