Na+-selective ChemFETs based on a novel ionophore: bis(phenylbenzo)-13-azocrown-5. Pijanowska, D. G., Luboch, E., Biernat, J. F., Dawgul, M., & Torbicz, W. Sensors and Actuators B-Chemical, 58(1-3):384--388, 1999.
Na+-selective ChemFETs based on a novel ionophore: bis(phenylbenzo)-13-azocrown-5 [link]Paper  doi  abstract   bibtex   
This paper presents performances of ChemFETs based on a novel sodium ionophore bis(phenylbenzo)-13-azocrown-5. The main feature of the ionophore is its increased lipophilicity. This study shows that ChemFETs based on the novel ionophore exhibit a relatively high selectivity coefficient for sodium over lithium ions K(Na+ /Li+)(pot), and that it is elevated for ChemFETs with PVC membrane containing o-nitrophenyl octyl ether (oNPOE) as a plasticizer. Moreover, a significant difference in selectivity coefficients for Na+ over Ca2+ ions, also depending on a plasticizer, was observed. In addition, procedure of synthesis of the ionophore is also described. A good stability of the output signal was obtained for Na+-ChemFETs based on Siloprene membrane. (C) 1999 Elsevier Science S.A.
