Four new acyclic dithia benzene derivatives have been synthesized: 1,3-bis[(ethylthio)methyl]benzene; 1,3-bis-[(pentylthio)methyl]benzene; 1,3-bis[(octylthio)methyl]benzene, 1,3-bis[(dodecylthio)methyl]benzene. All compounds have been tested as silver(I) ion sensors in membrane-based ion-selective electrodes, exhibiting good sensitivity, detection limits, reproducibility and selectivity. The chemical recognition of silver(I) by these receptors is compared to the behaviour presented by closely related macrocyclic and acyclic polythia compounds. © 1994.
