Diazo coupling between calix[4]arene and five substituted benzenediazonium ions in tetrahydrofuran at 5°C in the presence of pyridine afforded the tetrasubstituted calix[4]arenes as main products and small amounts of mono-, di- and tri-substituted calix [4]arenes even in the presence of unchanged calix[4]arene: the unusual autoaccelerative substitution reaction is attributed to the specific hydrogen-bonding effect among the calix[4]arene OH groups. The products were applied as new 'chromophoric calix[4]arenes,' which selectively recognised Li+.
