title: Construction of a near-infrared fluorescence turn-on and ratiometric probe for imaging palladium in living cells.
abstract: A new NIR fluorescent probe, NIR-Pd, for palladium species was designed and synthesized, based on a HD NIR fluorophore and deprotection of aryl propargyl ethers by palladium. The probe NIR-Pd displayed either a large NIR fluorescence turn-on or ratiometric response to palladium with high sensitivity and selectivity. Additionally, the novel NIR probe can monitor palladium species in live HeLa cells by NIR fluorescence imaging.
