Metallo-complexes with functionalised tripodal ligands as molecular recognition devices

 

project PN-II-RU-TE-2011-3-0252 (contract nr. 33/2011)

financed by

Design and synthesis of functionalized tripodal ligands derived from tris(2-aminoethyl)-amine and 2-formyl-6-hydroxymethyl-p-cresol with different functional groups (amino, carboxylato, -OH) or biological residues (amino-acids, urea or guanidinium).

Synthesis and structural characterization (by X-ray diffraction on single crystals) of mono- and binuclear complexes (homo- and heterobinuclear complexes) of the functionalised tripodal ligands with 3d metal ions and/or lanthanides(III).

 

Investigation of the luminescent and magnetic properties of the metallocomplexes.

Investigation of the ability of the metallocomplexes with tripodal coordination sites in molecular recognition of different chemical species (anions, cations, small biological molecules).

Synthesis and structural characterization of complexes containing two tripodal coordination sites.

 

Investigation of the ability of the metallocomplexes with one or two functionalized tripodal coordination sites in molecular recognition of different chemical species (anions, cations, small biological molecules).

 

Synthesis and structural characterization of molecular tweezers based on bicompartmental ligands, for specific recognition by hydrogen bonding of complexes with octahedral stereochemistry and two water or two ammonia ligands coordinated in trans positions.
