The potentiometric response characteristics of the PVC membrane electrode based on the Mn(Ⅲ) complexes of the three new 'tailed' porphyrins toward SCN- have been studied.展开更多
A new ligand 25, 26, 27, 28-tetrakis[2-(o-methoxyphenoxy)ethoxy]calix[4]arene 3 was synthesized by direct base-strength-driven O-alkylation of calix[4]arene 1. 3 has been used as ionophore for cesium selective PVC mem...A new ligand 25, 26, 27, 28-tetrakis[2-(o-methoxyphenoxy)ethoxy]calix[4]arene 3 was synthesized by direct base-strength-driven O-alkylation of calix[4]arene 1. 3 has been used as ionophore for cesium selective PVC membrane electrode. The extraction for cesium and sodium with 3 have been also studied.展开更多
