✦ Synopsis
Nvw nicino-and his-benzocrown ethers (5-28 and 29-48) with ciiffccrcnt substitucnts iind connccting chains wcrc prepared with thc aini to dcvclop novel alkali cation-rransport mediators fur hinlogic;il systems. The alkali cation sclectivitics of thc titlc coiiipounds wcrt' dctcrrnined in ion-sclective membrane elcctrodcs. Kcmarkable potiissiurn selectivity was observed with scvcral his-(knzo-1 ~-L.mwn-jjurerhanes.
'H-NMR data of some representative derivatives are summarized in Table 6.
