RedlNear-infrared Boron-Dipyrromethene Dyes as Strongly Emitting Fluorophores

摘要

We present an overview of the state of the art in long-wavelength boron–dipyrromethene (BODIPY)fluorophores, focusing on strategies to shift the absorption and emission bands into the red/near-infrared (NIR) range of the spectrum. This report also discusses chemical modifications of thechromophoric core to obtain analyte-responsive fluorophores, including examples of pH and metalion indicators. Finally, we present a new series of phenanthrene-fused BODIPY dyes, emitting withhigh efficiency in the red/NIR region of the spectrum, as well as discussing potential applicationsthereof as probes.
