The authors have developed and optimized a well-controlled and refined methodol. for the synthesis of substituted π-conjugated 4,4′-distyryl-2,2′-bipyridine ligands and also adapted the tris(heteroleptic) synthetic approach developed by Mann and co-workers to produce two new representative Ru(II)-based complexes bearing the metal oxide surface-anchoring precursor 4,4′-bis[E-(p-methylcarboxy-styryl)]-2,2′-bipyridine. The two targeted Ru(II) complexes, (4,4′-dimethyl-2,2′-bipyridine)(4,4′-di-tert-butyl-2,2′-bipyridine)(4,4′-bis[E-(p-methylcarboxy-styryl)]-2,2′-bipyridine) ruthenium(II) hexafluorophosphate, [Ru(dmbpy)(dtbbpy)(p-COOMe-styryl-bpy)](PF6)2 (1) and (4,4′-dimethyl-2,2′-bipyridine)(4,4′-dinonyl-2,2′-bipyridine)(4,4′-bis[E-(p-methylcarboxy-styryl)]-2,2′-bipyridine) ruthenium(II) hexafluorophosphate, [Ru(dmbpy)(dnbpy)(p-COOMe-styryl-bpy)](PF6)2 (2) were obtained as anal. pure compounds in high overall yields (>50% after 5 steps) and were isolated without significant purification effort. In these tris(heteroleptic) mols., NMR-based structural characterization became nontrivial as the coordinated ligand sets each sense profoundly distinct magnetic environments greatly complicating traditional 1D spectra. However, rational two-dimensional approaches based on both homo- and heteronuclear couplings were readily applied to these structures producing quite definitive anal. characterization and the associated methodol. is described. Preliminary photoluminescence and photochem. characterization of 1 and 2 strongly suggests that both mols. are energetically and kinetically suitable to serve as sensitizers in energy-relevant applications. In the part of experimental materials, we found many familiar compounds, such as 4,4′-Bis(chloromethyl)-2,2′-bipyridine(cas: 138219-98-4COA of Formula: C12H10Cl2N2)
4,4′-Bis(chloromethyl)-2,2′-bipyridine(cas: 138219-98-4) belongs to pyridine derivatives. Several pyridine derivatives play important roles in biological systems. While its biosynthesis is not fully understood, nicotinic acid (vitamin B3) occurs in some bacteria, fungi, and mammals. COA of Formula: C12H10Cl2N2
