H-NMR of the uncomplexed calix[4]arene 5 shows it to exhibit a bowl conformation in solution. However the bridging methylenes are broadened indicating dynamic behavior. As a result it is likely that recrystallization fix)m solution produces a crystal phase which exhibits a bowl conformation. When heated the virgin crystals melt to give a fluid phase which is birefringent when viewed with a polar-... [Pg.393]
