“…Nitrate-selective electrodes [1], humidity sensors [2], fluoride electrodes [3], and devices for detection of metal ions [4,5] based on ICP have been described. Polypyrrole (PPy) has attracted most attention because it is one of the most stable ICP known [6] and one of the easiest to synthesize, and so has tremendous technological potential.…”

Cobaltabis(dicarbollide) [3,3'-Co(1,2-C2B9H11)](-)-doped polypyrrole (PPy) films have been prepared galvanostatically on glassy carbon electrodes in acetonitrile solution. The potential response behavior of the film of this new material has been investigated in some common pH buffers and in acid-base titrations. The potentiometric characteristics of the resulting films are indicative of a quasi-Nernstian response (approximately 50 mV/pH unit), a linearity range from pH 12 to 3 and correlation coefficients (r2) of approximately 0.98. The electrode is suitable for pH measurements and for monoprotic titrations of strong alkalis with strong acids, and weak bases with strong acids, but the long response time hinders the use of this electrode for multiprotic titrations. The time response has been dramatically improved by reducing the film thickness by using the template effect of a non-conducting polymer (PVC) cast over the graphite surface before PPy deposition. PPy polymerization occurs in the free channels of PVC leading to the formation of PPy wires. The morphological change of PPy does not affect the slope or linearity range. The response of the PVC-PPy electrochemical sensor is rapid and the sensor is easy to prepare, at low cost, and its performance is comparable with that of commercial glass electrodes.

The reaction of triflic anhydride activated carbonyl compounds with 5-phenylbarbituric acids in a mild, non-catalyzed one-step procedure yields unusual tricyclic pyrano[2,3-d]pyrimidines or oxazolo[3,2-c]pyrimidines containing an ADA hydrogen bond pattern. By subsequent functionalisation, other derivatives are accessible, including for instance a pyrimidine containing phenolphthalein analogue, thereby combining established chromophoric systems with a supramolecular recognition unit.

Abstract:The use of organic chemistry reactions to introduce additional functional groups on polyanilines is described. Among the reactions discussed are: electrophilic aromatic substitution, nucleophilic addition to the aromatic rings, nucleophilic substitution on the amine groups and reactions on pendant groups. The use of combinatorial chemistry techniques, by coupling of combinatorially synthesised diazonium salts with polyaniline, to produce a functionalized polyanilines library is also reviewed. The modification of polyaniline introduces or alters different properties of the materials: solubility, self-doping and redox coupled ion exchange. The tailoring of those properties to technical applications is therefore examined.
