Unusual phenolphthalein-based fluorescent sensors for medium-selective multi-ions sensing in real samples
Özet
This study aimed to synthesize unusual phenolphthalein-based probes (PPs) and explore their photochemical properties. Synthesized PPs were investigated for their interactions with various ions in aqueous solutions using UV-Vis and fluorescence spectroscopy. PP1 exhibited turn-on fluorescence responses to Al3+, Cd2+, and Zn2+ ions at pH 7, while PP2 responded specifically to Zn2+ ions. Notably, pH-dependent selectivity was observed for PP1, with Al3+ and Zn2+ ions triggering turn-on responses at pH 5 and 9, respectively. Limit of detection (LOD) values and association constants (Ka) were determined for these interactions. Additionally, reversible on/off switching behavior was demonstrated for PP1/PP2 upon alternate addition of AlCl3/ZnCl2 and [Bu4N]OH. The effectiveness of PPs for real-world sample analysis was confirmed. Furthermore, the PP2-Cd2+ complex exhibited irreversible binding with cyanide and thiocyanide ions.
