U.2016-02-082016-02-0820100947-6539http://hdl.handle.net/11693/22310Multichromophoric boron-dipyrromethene (Bodipy) dyes synthesized on phenylene-ethynylene platforms have been be converted to energy transfer cassettes in a one-step chemical transformation. Excitation energy transfer processes in these highly symmetrical derivatives were studied in detail, including time-re-solved fluorescence spectroscopy techniques. Excitation spectra and the emission lifetimes suggest efficient energy transfer between the donor and acceptor chromophore. These novel energy transfer cassettes, while highlighting a short-cut approach to similar energy transfer systems, could be useful as large pseudo-Stokes shift multichromophoric dyes with potential applications in diverse applications.EnglishDyes/pigmentsSonogashixa couplingChemical transformationsDipyrrometheneDiverse applicationsDonor and acceptorDyes/pigments energy transferEfficient energy transferEmission lifetimeEnergy-transfer systemsExcitation spectrumFluorescence spectroscopy techniquesPotential applicationsStokes shiftBoronBoron compoundsChromophoresFluorescence spectroscopyFluorophoresSynthesis (chemical)Energy transferArticle10.1002/chem.2009034491521-3765
