Herein, an easy assembled colorimetric and ''turn-on'' fluorescent sensor (probe P4SC) based on phenolphthalein was developed for carbonate ion (CO 3 2- ) sensing in a mixture of EtOH/H 2 O (v/v, 80/20, pH = 7, Britton-Robinson buffer) media. The probe P4SC demonstrated high sensitive and selective monitoring toward CO 3 2- over other competitive anions. Interaction of CO 3 2- with the probe P4SC resulted in a significant increment in emission intensity at λ em  = 498 nm (λ ex  = 384 nm) due to the strategy of blocking the photo induced electron transfer (PET) mechanism. 1 H NMR titration and Job's methods, as well as the theoretical study were carried out to support the probable stoichiometry of the reaction (1:2) between P4SC and CO 3 2- . The binding constant of the probe P4SC with CO 3 2- was calculated as 2.56 × 10 10  M -2 . The probe P4SC providing rapid response time (~0.5 min) with a satisfactorily low detection limit (14.7 nM) may be useful as a valuable realistic sensor. The imaging studies on the liver cancer cells (HepG2) shows the great potential of the probe P4SC for the sensation of intracellular CO 3 2- anions. Furthermore, the satisfactory recovery and RSD values obtained for water application confirming that the probe P4SC could be applied to sensing of CO 3 2- ion.
