Long Range Electron Transfer Quenching in Polyamine Chains Bearing a Terminal N...
Pina, Fernando; Lima, J. C.; Lodeiro, Carlos; Melo, J. Seixas de; Díaz, Pilar; Teresa Albelda, M.; García-España, EnriqueThe fluorescence emission of a naphthalene unit attached to a polyamine chain is quenched by intramolecular electron transfer from the deprotonated amines to the excited fluorophore. Measurements of the respective quenching rate constants as a function of the distance, reveal an exponential dependence with β = 0.45 Å-1. Identical measurements carried out in deuterated water have shown a similar dependence with ...
