  • Title: Synthesis of symmetrical multichromophoric Bodipy dyes and their facile transformation into energy transfer cassettes.
    Author: Bozdemir OA, Cakmak Y, Sozmen F, Ozdemir T, Siemiarczuk A, Akkaya EU.
    Journal: Chemistry; 2010 Jun 01; 16(21):6346-51. PubMed ID: 20401877.
    Abstract:
    Multichromophoric 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-resolved 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.
