Synthesis And Properties Of Red Fluorescent Probe For Fe3+ Based On Boron-Dipyrromethene Dimer

A red fluorescence boron-dipyrromethene (BODIPY, BODIPY core=4,4-difluoro-4-bora-3a,4a-diaza-s-indacene) dimer 1, which is linked through beta-beta (2/6) position from a coupling reaction, exhibits efficient energy transfer with 222 nm pseudo Stokes' shift. The BODIPY dimer 1 shows high selectivity and sensitivity towards Fe (III) when the ion co-exsists with common interfering metal ions and it may be used as an indicator for Fe3+
