A class of wavelength-tunable near-infrared aza-BODIPY dyes and their application for sensing mercury ion
چکیده انگلیسی


• A new series of NIR aza-BODIPY derivatives was successfully designed and synthesized.
• These aza-BODIPY derivatives exhibited tunable absorption and emission bands over a wide range by introducing different aromatic substitutes.
• Excellent NIR probes for Hg2+ based on aza-BODIPY derivatives have been realized.

We present the design, synthesis, photophysical properties and application for sensing mercury ion, of a series of excellent near infrared fluorescent aza-boron-dipyrromethene (aza-BODIPY) dyes. The introduction of different aromatic substituents to the aza-BODIPY core induced red-shifted absorption and emission wavelengths due to the extension of the π-system. In addition, “turn-off” fluorescence responses and solution color changes selectively toward mercury ion have also been realized. The Hg2+-induced fluorescence quenching may be assigned to the energy or electron transfer from emissive aza-BODIPY core to Hg2+.

A new class of NIR aza-BODIPY fluorescent dyes with tunable emission wavelength has been used as excellent “turn-off” type fluorescent probes for Hg2+.Figure optionsDownload as PowerPoint slide
