Triheterometallic lanthanide complexes made from kinetically inert lanthanide building blocks
- Abstract:
- Three molecular structures, each containing three different lanthanide(III) centres, were made by coupling three kinetically inert lanthanide(III) complexes in an Ugi reaction. These 2 kDa molecules were purified by dialysis, and characterised using NMR and luminescence. The photophysical properties of these heterotrimetallic complexes were investigated and are discussed by comparison with simpler, but related, heterobimetallic compounds. It was found that an amino-naphthalene unit inhibits sensitisation of terbium, while the spatial arrangement of the chromophores and lanthanide(III) centres in these molecules inhibited efficient sensitisation of europium. We conclude that the intramolecular collisions required for efficient Dexter energy transfer from the sensitizer to the lanthanide(III) centre can be prevented by steric congestion.
