Abstract
New 1,3-alternate calix[4]arenecrown-6 and calix[4]arene-crown-5, whic h are selective for caesium and potassium ions respectively, have been synthesized and linked covalently to silica gel via hydrosilanization and successfully employed for the chromatographic separation of Cs+ a nd K+ from alkali metal ions.
