    摘要： The hydrophobic and corrosion resistive film of cross-linked poly(hexafluoroisopropyl methacrylate) was prepared by photopolymerization. The starting materials were a monomer of 1,1,1,3,3,3-hexafluoroisopropyl methacrylate, a photoinitiator of hydroxycyclohexyl phenyl ketone, and a cross-linker of poly(ethyleneglycol diacrylate). Photopolymerization was used to start polymerization and to cure the polymer film on an aluminum surface. Drop-casting was used to deposit the fluoropolymer onto an aluminum substrate (AA 3003). The fluoropolymer film has high corrosion protection when measured by potentiodynamic polarization and open circuit potential techniques in an aqueous solution of 3.5% NaCl. Fourier-transform infrared spectroscopy was used to monitor the polymerization process. The dynamic contact angle technique was used to measure the hydrophobicity for the fluorinated polymer coating. Thermal stability of the fluorinated polymer was measured using thermogravimetric analysis. Treatment with strong acid followed by contact angle measurements before and after the treatment confirmed the chemical resistance for the coated aluminum.

    摘要： A phosphorescent chemosensor based on A Gold(I) complex stabilized in an aqueous polymer media. The complex exhibits strong red emission (λmax ˜690 nm) in solutions and is sensitive to sub-ppm/nM levels of silver ions. On addition of silver salt to the polymer-complex, a bright-green emissive adduct with peak maximum within 475-515 nm is developed. The silver adduct exhibits a four-fold increase in quantum yield (0.19±0.02) compared to polymer-complex alone (0.05±0.01), along with a corresponding increase in phosphorescence lifetime. The polymer-complex also exhibits sensitivity to higher concentrations (e.g., >1 mM) of other metal ions such as Tl+, Pb2+, and Gd3+. The sensing methodology is simple, fast, and convenient, and the results can be detected by the naked eye. Addition of EDTA restores the red emission of the complex. The complex can distinguish between silver ions and silver nanoparticles and can be used to remediate silver ions from the environment.

    摘要： Bidentate heteroleptic square planar complexes of (pyridyl)azolates possess optical and electrical properties that render them useful for a wide variety of optical and electrical devices and applications. In particular, the complexes are useful for obtaining white or monochromatic organic light-emitting diodes (“OLEDs”), including doping-free OLEDs. Preferred forms also demonstrate semiconducting behavior and may be useful in a variety of other applications. Within the general complexes of (pyridyl)azolates, the metal and the ligands may be varied to impart different optoelectronic properties.
