    • Bis-calixarenes are prepared by the oxidative coupling of monophenolic precursors. Due to the lack of substituents ortho- to the biaryl linkage, these hosts are conformationally flexible. Crystal structures exhibiting biaryl torsion angles of 35° and 0° have been reported: (a) P. Neri, A. Bottino, F. Cunsolo, M. Piattelli, E. Gavuzzo, Angew. Chem. Int. Ed. 1998, 37, 166. doi:10.1002/(SICI)1521-3773(19980202)37:1/2<166::AID-ANIE166> 3.0.CO;2-P

    • These energy minimizations were carried out as follows: A model of dimer 8 was constructed from X-ray coordinates of the tetrabromocavitand bowl 1 and feet were removed. Energy minimizations were performed from an initial conformation with a ca. 90° biaryl. Calculations were performed using MacSpartan 1.0.4 (Wavefunction Inc.: Irvine, CA).
