A novel and simple light-up fluorescent probe (PASPy-al) with a D-π-A structure based on AIE as well as ESIPT processes was designed for highly selective discrimination of Pd2+ and Pd0. PASPy-al displayed a large Stokes shift (95 nm), a high light-up ratio (116 fold) and a low limit of detection (LOD: 96 nM) toward Pd0. Moreover, the practical applications of PASPy-al for detection of Pd0 in environmental, human urine and pharmaceutical samples were realized, indicating the unique advantages of designing anti-ACQ fluorescent probes based on AIE and ESIPT mechanism. Fluorescence imaging of Pd0 in live cells was realized by using PASPy-al. Furthermore, imaging of Pd0 generation in live cells was also realized by in situ reduction of Pd2+ to Pd0 in the presence of reducing agent like CO, indicating the potential ability of this probe for further fluorescent imaging of cellular reducing agent. The easy preparation of probe PASPy-al plus their excellent parameters would make it a simple to handle probe for detection of Pd0 both in practical samples and in live cells. In the experiment, the researchers used many compounds, for example, Pyridin-3-ylboronic acid(cas: 1692-25-7Related Products of 1692-25-7)
Pyridin-3-ylboronic acid(cas: 1692-25-7) belongs to pyridine. When pyridine is adsorbed on oxide surfaces or in porous materials, the following species are commonly observed: (i) pyridine coordinated to Lewis acid sites, (ii) pyridine H-bonded to weakly acidic hydroxyls, and (iii) protonated pyridine. At high coverage, physisorbed pyridine and protonated dimers can also be observed.Related Products of 1692-25-7
