Keywords:Borondipyrromethene, fluorescence, absorption, quantum yields
AbstractA novel BODIPY derivative containing a 17 carbon alkyl chain at the 8th (meso) position of the BODIPY core has been synthesized by a previously reported method for making analogous compounds by way of a Knoevenagel-type condensation (Y. Tokoro, et al., Tetrahedron Lett. 2010, 26:3451, A. Nagi et al., J. Am. Chem. Soc. 2008, 130:15276). The compound shows a strong absorption at 520 nm and emits at 531 nm in CH2Cl2. Absorption and emission spectra in different solvents show little variation. The compound is highly fluorescent with a quantum yield of 0.82.
