X-ray photoelectron spectra of poly(3-hexylthiophene) (P3HT) films, metallized with vapor-deposited Cr, V and Ti, were used to study the nature of the metal-P3HT bonds formed with highly reactive metals. These metals cause similar changes in the S(2p) and C(1s) spectra. At coverages less than 3 Å, the spectral evidence indicates that metals react only with the sulfur atom of P3HT. At higher coverages, after the initial metal-S reaction, further reaction occurs between the already bonded metal and carbon.
