Calixarene tubes as cation receptors |
| abstract |
A cyclic compound of formula (I)wherein Rx groups which may be the same or different are selected from -O-(CH2)n-O- where n is an integer of from 2-6; Ry and Rz groups which may be the same or different are independently selected from hydrogen, halogen or a hydrocarbyl group; Ra together with Rb of the adjacent phenyl ring and Rc together with Rd of the adjacent phenyl ring form a group of formula -(CH2)m- or -(CH2)p-O- where m and p are integers of from 1-5, and each group Ra-Rb and Rc-Rd may be the same or different; and x is an integer of 2 or more, such as 4. Compounds of formula (I) display particular selectivity for specific ions such as potassium ions. They are useful inter alia in reactions where scavenging of a specific cation is required or as ion specific electrodes. |
