Phenyleneethynylene Molecular Wires

Further, the investigation of the conduction behavior as a function of distance revealed nearly distant-independent charge-transfer characteristics [1]. These findings were corroborated by probing analogous systems containing porphyrins as electron donors instead of exTTF [2, 3].

The group of Professor Nazario Martin developed the synthesis of several donor-acceptor arrays containing -conjugated oPPEs of different length linking -extended tetrathiafulvalene (exTTF) as electron donor and C o as electron acceptor. Thereby, they systematically increased the length of the molecular wire from the monomer to the trimer. A detailed description of the corresponding synthesis is described elsewhere [8]. 

The structures of exTTF-oPPE -Cgo (9b—d) and the reference compounds used throughout the electrochemical and photophysical studies are represented in Fig. 9.1. 

Prior to any photophysical experiments, cyclic voltammetry experiments were performed with exTTF-oPPE -C6o 9b-9d and the reference compounds oPPE -Cgo 10. 11 to provide a vital impression of the energy-levels in these compounds.
