Abstract:

The speciation and distribution of zinc (II) within cells is not well established and the range of zinc (II) probes available are of limited use. The quest was to develop responsive lanthanide complexes to bind selectively and respond (by change in hydration state) to biologically relevant concentrations of zinc at physiological pH for possible application in MRI and luminescence. A pyridyl sulfonamide ligand with an a-CH(_2)NHSO(_2)CF(_3) substituent was found to have the desired properties for strong zinc (II) coordination. The presence of a methyl group at 6', inhibited the formation of rel

Abstract:

Gas phase metal-containing complexes provide suitable systems in which to study fundamental binding motifs between a metal ion and molecules in the absence of any solvent, support or competing charge effects. In this thesis, metal-containing species are explored experimentally using infrared resonance enhanced photodissociation (IR-REPD) spectroscopy and velocity map imaging (VMI). The experimental results are further interpreted with the aid of spectral simulations based on density functional theory (DFT). These are the first studies reported using a newly built IR-REPD spectrometer equipped

Abstract:

Metal-hydrocarbon complexes were prepared in a laser-vaporization molecular beam source and studied by single-photon zero electron kinetic energy (ZEKE) and mass-analyzed threshold ionization (MATI) spectroscopy. The ionization energies and vibrational frequencies of the metal complexes were measured from the ZEKE and MATI spectra. Metal-ligand bonding and low-lying electronic states of the neutral and ionized complexes were analyzed by combining the spectroscopic measurements with quantum chemical calculations and spectral simulations. In this dissertation, the metal complexes of mesitylene,

Abstract:

Popular catalytic cycles, such as the Heck, Suzuki, and Negishi, utilize metal centers that oscillate between two oxidation states (II/0) during the three main steps of catalysis: reductive elimination, oxidative addition, and transmetallation. There has been a push to use less toxic, cheaper metal centers in catalytic cycles, leading to interest in first-row transition metals, such as nickel and cobalt. With these metals, the cycles can potentially pass through the +1 oxidation state, which acts as reactive intermediates, undergoing oxidative additions to form products, potentially with radic

That modeling method was then used in comparison with experimental infrared multiple photon dissociation (IRMPD) spectroscopy to determine the structures of metal-chlorate anions. In ad

博士<br>國立中興大學<br>生物科技學研究所<br>101<br>Danshen (Salvia miltiorrhiza), a traditional Chinese medicine, has been extensively used for the treatment of coronary artery heart disease. Recently, the major soluble ingredient of Danshen, magnesium lithospermate B (Mg-LSB) has been demonstrated to be a strong inhibitor of Na+/K+-ATPase and regarded as the active ingredient responsible for the treatment of coronary heart disease. Since Mg-LSB possesses a relatively rigid structure as a result of the formation of salt bridges between Mg2+ and the four oxygen atoms of the carboxyl groups that originated from

Abstract:

The synthesis of trans-11b,11c-dimethyl-11b,11c-dihydro-7H-cyclopent [a] pyrene, 109, from trans-10b,10c-dimethyl-10b,10c-dihydropyrene, 32, was achieved in six steps in an overall yield of 29%. Deprotonation of 109 gave the first annuleno-fused cyclopentadienide, trans-11b,11c-dimethyl-11b,11c-dihydrocyclopent[a] pyrene, ion(1-), 101. Experimental and theoretical proton NMR results for the anion in the presence and absence of the counter cation were analysed. The cyclopentadienyl anion, when fused to 32, has 53% of the effective bond-fixing ability of benzene fused to the same system. In term

博士<br>國立交通大學<br>材料科學與工程學系所<br>105<br>Various hydrogen-bonded (H-bonded) bent-core liquid crystal complexes consisting of pyridyl and benzoic acid derivatives were synthesized and compared with their covalent analogues in this study. The molar ratios of pyridyl and benzoic acid derivatives could be tuned to form various H-bonded liquid crystal (LC) diads (with 1 : 1 molar ratio of H-acceptors T and H-donors D) and complexes (with different molar ratios of T and D). By insertion of H-bonds into different positions of bent-core supramolecules, the mesophasic properties of H-bonded bent-core LC co
