Three novel phenyltelluroalkoxyl functionalized tweezer-like calix[4]arenes 6–8 and two monophenyltelluropropoxyl functionalized calix[4]arenes 10 (cone conformer) and 12 (partial cone conformer) were synthesized and characterized. They are good Ag+-selective ionophores in ion-selective electrodes evaluated by electromotive force measurements of polymer membrane electrodes. The tweezer-like ionophores 6–8 showed excellent extraction ability towards Ag+ and Hg2+.
合成并表征了三种新型苯基碲烷氧基功能化的夹子状杯[4]芳烃化合物6至8以及两种单苯基碲丙氧基功能化的杯[4]芳烃化合物10(锥形构象)和12(部分锥形构象)。通过聚合物膜电极的电动势测量,它们在离子选择性电极中表现出良好的Ag+选择性离子载体。夹子状离子载体6至8对Ag+和Hg2+具有出色的萃取能力。
