Abstract
Mono- and bis-benzo-15-crown-5-ether derivatives have been synthesized and determined
their potentiometric K+ selectivity factors. Of bis-crown ether urethanes highly selective Iigands
were found some of which was used as active ingredient in potassium selective membrane
electrode.
Sugar based crown ethers, aza-crowns and cryptands were also prepared and applied as
chiral catalyst in enantioselective reactions
