Metallization of polythiophenes II. Interaction of vapor-deposited Cr, V and Ti with poly(3-hexylthiophene) (P3HT)

Abstract We have studied the chemical structure and the nature of the reaction at the interfaces between a semiconducting conjugated polymer, poly(3-hexylthiophene) (P3HT), and the three coinage metals: Cu, Ag and Au. The initial stages of interface formation were followed, with the type and extent of chemical reaction being determined by XPS. It is found that both Cu and Ag react exclusively at the S atom of the P3HT while Au does not appear to reaact at all.
