Application of 37366-09-9, Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer, molecular formula is C12H12Cl4Ru2. In a patent, introducing its new discovery.
Synthesis and characterization of tris(heteroleptic) Ru(II) complexes bearing styryl subunits
We have developed and optimized a well-controlled and refined methodology for the synthesis of substituted pi-conjugated 4,4?-styryl-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 analytically pure compounds in high overall yields (>50% after 5 steps) and were isolated without significant purification effort. In these tris(heteroleptic) molecules, 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 analytical characterization and the associated methodology is described in detail. Preliminary photoluminescence and photochemical characterization of 1 and 2 strongly suggests that both molecules are energetically and kinetically suitable to serve as sensitizers in energy-relevant applications.
