“…In the context of the P3ATs, the recent developments in the processability of these conjugated polymers has lead to better science being done on these materials. In the case of the polythiophenes, electrochemically made poly thiophene (PT) [49] and poly(3-methylhiophene) [50] have been studied some years ago. More recently, the P3ATs, and in particular poly(3-hexylthiophene) (P3HT), has been studied more extensively by the same methods, employing high-quality, ultra-thin, solution-cast films, enabling much better spectra to be obtained, as discussed below.…”

ABSTRACf. The poly(3-alkylthiophenes) represent a new generation of conducting polymers, that exhibit both solution and melt processability. These properties open new possibilities for the utilization of conducting polymers in practical applications. Furtheonore, the solubility of these polymers enables the characterization of the physical and chemical structure in greater detail than hitherto have been possible. In this chapter we give a brief review of the synthetic routes to the poly(3-alkylthiophenes) as well as an overview of some of the recent results on the physical and chemical characterization of this class of materials. In this overview we include results on stability properties, transport properties, thermo-and solvatochromism. We also discuss some aspects of the utilization of the poly(3-alkylthiophenes) in applications.

“…Similar to polythiophene, 40 the highest occupied band in PE-DOT arises from the overlap of the molecular orbitals of EDOT units, that have a strong contribution on the C ␣ carbon atoms, but none on the sulfur atom ͑see Fig. 6, HOMO-1͒.…”

The electronic structure of a series of phenyl-capped 3,4-ethylenedioxythiophene oligomers has been studied using ultraviolet photoelectron spectroscopy ͑UPS͒ in combination with theoretical calculations. The calculations were performed for isolated oligomers within the framework of density-functional theory, using the BeckeϩLee-Yang-Parr exchange-correlation functional. Excellent agreement between the UPS spectra and the quantum-chemical calculations allowed for unambiguous interpretation of the results. We use the asymptotic extension of electronic properties of oligomers to discuss the electronic structure of neutral poly͑3,4-ethylenedioxythiophene͒. In addition, experimentally determined ionization potentials for thin films prepared by vapor deposition and spin coating are reported, and are found to depend on the preparation method. The discrepancy is assigned to differences in the molecular packing.
