On December 3, 2010, Ortiz-Sanchez, Juan M.; Gelabert, Ricard; Moreno, Miquel; Lluch, Jose M. published an article.Quality Control of [2,2′-Bipyridine]-3,3′-diamine The title of the article was Modulating the Photochemistry of Bipyridylic Compounds by Symmetric Substitutions. And the article contained the following:
A quantum electronic study of the effect of substituents on (2,2′-bipyridyl)-3,3′-diol and (2,2′-bipyridyl)-3,3′-diamine is presented. A large difference in the photochem. behavior between the original and the substituted selected systems is expected. For the sake of simplicity, the study is restricted to the sym. bi-substituted compounds: fluorine, the more electroneg. atom and thus a strong σ-acceptor but also a weak π-donor group, and NO2, a strong π-acceptor substituent. Among the large set of compounds studied, two receive special attention: 5,5′-dinitro-(2,2′-bipyridyl)-3,3′-diamine and 6,6′-difluoro-(2,2′-bipyridyl)-3,3′-diol. While in the former case the nitro substitution transforms (2,2′-bipyridyl)-3,3′-diamine, previously suggested to behave as a photomemory material, into a simple fluorescent species, the latter substitution turns (2,2′-bipyridyl)-3,3′-diol into a fresh new candidate for a photomemory device. The experimental process involved the reaction of [2,2′-Bipyridine]-3,3′-diamine(cas: 75449-26-2).Quality Control of [2,2′-Bipyridine]-3,3′-diamine
