A new solid-contact Ag + -selective electrode was prepared with 9,10,12,13,24,25-hexahydro-5H,15H,23H-dibenzo[b,q][1,7,10,13,19,4,16]-entathiadiazacyclodocosine-6,16(7H,17H)-dione as ionophore, and α,ω-dihexylsexithiophene (DH-6T) ion-to-electron transducer. The sensor exhibited a working concentration range of 10 −8 to 10 −3 mol/L, with a near-Nernstian slope of 55.1±0.2mV/dec...
Four 20-membered N 2 S 4 -monoazathiacrown ethers have been synthesized and explored as neutral ionophores for Ag + -selective electrodes. Potentiometric responses reveal that the flexibility of the ligands has great effect on the selectivity and sensitivity to Ag + ions. The electrode based on ionophore 9,10,20,25-tetrahydro-5H,12H-tribenzo[b,n,r][1,7,10,16,4,13]tetrathiadiaza...
