| Zusammenfassung: | A graphene oxide- (GO-) boradiazaindacenes (BODIPY) charge-transfer complex
(BGO)
has been easily synthesized, and the structure of
BGO
was confirmed by FT-IR and atomic force microscopy (AFM). Moreover, the
BGO
was found that could be used as a turn-on fluorescent sensor for Hg
2+
. Upon addition of Hg
2+
, the fluorescence of
BGO
would be enhanced since the energy transfer between BODIPY and GO was inhibited. The selectivity and the competition performance of
BGO
towards Hg
2+
were good among other heavy metal ions. |
