| 摘 要： | Two novel 25,27-dihydroxy-26,28-bis(3-phenylthiapropxy)-calix4]arene(3) and 25,27-dihydroxy-26,28-bis(3-phenylthiapropoxy)-5,11,17,23-tetra-tert-butylcalix4] arene (4) were synthesized for the evaluation of their ion-selectivity in ion-selective electrodes(ISEs).ISEs based on 3 and 4 as neutral ionophores were prepared,and their selectivity coefficients for Ag^ (lg KAg,M^pot)were investigated against other alkali metal,alkaline-earth metal,aluminum,thallium(Ⅰ）,Lead and some transition metal ions using the separate solution method (SSM).These ISEs showed excellent Ag^ seletivity over most of the interfering cations examined,except for Hg^2 and Fe^2 having relative smaller interference(lg KAg,M^pot≤-2.1).

| Abstract: | Two novel 25,27‐dihydroxy‐26,28‐bis(3‐phenyilhiapropoxy)‐calix4]arene (3) and 25,27‐dihydroxy‐26,28‐bis(3‐phenylthiapropoxy)‐5,11, 17, 23‐tetra‐tert‐butylcalix4]arene (4) were synthesized for the evaluation of their ion‐selectivity in ion‐selective electrodes (ISEs). ISEs based on 3 and 4 as neutral ionophores were prepared, and their selectivity coefficients for Ag+ (lg Apotag,M) were investigated against other alkali metal, alkaline‐earth metal, aluminum, thallium (I), lead and some transition metal ions using the separate solution method (SSM). These ISEs showed excellent Ag+ selectivity over most of the interfering cations examined, except for Hg2+ and Fe2+ having relative smaller interference (Ig Kpotag,M≤ ? 2.1). |
