Nagano, Koichi published the artcileSynthesis of functional heteroaromatic compounds. Synthesis of viologen derivatives. I, Name: 1,1′-Diphenyl-[4,4′-bipyridine]-1,1′-diium chloride, the publication is Aromatikkusu (1988), 40(5/6), 144-9, database is CAplus.
Viologens I (R = Me, halogen) were prepared by the reaction of N,N‘-bis(2,4-dinitrophenyl)-4,4’-bipyridinium salts with substituted anilines. The polarog. behavior of I at a dropping Hg electrode was studied in H2O. I embedded in PVP matrix indicated rapid reversible photoreductions The effect of the substituents on the photochromic behavior of I was also discussed.
Aromatikkusu published new progress about 47369-00-6. 47369-00-6 belongs to pyridine-derivatives, auxiliary class Pyridine,Salt,Benzene,Organic ligands for MOF materials,Nitrogen containing MOF ligands,Nitrogen containing MOF ligands, name is 1,1′-Diphenyl-[4,4′-bipyridine]-1,1′-diium chloride, and the molecular formula is C22H18Cl2N2, Name: 1,1′-Diphenyl-[4,4′-bipyridine]-1,1′-diium chloride.
