Pyridyldiimine macrocyclic ligands: Influences of template ion, linker length and imine substitution on ligand synthesis, structure and redox properties

Syntheses are reported for a series of 2,6-diiminopyridine-derived macrocyclic ligands with flexible alkyl linkers, formed via templated Schiff base condensations around alkaline earth metal triflate salts.

Syntheses are reported for a series of 2,6-diiminopyridine-derived macrocyclic ligands with flexible alkyl linkers, formed via templated Schiff base condensations around alkaline earth metal triflate salts. Systematic comparisons of the physical and electronic properties of the complexes were conducted using NMR spectroscopy, mass spectrometry, solution-phase UV–Vis spectroscopy, cyclic voltammetry and single-crystal X-ray crystallography.
