Leveraging ligand conjugation to improve luminescence thermometry in Dy-single-molecule magnets

Abstract

Extended ligand conjugation enhances luminescent thermometry in [Dy₂(diketone)₆(bipyrimidine)] SMMs, as substantiated by crystallographic, photoluminescence, and lifetime decay analyses. This conjugation facilitates rare direct energy transfer from the ligands' singlet state to the metal centers, as evidenced by the nanosecond excited-state lifetime of Dy(III).
