摘要：

Di-n-butyltin dihalides (Bu2SnY2, Y=Cl, I, OMe) behaved as neutral carriers for anion-selective electrodes. A variety of selectivity patterns have been obtained by using Bu2SnY2 which differ in the electronegative substituents Y on the Sn atom. However, all electrodes containing Bu2SnY2 provided the highest degree of selectivity for the SCN- ion. The interaction of Bu2SnY2 with the SCN- ion was studied in the organic solution by means of 13C NMR spectroscopy. In the case of the addition of NaSCN, a significant increase of the value of 1J(119Sn–13Ca) was observed in the 2.0 M CDCl3 solution of Bu2SnCl2.
