Single Molecule Luminescence of Lanthanide Double and Multi-Decker Complexes (C01)

• Subject Area: Experimental Condensed Matter Physics ; Inorganic Molecular Chemistry - Synthesis and Characterisation ; Physical Chemistry of Molecules, Liquids and Interfaces, Biophysical Chemistry
• Term: since 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 471424360

The aim of the project is (i) the synthesis of neutral and ionic multi-decker lanthanide complexes based on cy-clooctatetraene (COT) ligands and other organic macrocycles, (ii) the exploration of their optical properties in multiple environments from condensed to gas-phase, and (iii) the establishment of single photon sources using complexes immobilized on surfaces. Although there has been a recent renaissance in the chemistry of sand-wich and multi-decker complexes of the 4f elements, investigations of the optical properties of these species are still limited to a few ligand systems. We aim at a comprehensive investigation of the optical properties of a promising new range of COT-based 4f complexes in solid state, in solution, in gas phase and on surfaces.
