“…From further atomic concentration analysis, the experimental composition of a bilayer unit was found to be in agreement with the expected one [37]. The group of Manners compared the XPS spectra of LBL superlattices made of different bilayer numbers [36]. The results illustrated that the region for Fe (2p) increased in relative intensity with multilayer buildup, confirming the successful incorporation of PFS units into the thin film structure.…”

“…Before the development of fully organometallic multilayers, examples based on organic polymers and organometallic PFS were first shown around the year 2000 [19,36]. In these examples, cationic PFS polyelectrolytes (3, 5, 6) were used, while for the anionic polyelectrolyte species poly(styrene sulfonate) (PSS) or poly(sodium vinylsulfonate) were chosen.…”

“…The successful exploration of these hybrid multilayer thin films was soon extended to the fabrication of fully organometallic superlattices solely composed of PFS polyelectrolytes. Multilayers were deposited on (but are not restricted to) quartz slides, silicon wafers, gold substrates, and quartz crystal microbalance substrates [36][37][38]. For gold substrates, normally a predeposited thiol monolayer (such as sodium 3-mercapto-1-propanesulfonate, 11-mercaptoundecanoic acid, or 2-aminoethanethiol hydrochloride) was applied to impart negative or positive charges to the surfaces.…”

“…The fitting gave a thickness value of 0.4 nm for the contribution of a single bilayer. Thicker films (with bilayer thicknesses up to $5 nm) were also prepared by varying the ionic strength of the polyelectrolyte solutions from which the layers were deposited [34,36,[41][42][43]. Very recently, we carried out a systematic study on PFS multilayer deposition from aqueous solutions with varying ionic strength and polymer concentrations.…”

New frontiers in polymer science involve the incorporation of functional species into material systems. The electrostatic layer-by-layer (LBL) self-assembly technique constitutes a versatile tool for nano-and microscale fabrication of devices and novel material structures. Although a rapidly growing attention has been paid to this area, most of the studies conducted were based on organic polymeric electrolytes. Due to synthetic developments, new polymeric structures with inorganic elements and transition metals incorporated in the main chain have become accessible. With the development of new synthesis routes, organometallic poly(ferrocenylsilane) polycations and polyanions emerged. Their charged nature and water-solubility made them excellent candidates for the extension of electrostatic multilayer assembly to organometallic polymeric materials. The present review gives a concise summary on the LBL fabrication of organometallic thin films and microcapsules based on water-soluble poly(ferrocenylsilane) polyions. The unique functions of these structures come from the molecular structure of poly(ferrocenylsilanes), in which silicon atoms and redoxactive ferrocene units are present. In this context, the diverse application potentials of these organometallic multilayer structures are also discussed.

“…This yielded regularly stacked, homogeneous electrostatic superlattices. 173 In another study, poly(ferrocenyl(3-ammoniumpropyl)methylsilane) was used in conjunction with poly(sodium vinylsulfonate) to form a multilayer film on quartz. 69 It was noted that a linear relationship between optical absorbance and the number of bilayers was indicative of the formation of well-defined multilayers.…”

The thermal ROP route requires the synthesis and careful purification of the cyclic trimer [Cl 2 PN] 3 and the use of elevated temperatures where control of molecular weight is very difficult and cross-linking can take place at high conversion, which can limit the yield. INORGANIC POLYMERSVol. 3to phosphazene polymers, which may well facilitate more rapid and extensive commercialization.Monomer Synthesis. Both the ROP and condensation routes to poly(dichlorophosphazene) require high purity monomers. For the traditional ROP process, ultrahigh purity [NPCl 2 ] 3 is required. The most common method for its preparation is through the reaction of PCl 5 with NH 4 Cl in a high boiling halogenated solvent, such as chlorobenzene or tetrachloroethane, at 150 • C. The yields can approach 70-80% under specialized conditions, but 50% is more typical (25). The phosphoranimine most commonly used in the aforementioned condensation route to poly(dichlorophosphazene) is Cl 3 P NSi(CH 3 ) 3 . The synthesis of this compound has been described (21) and is based on a modification of an earlier procedure (26) involving the reaction of PCl 5 with LiN(Si(CH 3 ) 3 ) 2 at −78 • C in hexane. However, the purification required by this method is a challenge and leads to an overall yield of <40%.It has also been reported that the reaction of N(Si(CH 3 ) 3 ) 3 with PCl 5 can be manipulated to maximize yields of either the cyclic trimer (76%) or the pure phosphoranimine monomer (40%) through variations in reaction conditions (25). These reactions use milder conditions than previously reported methods, with higher yields. In addition, the major side product, (CH 3 ) 3 SiCl, can be recycled to form one of the starting materials, N(Si(CH 3 ) 3 ) 3 .N-Silylphosphoranimines with alkyl and aryl substituents can be synthesized by reaction of commercial starting materials such as PCl 3 , ((CH 3 ) 3 Si) 2 NH, and Grignard reagents by way of a three-step process, with typical yields of 60-70%. These precursors are also accessible via a "one-pot" synthesis, which requires only isolation of the final product with yields of about 75% (3).Uses. Some of the most useful polyphosphazene derivatives are fluoroalkoxy derivatives, and amorphous copolymers are very useful as flame-retardant, hydrocarbon-solvent, and oil-resistant elastomers and have found aerospace and automotive applications. Polymers such as the amorphous comb polymer poly[bis(methoxyethoxyethoxy)phosphazene] (8) are of considerable interest as components of polymeric electrolytes in battery technology (1). Vol. 3 INORGANIC POLYMERS 35Polyphosphazenes are also of interest as biomedical materials and bioinert, bioactive, membrane-forming, and bioerodable materials (1).
