Abstract

Eleven lipophilic bis (monoaza croyn ether) derivatives [l and 2 (n= 0-3) and 3 (n= 1-3)] were synthesized, in which two monoaza crown ethers with 9-, 12-, 15-, or 18-membered rings are linked through the nitrogen atoms by an alkane-, diether-, or diester-type bridge chain bearing a dodecyl group. Sodium and potassium binding with the bis (monoaza crown ether) was determined potentiometrically and compared with those for previous bis (crown ...
