Lanthanide tris complexes with unsubstituted and diarylcyclopentadienyl ligands have been synthesized and studied by single crystal X-ray diffraction analysis and optical spectroscopy. It is shown that the ligand field formed by three Cp ligands can be an effective tool to decrease the energy of 4f5d configuration and as a result for Ce complexes the luminescence in red region and energy of 5d1 level as 470 nm were observed. The energy transfer scheme S → 4f5d → 4ff∗ realized in the designed complexes has been deciphered by the comparison of the spectroscopic data for Ce3+, Pr3+, Gd3+ and Tb3+ ions. The spectroscopic redshift of the first electric dipole-allowed 4f5d transition of the Ce3+ ion was interpreted by combining the centroid shift and the crystal-field splitting for organometallic compounds at the first time.
