Abstract

original image

Competition with a monovalent cyclodextrin host (blue cones) in solution drives the multivalent binding of a Eu3+ complex and a sensitizer molecule to cyclodextrin monolayers through a nonlinear self-assembly process. Adamantyl groups (light-blue spheres) are attached to the EDTA ligand (black) and the antenna molecule (orange), which has a carboxylate group for coordination to the Eu3+ ion (yellow or red in free or complexed form, respectively).
