X-ray photoelectron spectroscopy (XPS) sputter depth profiling of Ag-doped poly[Fe( 4-vInyi-4’-methyl-2,2‘-bipyrldyi),(CN ),]-poly( 4-vlnyi-4’-methyl-2,2‘-blpyrldyi) is descrlbed. These conductive polymer films are doped with Ag’ via soaking, and the distribution and oxldation stale of the Ag dopants are modified by electrochemical reductlon. XPS is evaluated for Its ablilty to quantitatively profile the Induced concentratlon gradients of Ag sites (
