Hybrid thin films containing N,N'-bis(2-phosphonoethyl)-1,4,5,8-naphthalenediimide (PNDI) and zinc cations (PNDI/Zn films) were built on silicon and indium tin oxide (ITO) substrates by a simple layer-by-layer deposition process. Silicon substrates primed with a layer of phosphonate groups were immersed alternately into zinc nitrate and PNDI aqueous solutions, yielding PNDI/Zn films containing up to 40 layers. ITO substrates, on the other hand, were used without priming, and the deposition sequence began with a PNDI layer. All film gr
