Tuning luminescence of didysprosium single-molecule magnets with a π-conjugated/non-conjugated bridging ligand

Herein, we reported two didysprosium single-molecule magnets constructed with {Dy(bbpen)(MeOH)} subunits and a pi-conjugated tpb or non-conjugated tpcb bridging ligand. The former exhibits extremely weak luminescence that makes it difficult to simulate its emission spectra. However, the later shows obviously enhanced and well-resolved luminescence, which helps us to gain knowledge about the magneto-optical correlation and the relevant magnetic energy levels.

Automated summary

In this study, we presented two dysprosium single-molecule magnets with different bridging ligands, showing varying luminescence properties. While one displayed weak luminescence making simulation challenging, the other exhibited enhanced and well-resolved luminescence, providing valuable insights into magneto-optical correlation and magnetic energy levels.
