Abstract :
The C3-symmetrically lower-rim capped p-tert-butylcalix[6]arene 6 has been synthesized and its solid-state structure has been determined by X-ray diffraction analysis. The triethanolamine-derived triple bridge fixes the calixarene 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⪢Na, Li.
