Abstract / Full Text

Eight bifluorophoric (BF) molecules on the basis of paratherphenyl, stilbene, phenyl, biphenyl (donors) and coumarin 120 and phenylphtalimide (acceptors) connected by the bridging -CH2- were experimentally studied. It is shown that the absorption spectra of the BF are virtually additive to donor and acceptor fragments. The acceptor band alone is present in the fluorescence spectrum, which points to a complete nonradiative transfer of the electronic excitation energy. The spectra of induced BF emisson under flash-lamp and laser excitations are also examined.
