    A study about pH chemically modified electrodes based on amino-derivatives of naphthalene (1992)
    Springer
    Microchimica acta 107 (1992), S. 27-36

    Notes: Abstract The electrochemical polymerization of amino-derivatives of naphthalene has been studied on the platinum wire electrodes. The effects of acidity of the modifying media and the potential scan rate on the cyclic voltammograms are verified. As potentiometric pH sensors, the electrodes prepared from 1-naphthylamine and 2,3-diaminonaphthalene showed performance characteristics superior to some other electrodes tested. The electrode modified with 1-naphthylamine in the optimum medium showed a nearly Nernstian response of 4.20–13.70 pH and a slope of -54.8 mV/pH, while the linear range of the electrode prepared by 2,3-diaminonaphthalene was 4.00–13.60 pH, with a slope of -52.4mV/pH.

    Electropolymerization of 1-naphthylamine and the structure of the polymer film (1995)
    Springer
    Microchimica acta 117 (1995), S. 145-152 
    Details
    ISSN: 1436-5073
    Keywords: poly(1-naphthylamine) ; polymer film ; chemically modified electrode

    Topics: Chemistry and Pharmacology
    Notes: Abstract The electrochemical polymerization of 1-naphthylamine in acetonitrile solution was studied by cyclic voltammetry. Infrared spectroscopy, elemental analysis and quantum chemical calculation were used to investigate the polymer film formed. The results showed that in an acetonitrile solution containing sodium perchlorate and hydrochloric acid, the polymerization of 1-naphthylamine occurred at thep-position. A possible structure of poly(1-naphthylamine) is suggested.

    A perfume odour-sensing system using an array of piezoelectric crystal sensors with plasticized PVC coatings (1996)
    Springer
    Fresenius' Zeitschrift für analytische Chemie 355 (1996), S. 194-199

    Notes: Abstract Using PVC polymer as membrane matrix and di-n-octylphenyl phosphate (DOPP) as plasticizer, a piezoelectric crystal sensor (PCS) array with 12 adsorptive materials selected from 68 compounds by cluster analysis has been constructed as a perfume odour-sensing system. The frequency shift data obtained from the sensor array responding to four commercial perfume odours are first autoscaled and then treated by principal component analysis. The experimental results show that the plasticized PVC membrane PCS array provides improved performance of pattern recognition compared with the single adsorptive coating PCS array. The frequency shift response characteristics of these sensors have been investigated experimentally. The proposed sensor array has also been applied to the classification of commercial spirituous liquor, wine and soft drink samples, as well as aliphatic alcohol homologues and isomers.
