Novel Lanthanide(III) Complexes with Pyrrolidinofullerene Ligands: Synthesis and Characterization

Novel europium and samarium complexes with pyrrolidinofullerene-based ligands are synthesized. Their compositions and molecular structures are elucidated using elemental analysis, MALDI-TOF mass spectrometry, as well as FTIR and NMR spectroscopy. It is shown that the metal ion coordinates with one pyrrolidinofullerene molecule. The photoluminescence spectra of the resulting complexes are similar to those of the free fullerene ligand.
