Özet
Fluorescent sensors have attracted an important interest due to their advantages such as high selectivity, rapid response, easy 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-1 in acetonitrile (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+. © 2020, Turkish Chemical Society. All rights reserved.
