ABSTRACT
Electron transfer is of fundamental importance in many areas of
chemistry and biochemistry [1]. The ability to transfer charge
efficiently over distances in the 10 nm range is crucial in vari-
ous practical devices, such as organic transistors and solar cells-
both dye-sensitized metal oxide solar cells and bulk-heterojunction
blend devices [2]. Furthermore, in the context of the ever-decreasing
dimensions of integrated circuits, it is interesting to study charge
transport through individual molecules [3]. Organic π -conjugated
oligomers and polymers are attractive candidates as molecular
wires, because modern synthetic chemistry can be used to create
almost any type of π -conjugated backbone, while non-covalent
interactions and supramolecular chemistry can be used to modify
the backbone conformation. Interactions of conjugated oligomers,
both with each other and with the external environment, can
also be controlled by self-assembly and non-covalent encapsulation
[4].
