Abstract
The C-3-symmetrically lower-rim capped p-tert-butylcalix[6]arene 6 has been synthesized and its solid-state structure has been determined by X-ray dif fraction analysis. The triethanolamine-derived triple bridge fixes the cali xarene part in the cone conformation. Mass spectrometry studies (MALDI-TOF) indicate that host-guest interaction of 6 with alkali metal ions decreases in the order Cs >K much greater than Na, Li. (C) 2001 Elsevier Science Ltd .
