A BODIPY-based colorimetric and fluorescent chemosensor 1 anchored with dipyridylamino (DPA) receptor has been designed, synthesized and characterized. It exhibited a simultaneous sensitive recognition for Cu2+, Hg2+ and Pb2+ ions. With the addition of these three kinds of metal ions into 1 in CH3CN, its initial absorption maximum displayed obvious blue shifts, and the color changes of the solution...
A novel near-infrared fluorescent chemosensor based on BODIPY (Py-1) has been synthesized and characterized. Py-1 displays high selectivity and sensitivity for sensing Cu 2+ over other metal ions in acetonitrile. Upon addition of Cu 2+ ions, the maximum absorption band of Py-1 in CH 3 CN displays a red shift from 603 to 608nm, which results in a visual color change from pink...
