Chiral molecules can generally exhibit different physiological and biological activities, thus triggering wide interest in chiral discrimination. Herein, we demonstrate a sensitive homoleptic cyclometalated iridium(III) complexes nanowires (Ir(piq)3 NWs) electrogenerated chemiluminescence (ECL) sensor for high-performance discrimination of chiral molecules based on the difference in electron-transfer ability between different radicals. The developed Ir(piq)3 NWs/ITO sensor exhibits high ECL signal and satisfying stability without the presence of co-reactant based on hot electron-induced ECL, which would spur its further application in detecting proline enantiomers. Obvious difference on the ECL intensity towards L-Pro and D-Pro is observed under the presence of high concentration of proline enantiomers, which attributes to the different electron-transfer capability between Ir+(piq)3 and L-pro?/D-pro?. In order to attain high-performance discrimination, we construct the Ir(piq)3 NWs/TPrA sensor to achieve chiral discrimination for trace amounts of proline enantiomers (1.0 × 10?9 M), which attributes to the strong molecular interactions enhanced by introduction of active radical TPrA?.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 344-25-2 is helpful to your research. Quality Control of: H-D-Pro-OH
