摘要: Abstract A novel easily available off-on fluorescent and colorimetric probe based on rhodamine was synthesized. It showed selective sensitive recognition toward Cr 3+ in aqueous medium, with no significant interference of other competitive metal ions. The observed photophysical changes is due to the operation if internal charge transfer after addition Cr(III) ions probe. Density functional calculations (DFT) supported UV–vis absorption fluorescence emission changes. Furthermore, has been utilized for imaging HeLa cells under physiological conditions.
