Herein, we introduce new ratiometric 2,4,6-triamino-1,3,5-triazine-based probes (R1and R2) having three different binding sites for three metal ion binders, which can selectively detect Zn2+ions and, particularly, the probe R1strongly interacts with the human lung cancer cell line (A549). Both the probes R1and R2are competently selective towards the Zn2+ions with the detection limits of 1.22 × 10−7M and 1.13 × 10−7M, respectively. The changes in the structure and absorption properties of the probes are explained by density functional theory (DFT) and time dependent density functional theory (TDDFT) calculations. The absorption and fluorescence color change in the solid TLC plate makes it a brilliant Zn2+sensor in a portable form.
