AbstractA series of sterically and electronically modulated phenyl‐bridged α‐diimine ligands L1–L6 of the general formula Ar‐N=C(Me)‐C(Me)=N‐C6H4‐N=C(Me)‐C(Me)=N‐Ar have been synthesized (L1 : Ar = 2,6‐iPr2‐C6H3; L2: Ar = 2,6‐Me2‐C6H3; L3: 4‐Me‐C6H4; L4: Ar = 4‐Et‐C6H4; L5: Ar = 2,4,6‐Cl3‐C6H2; L6: Ar = 4‐Cl‐C6H4). All of which have been characterized by 1H NMR, 13C NMR, IR, and elemental analysis. In addition, the effect of the electronic modification was studied by UV–Vis spectroscopy, and the structure of a representative ligand was confirmed by single‐crystal X‐ray diffraction. Moreover, a DFT electronic structure of the same ligand has been determined.
