Synthesis, characterization and photoluminescence of substituted terpyridine compounds and their molecular docking studies with bovine hemoglobin

Six compounds p-hydroxyl-4′-phenyl-terpyridine (L1), m-hydroxyl-4′-phenyl-Terpyridine (L2) o-hydroxyl-4′-phenyl-terpyridine (L3) [Zn(Cl)2L1] (1), [Zn(Cl)2L2] (2) and [Zn(Cl)2L3] (3) have been synthesized and characterized by IR, 1H NMR, elemental analysis and single crystal X-ray diffraction, along with their photoluminescent properties. The bindings of the compounds with bovine hemoglobin (BHb) were also studied.
