Abstract:

The IR spectra of twenty-one transition metal complexes of 8-hydroxyquinoline over the range 700 - 50 cm⁻¹ are discussed in relation to their known or inferred structures. The complexes are of three types: (a) the bis(aquo) complexes of the first row transition metal(II) ions, [M(ox)₂(H₂O)₂] (M =Mn, Fe, Co, Ni, Cu, Zn); (b) the corresponding anhydrous complexes, [M(ox)₂]n (M=Mn, Co, Ni, Cu, Zn) and (c) the complexes of the metal(III) ions, [M(ox)₃] (M = Sc, V, Cr, Mn, Fe, Co, Ga, Rh and In).

Abstract:

Derivatives of the quinoline moiety have been shown to exert a range of biological activities, including anti-neoplastic activity. The clinical application of quinoline derivatives in the treatment of malignancies has been limited due to non-selectivity. Four novel hydroxyquinoline derivatives were synthesised as potential anticancer agents. Each of these compounds contains the characteristic quinoline nucleus: a heterocyclic moiety containing a nitrogen atom. A hydroxyl group is present on C-8 and an azo bond links the heterocyclic quinoline core to a monocyclic benzene ring with various subs

Diffusive gradient in thin film technique (DGT) represents a relatively new approach for in situ determinations of labile metal-species in aquatic systems. The DGT device passively accumulates labile species from the solution while deployed in situ, and therefore contamination problems associated with conventional collection and filtration procedures are eliminated. This study deals with a possible modification of DGT technique. The key of using DGT technique for speciation analysis of metals is to find out suitable binding phase and diffusion layer.

All important factors such as time, pH, reagent concentration, buffers, surfactants and selected interferents have been studied with respect to the selectivity, sensitivity, precision and detection limit on the determination by using classic fluorescence spectra and their first derivation. This reagent was also used for the determination of scandium in real waters. The new reagent was shortly compared to morin and lumogallion when used for scandium.

In my studies of the magnetic field effect on photoluminescence (PL), the ISC rate, kISC, is estimated by modelling the dependence of the PL under high excitation intensity.

碩士<br>國立交通大學<br>生物科技學系<br>99<br>Over the past few years, more and more evidence indicated that the metal ion imbalance in the brain will give rise to many diseases. Magnetic resonance imaging (MRI) is a non-invasive and high resolution technique that has become a powerful diagnostic tool in medicine. In this study, we have developed a new contrast agent [Gd(HQ-DO3A)] that can recognize Cu2+ ion in the cells. The significant increases in the relaxivity (r1) and hydration number (q) in the present of Cu2+ were observed. Moreover, the Gd3+ complex attributes excellent selectivity for Cu2+ over a

The concentrated sample was then further analyzed for Cu, Cd by Graphite atomic absorption spectrometry (GAAS). After characterized the synthesized 8-HQ, it found that 8-HQ chelating agent possesses high stability against the fluctuation of the pH value and it will not lose its chelating ability while it was exposed to the tes

For 5-member heterocyclic derivatives, the basicity of the quinoline ring are enhanced in excited state (pKa ⊿= 8 ~ 10). Comparing with thiophene derivatives, pyrrole ring possesses a stronger electron-donating ability. However, these molecules all practiced an excited state proton transfer (ESPT) reaction in strong hydr

Abstract:

Yes<br>One-pot reaction between 8-hydroxyquinoline-2-carboxaldehyde (HQC) and tris(hydroxymethyl)aminomethane (TRIS) followed by in situ cyclization yielded an oxazolidine based ligand which produced four mononuclear complexes of MnII(1), CoII(2), NiII(3), ZnII(4), a tetranuclear iron (FeIII4) complex (5) and a trinuclear cobalt (CoIICoIII2) complex (6). Magnetic studies show dominant antiferromagnetic interaction in tetranuclear iron (FeIII4) complex 5 and presence of the slow relaxation of magnetisation in 6. The compounds were also studied for their antibacterial properties. The oxazolidine

The impact of a tri-substituted boron moiety on the chelate sensitization of Tb(III) and Eu(III) lanthanide luminescence and their resulting photophysical properties was investigated. Two triarylboron-functionalized carboxylate ligands 1 and 2 and their respective Tb(III) and Eu(III) complexes, 1Tb, 2Tb, 1Eu and 2Eu were synthesized and fully characterized. The photophysical properties of these compounds were studied and it was established that these three-coordinate boron ligands are highly effective in selective activation of Tb(III) and Eu(III) luminescence yielding high efficiency green an
