A facile surface-enhanced Raman scattering (SERS) substrate based on the self-assembly of silver nanoparticles on the modified silicon wafer was obtained, and for the first time, an advanced SERS analysis method basing on this as-prepared substrate was established for high sensitive and rapid detection of uranyl ions. Due to the weakened bond strength of OUO resulting from two kinds of adsorption...
Two new isomerous PET fluorescent chemosensors (L and L′) for Al3+ have been designed, synthesized and characterized. The two chemosensors exhibited fluorescence enhancement upon binding Al3+ in CH3CN by PET inhibition processes from both the sulfur and the nitrogen donors to anthracene. The job’s plot, Benesi–Hildebrand plot and 1H NMR titration experiments indicate that both chemosensors form a...
In this paper, a Re(I) complex of Re(CO) 3 (Bphen)Br, where Bphen=4,7-diphenyl-1,10-phenanthroline is synthesized, and doped into poly(vinylpyrrolidone) submicron fibers through electrospinning technique. Their morphology, absorption, and emission spectra are investigated in detail. The composite fibers exhibit smooth and uniform morphology on the substrate, with an average diameter of ∼800nm...
