Abstract

Fifteen new macrocyclic, macrobicyclic and macrotricyclic crown ether compounds with sym‐dibenzo‐16‐crown‐5 units have been prepared. The series includes macrocyclic polyether and bis(crown ether) compounds with proton‐ionizable carboxylic or phosphonic acid monoethyl ester groups and bis(crown ether) and macrotricyclic polyether compounds with two sym‐dibenzo‐16‐crown‐5 units linked by amide, diamide, or diester functions.
