AI Technical Summary
Existing palladium ion detection methods suffer from problems such as complex operation, expensive equipment, low sensitivity, poor specificity, and low detection accuracy. Furthermore, fluorescent probes are prone to fluorescence quenching or slow recognition rates in practical applications.
A novel fluorescent probe with the molecular formula C29H19O3N3S was prepared by reacting triethylamine with phenyl thiochloroformate under organic alkaline conditions. Using tricyanofuran as the fluorescent backbone and thiocarbonate as the recognition site, rapid, highly sensitive and highly selective detection of palladium ions was achieved.
This fluorescent probe exhibits excellent selectivity and anti-interference ability, can rapidly identify palladium ions, enhances fluorescence intensity, and achieves a Stokes shift of 180 nm, making it suitable for bioimaging in onion inner epidermal cells and zebrafish.
