“…Whereas thymine and adenine display only a very weak fluorescence at room temperature (a,, -lo-') (13), 7-methoxycoumarin does emit under these conditions (14). Fluorescence emission spectra of CouO-C3-Ade ( I ) , CouO-C5-Ade (2), CouO-C,-Thy (3), and CouO-CH3 (4) were recorded in water and in methanol.…”

This paper is (ledicated to Profe.ssor Paul de Mayo or1 tile occasion of his 60th birrhdcryG R A~Y N A WENSKA and STEFAN PASZYC. Can. J. Chem. 62, 2006Chem. 62, (1984. Bichromophoric compounds containing a nucleotide base and coumarin linked with a polymethylene chain have been synthesized. A hypochromic effect was observed for adenine-coumarin pairs in contrast to the thymine containing compound. The fluorescence intensity of coumarin when bound into these systems was found to be significantly reduced. It has also been demonstrated that excitation energy is transferred from adenine or thymine to the coumarin moiety. Intermolecular dimerization of coumarin residues was observed upon irradiation of an adenine-coumarin pair. On a synthCtisC des composCs ii deux chromophores contenant un nuclkotide et une coumarine relies par une chaine polymethylene. Par opposition a ce qui est observe avec le composC semblable contenant de la thymine, on a observe un effet hypsochrome avec les paires adenine-coumarine. On a observe que I'intensitC de la fluorescence de la coumarine liCe a ces systemes est considCrablement rCduite. On a aussi demontrt qbe l'energie d'excitation est transfer6 de I'adCnine ou de la thymine vers la portion coumarine. Lors de I'irradiation d'une paire adenine-coumarine, on a observe une dimkrisation intermolCculaire des rksidus de la coumarine.[Traduit par le journal]

“…[18][19][20] The previously published structures for the salt 1 + (CF 3 SO 3 ) À , 16,17 and the two different solvates presented in the present work, 1 + (CF 3 SO 3 ) À Á(THF) 0.5 and 1 + (CF 3 SO 3 ) À Á(DCM), display a strong hydrogen bond between the coordinated water molecule on the cation and the triflate oxygen atoms. Since the evidence of the effect of the hydrogen bonding over the fluorescence of a molecule is previously known, [21][22][23] we analyze then in this manuscript the solvent effect over the photophysical properties of the 1 + cation in terms of solvent polarity and ability to form hydrogen bonds.…”
