Lanthanide chemistry has received renewed interest due to the special properties of these metals, which can primarily be attributed to their open f-shells. Indeed, lanthanide complexes are now seen as MRI contrast agents and as building blocks for nanomaterials. Gas-phase ultraviolet photoelectron spectroscopy is the best method for elucidating electron structure of metal complexes; however, there are few reports of the photoelectron spectra lanthanide complexes. We wish to understand the differences that lanthanide center has on electronic structure properties and what effect molecular structure has on electronic structure. Here we present the photoelectron spectra of a series of lanthanide complexes with 2,4-pentanedione (acac) and its fluorinated derivatives.
