Abstract

Abstract A series of cyclen (1, 4, 7, 10-tetraazacyclododecane) derived molecular receptors for aromatic oxoanions, that are activated by complexation with Cd (II), have been covalently linked to 3-(glycidoxy) propyl-functionalised silica gel (70–230 mesh). These immobilised receptor complexes are highly effective for the sequestration of o-hydroxybenzoates and 2- naphthoate from aqueous solution, achieving a> 80% saturation level by stirring the ...
