A further category of cavitands are the calixarenes (Gutsche, Dhawan, No Muthukrishnan, 1981 Gutsche Levine, 1982). Structure (255) illustrates an example of this type which is readily prepared by treatment of 4-f-butylphenol with formaldehyde and base. The compound may exist in other conformations besides the saucer-shaped one illustrated by (255). Similarly, f-butyl-calix[4]arene (256 R = CH2COOH) has an enforced hydrophilic cavity in the shape of a cone the alkali and ammonium salts of this host are soluble in water (Arduini, Pochini, Reverberi Ungaro, 1984).
