Beschreibungen/Notizen

• A probe for recognition of IIB (Zn 2+ , Cd 2+ , and Hg 2+ ) and VIB (Cr 3+ ) was developed based on the framework of BODIPY. The probe was synthesized by attaching DPA to 4-position of BODIPY. It exhibited excellent sensitivity and selectivity function for the IIB and VIB metal ions with 1:1 stoichiometry in acetonitrile solution. The limit of detection of Zn 2+ , Cd 2+ , Hg 2+ , and Cr 3+ were obtained by fluorescence "turn-on" and ranged from 20.6 to 23.1 nM. Other metal cations did not interfere with the emission sensing of Zn 2+ , Cd 2+ , Hg 2+ , and Cr 3+ . The underlying mechanism of fluorescence "turn-on" is based on the intramolecular PET, which controlled the fluorescence "on" or "off."
