Özet:

 

Fluorescent sensors have attracted an important
interest due to their advantages such as high selectivity, rapid response, easy
to use etc.  In this study, a rhodamine based
fluorescent sensor, RhDP, was synthesized, and used for selective detection of Cd2+
ions. The sensor responds to Cd2+ via the coordination induced
fluorescence activation (CIFA) mechanism. RhDP gives a very fast and reversible
fluorescence response to Cd2+ in the presence of the metal ions tested.
The complex stoichiometry between RhDP and Cd2+ was found to
be 1:1 and the binding constant was calculated as 2.70 × 107 M-1in ACN/HEPES buffer (10 mM,
pH: 7.05, v/v 1:1). The fluorescent detection limit of RhDP for Cd2+
was found to be 0.218 µM, which gave a marked sensitivity towards Cd2+.
