Furthermore, we extend the system to a more realistic nanowire complex shown below in which the polyacetylene of above example was replaced by head-to-tail coupled polythiophene derivatives—[oligo(2,5-thienylene-ethynylene)-](OTE)-terminated by the same fullerene and H2TPP. The OTE wire part is a class of conjugated oligomers with a high shape-persistence as rigid rods and special attention is focused on the systems with terminal donor-acceptor substitution because of a strong push-pull effect [57-59].
