METALLIZATION OF POLYTHIOPHENES .4. INTERACTION OF VAPOR-DEPOSITED CUAND NI WITH ,2,2,3,3,4,4,5,5,6,6-TRIDECAFLUORONONYL)THIOPHENE] (P3TT)

This article deals with the X-ray photoelectron spectroscopy (XPS) stu dy of the interactions occurring during the formation of the interface between two transition metals, Ni and Cu, and the substituted polythi ophene, poly ,2,2,3,3,4,4,5,5,6,6-tridecafluorononyl)thiophene] (P3TT) . Ni was found to react to form both sulfide and fluoride. Cu was foun d to react mainly with S, forming only a negligible amount of fluoride . The results are consistent with the de-fluorination of the polymer s ubstituent and the resultant formation of an unsaturated or crosslinke d structure at the metal (Cu, Ni)/polymer interface.
