Abstract

|
|
|
Calix[6]arene react with formaldehyde and secondary amines to yields water soluble Mannich bases which can be converted to the corresponding quaternary salts. Treatment of the quaternary salts with a nucleophile such as cyano, ethoxy, and hydride yields p-substituted calix[6]arenes. Calix[8]arene too react with formaldehyde and diallyl amine to yield a water soluble Mannich base. The transport of neutral arenes through an aqueous phase along a concentration gradient mediated by those of water soluble calixarenes as molecular carrier was studied in a U-type cell. Naphthalene, anthracene, pyrene, and fluoranthene are tested as a neutral solid guest compounds for the transport experiment.
