Fundamentals of Photoluminescent Lanthanide-Antenna Complexes (C03)

• Subject Area: 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 project addresses the fundamental properties of photoluminescent lanthanide-antenna complexes containing one, typically trivalent, metal center. It aims to generate in-depth understanding of the interplay between electronic structure and non-radiative deactivation of the metal centers by multiphonon relaxation (MR) – due to ligands and solvent molecules. For this condensed phase properties will for the first time be compared with the associated MR-related phenomena of gas-phase complexes. We focus in particular on near-IR (nIR) emitting systems where MR effects are typically strongest. In addition to advancing the description of non-radiative deactivation in discrete metal luminophores, this will also allow for the systematic development of improved nIR luminophores.
