Two propeller-shaped chiral Co III 3 Y III complexes built from fluorinated ligands are synthesized and characterized by single-crystal X-ray diffraction (SXRD), IR, UV-vis, circular dichroism (CD), elemental analysis, thermogravimetric analysis (TGA), electron spray ionization mass spectroscopy (ESI-MS), and NMR ( 1 H, 13 C, and 19 F). This work explores the sensing and discrimination abilities of these complexes, thus providing an innovative sensing method using a 19 F NMR chemosensory system and opening new directions in 3d/4f chemistry. Control experiments and theoretical studies shed light on the sensing mechanism, while the scope and limitations of this method are discussed and presented.
