  Nickel(II)-Induced Excimer Formation of a Naphthalene-Based Fluorescent Probe for Living Cell Imaging

  摘要：

  Ni2+-induced intramolecular excimer formation of a naphthalene-based novel fluorescent probe, 1-[(naphthalen-3-yl)methylthio]-2-[(naphthalen-6-yl)methylthio]ethane (L), has been investigated for the first time and nicely demonstrated by excitation spectra, a fluorescence lifetime experiment, and H-1 NMR titration. The addition of Ni2+ to a solution of L (DMSO:water = 1:1, v/v; lambda(cm) = 345 nm, lambda(ex) = 280 nm) quenched its monomer emission, with subsequent enhancement of the excimer intensity (at 430 nm) with an isoemissive point at 381 nm. The fluorescence lifetime of free L (0.3912 ns) is much lower than that of the nickel(2+) complex (1.1329 ns). L could detect Ni2+ as low as 1 x 10(-6) M with a fairly strong binding constant, 2.0 x 10(4) M-1. Ni2+-contaminated living cells of plant origin could be imaged using a fluorescence microscope.

  Method and apparatus for determining a quality or characteristic of connectors in electronic components is provided. Methods include applying a UV-responsive indicator solution active for Pd, Ni, or Cu to a connector on an electrical component; irradiating the connector with UV radiation; detecting a response to the UV radiation; and determining a quality of the connector based on the response to the UV radiation. Apparatus includes an enclosure; a support; a dispenser oriented toward the substrate support; a source of UV-responsive indicator solution active for Pd, Ni, or Cu ions fluidly coupled to the dispenser; a UV source coupled to the enclosure; and a radiation sensor positioned to detect light inside the enclosure.
