On May 27, 2005, Toele, P.; Glasbeek, M. published an article.Electric Literature of 75449-26-2 The title of the article was Ultrafast excited-state intramolecular double proton transfer dynamics of [2,2′-bipyridyl]-3,3′-diamine. And the article contained the following:

A femtosecond fluorescence upconversion study of [2,2′-bipyridyl]-3,3′-diamine (BP(NH2)2), in liquid solution, is reported. It is concluded that photoexcited BP(NH2)2 undergoes a branched intramol. double proton transfer reaction comprising two trajectories: (a) ultrafast double proton transfer (<100 fs) followed by twisting (∼250 fs); (b) a combined process of double proton transfer and twisting, with an overall reaction time of ∼250 fs. Picosecond transient fluorescence is attributed to vibrational cooling in the excited product state. The lifetime of ∼10 ps of the tautomer product state is indicative of conical intersection of the product- and ground-state potential energy surfaces. The experimental process involved the reaction of [2,2'-Bipyridine]-3,3'-diamine(cas: 75449-26-2).Electric Literature of 75449-26-2
