Molecular Recognition

Objective:
To investigate the host-guest chemistry of the second coordination sphere of Fe-siderophores and related complexes as it relates to molecular recognition. Our approach includes characterization of new supramolecular assemblies and bulk liquid membrane transport studies.


Ionophore-Siderophore Supramolecular Assemblies

 

Ferrioxamine B / 18-crown-6
Ferrioxamine B / benzo-18-crown-6
Ferrioxamine B / dicyclohexyl-18-crown-6
