“…Previous studies22 concerning the evaluation of the properties as selective anion sensors of polymeric organotin carboxylates indicated that in the first 70 h of application the response of membranes containing this type of organometallic moieties decreased with time, a fact attributed to lack of reversibility in the formation of the anion–sensor complex. To exclude the hydrolysis of tin carboxylate as a possible cause for the loss of response, we have tested TBTSE‐E and poly(TBTSE) under the same conditions as for the electrochemical chloride determinations 22. Thus, both the products have been stirred at room temperature, as well as at 100 °C, in a 0.01 M KCl solution.…”

Novel polymeric derivatives bearing tributyltin carboxylate moieties in the side chain were synthesized. The coordination at tin in solution and in the solid state was investigated by both Sn-NMR and FT-IR: the metal atom appears completely tetracoordinated in chloroform solution, while in the solid state all polymeric products exhibit both tetra-and pentacoordination at tin, the latter increasing with the amount of tin containing units. No evidence of tin leaching by hydrolysis of the organometallic ester was observed for these materials.

“…This behaviour, well established for analogue non-polymeric compounds bearing the triphenyltin carboxylate moiety, is uncommon for tributyltin derivatives. These last compounds are in fact usually pentacoordinated [28,29], at least when not hindered by the presence of a macromolecular backbone, as demonstrated by X-ray crystallography [30].…”

“…Evidence against hydrolysis of Sn from the polymers is provided by the fact that no hydrolysis at all is observed in similar polymeric triorgano[(1-oxoalkyl)oxy]stannanes even after stirring in an aqueous 0.1m KCl suspension at room temperature for two weeks, as checked by FT-IR spectroscopy [31]. In addition, it is postulated that grafting the triorgano[(1-oxoalkyl)oxy]stannane to the polymeric support should introduce some steric demand, hampering the facile and reversible coordination of the ionic ligand to the Sn-center.…”

Polystyrene copolymers of the type (PÀH) 1Àx (PÀ(CH 2 ) n ÀCOOSnR 3 ) x containing [(1-oxoalkyl)oxy]triphenylstannane or tributyl[(1-oxoalkyl)oxy]stannanes as side chains (PÀH styrene; PÀ(CH 2 ) n ÀCOOSnR 3 para-substituted styrene-like monomeric unit with RPh (x 0.1), Bu (x 0.5); n 2 ± 4) were investigated. The tributyl[(1-oxoalkyl)oxy]stannane copolymer was prepared by direct conversion of the corresponding copolymeric methyl esters with hexabutyldistannoxane. By contrast, the [(1-oxoalkyl)oxy]triphenylstannane copolymer could be prepared only by a procedure involving two reaction steps consisting of a preliminary hydrolysis of the related methyl ester (PÀH) 1-x (PÀ(CH 2 ) n ÀCOOMe) x followed by functionalization of the corresponding poly(carboxylic acid) (PÀH) 1-x (PÀ(CH 2n ÀCOOH) x with hydroxytriphenylstannane. Attempts to directly convert the methyl ester with hydroxytriphenylstannane or hexaphenyldistannoxane led to the formation of uncompletely functionalized product. The structure of the stannane-functionalized polymers was investigated in solution and solid state by NMR, IR, and thermal analysis. The tributylstannane and triphenylstannane copolymers were assessed as chloride-selective anion carriers in polymeric-liquid-membrane potentiometric ion-selective electrodes.
