Abstract:
There is a continuing need to make new antitubercular drugs due to development of resistance towards present drugs. To do this, series of pyruvate hydrazones (PVAHs) and their respective Cu(II) complexes and Zn(II) complexes were synthesized and fully characterised. Variable temperature NMR studies of PVAHs indicate the presence of E and Z isomers in the solution. Determination of the obtained single crystal X-ray structures reveals that Cu(II) ion binds to PVAH ligand in 1:1 ratio resulting in square pyramidal geometry in most of the Cu(II) complexes, whereas Zn(II) ion binds to two PVAH liga

Photocatalytic carbon dioxide reduction transforms CO2 to useful chemicals and fuels, reducing CO2 emissions and making fossil fuels more renewable.

The photon driven reduction of Zn(II) to zinc metal is a novel field of study with many potential applications including the use of zinc metal as a solar fuel.

As a solar fuel, zinc metal would be used in efficient zinc air batteries and then regenerated by the photocatalytic reduction of Zn(II) and a concurrent oxidation reaction.

In this PhD thesis the synthesis, characterization, and study of the aggregation/deaggregation properties of a series of amphiphilic bis(salicylaldiminato)ZnII Schiff base complexes, involving different bridging diamino groups, and their applications as molecular probes, nonlinear optical (NLO) and vapochromic materials, as well as synthons for the formation of new fibrillar and branched supramolecular nanostructures, are reported. Through detailed 1H NMR, DOSY NMR and optical spectroscopic studies, it is found that these species always form aggregates in solution of non-coordinating solvents

Abstract:
This thesis presents research in the field of transition metal complex chemistry. The major project, reported in Part I, is focussed on the mimicking of enzymes in order to produce simple catalyst molecules that enhance the rate of ester hydrolysis. This work involved a systematic characterisation of a suite of potential enzyme mimics which were based on the simple template molecules tris(2-aminoethyl)amine (tren) and 1,4,7-triazacyclononane (tacn). The effects of substituting tren and tacn with methyl groups and β-cyclodextrin and then complexing these with Zn²⁺, Cu²⁺, Cd²⁺ and Ni²⁺ were exam

Polypyridine d6 and d8 transition metal complexes have received a great deal of attention because of their wide applications in various areas such as photo-induced energy- and electron-transfer process, artificial photosynthetic centers, electroluminescent displays, dye-sensitized solar cell, and molecular-level machines, etc Compared to 2, 2'-bipyridine-type complexes, 2, 2':6', 2&Prime;-terpyridine(tpy)-type complexes have been much less thoroughly examined, because the weak ligand field of tpy-type ligands results in the weak emissive and short-lived excited states of their complexes.

博士<br>國立清華大學<br>化學系<br>93<br>Abstract Organometallics plays an essential role on organic synthesis in these decades. It was applied in coupling reactions, cyclization reactions or ring opening reactions. Organometallics catalyzed reactions not only have good regioselectivities but have good stereoselectivities. In natural products synthesis, it is very important to control stereo or regio direction in specific positions. We emphasize on ruthenium and zinc metal complex which apply in ethynyl alcohol catalyzed transfer reactions. First, ruthenium complex was applied on transformation of propar

Abstract:
Small molecule Zn(II) complexes containing N- and S- donor environments may serve as appropriate models for mimicking Zn protein sites, and thus, their reactions with heavy metal ions such as Pt(II) and W(0) may provide insight into possible adduct formation and zinc displacement. To study such possible interactions between zinc finger proteins and platinum-bound DNA, the ZnN2S2 dimeric complex, N,N?-bis(2- mercaptoethyl)-1,4-diazacycloheptane zinc (II), [Zn-1?]2, has been examined for Znbound thiolate reactivity in the presence of Pt(II) nitrogen ? rich compounds.
