Tuning electron transfer through p-phenyleneethynylene molecular wires

Abstract

Weak wire-like behavior-with a damping factor (beta) of 0.2 +/- 0.05 A(-1)--has been found in a series of C60-wire-exTTF systems (i.e., p-phenyleneethynylene): these results contrast with previous observations involving p-phenylenevinylene systems.
