We report the synthesis, magnetic and photoluminescence investigations of two bifunctional dysprosium complexes based on tridentate Schiff base ligands. Magnetic investigations reveal a genuine Single-Molecule Magnet (SMM) behavior with out-of-phase signals up to 60 K, and the tunable emission arising from the Schiff base ligands.
