Ligand Design with [CNSbF <sub>5</sub> ] <sup>−</sup> : An Ultrastrong π-Accepting Ancillary Ligand for Blue-Shifted MLCT Emission in Re(I) Complexes
fragment also stabilizes the diimine-based LUMO, partly attenuating the extent of the blue shift and illustrating the balance between π-backbonding and inductive effects. These isocyanoantimonate ligands thus provide a versatile anionic platform for transforming cationic MLCT emitters into charge-neutral phosphors while retaining high emission energies and quantum efficiencies, and for fine-tuning redox potentials and excited-state energies. The present findings offer a clear experimental support for the rational design of new phosphorescent materials, photosensitizers, and photocatalysts based on strongly π-accepting ancillary ligands.
