The two isoelectronic bipyridyl derivatives [2,2′-bipyridyl]-3,3′-diamine (BP(NH2)2) and [2,2′-bipyridyl]-3,3′-diol (BP(OH)2) are exptl. known to undergo very different excited-state double proton transfer processes that result in fluorescence quantum yields that differ by four orders of magnitude. Such differences have been theor. explained in terms of topog. features in the potential energy surface and the likely presence of conical intersections. The hypothetical hybrid compound [2,2′-bipyridyl]-3-amin-3′-ol (BP(OH)(NH2)) presents intermediate photochem. features of its “ancestors”. In this report we analyze the photochem. properties of a whole family of “dark” (not fluorescent) states that can be accessed from each bipyridyl derivative upon irradiation of light of a given wavelength and their potential application as photomemory devices. In the light of our d. functional theory (DFT), time-dependent DFT (TDDFT), and complete active space SCF (CASSCF) calculations, BP(NH2)2 is the more likely candidate to become a photomemory device. The experimental process involved the reaction of [2,2′-Bipyridine]-3,3′-diamine(cas: 75449-26-2).Related Products of 75449-26-2
