Doping of poly(cyclophosphazene-benzoquinone) films with polyiodide
- Pacific Northwest National Lab., Richland, WA (United States); and others
Polyiodide is inserted into poly(cyclophosphazene-benzoquinone) (PPBQ) film from solution or vapor phase as a result of a charge-transfer interaction between the quinone oxygen and iodine. The incorporation of the polyiodide into the PPBQ film enhanced ion (or electron) transport in the film. Characterization of the PPBQ film before and after polyiodide doping with X-ray photoelectron, UV/vis and Raman spectroscopy indicates that the doping mechanism is governed by the formation of a charge-transfer complex. Raman spectra of PPBQ films suggest that polyiodide interacts with the oxygen atoms in the P-O-C linkage, where the phosphorus atom is part of the phosphazene trimer and the carbon atom is part of the aromatic ring. This is the first direct evidence for the bonding arrangement of iodine in a poly(cyclophosphazene) system. 28 refs., 10 figs., 1 tab.
