Gold Nanoclusters are of particular interest due to their many possible applications across a wide range of scientific fields. More specifically, nano-sized gold particles have potential to be used in drug delivery systems, cancer therapy and catalysis. This dissertation focuses on improving our understanding of ligated gold nanoclusters by examining the role of a variety of phosphine based ligands, novel methods to produce monodisperse solutions, and investigating the kinetics of water soluble ligated gold nanoclusters. The addition of ligands to solutions of Au have shown to produce small (<

Cette thèse examine les défis posés par l’accès incertain aux éléments chimiques, exacerbée par un paradigme économique linéaire de leur exploitation. L’étude se concentre sur le bore et le phosphore, dont l’utilisation et le recyclage restent sous-étudiés. Le bore, crucial dans diverses industries, nécessite des processus énergivores pour être transformé en hydroboranes actifs, utilisés en chimie fine. Deux voies existent pour leur synthèse : la méthode industrielle à partir de borate, et la réaction de BCl₃ avec un donneur d’hydrure. Utiliser H₂ comme agent réducteur pourrait améliorer ces p

Cyclodextrins (CDs) are cyclic oligosaccharides of various sizes containing several α-(1→4)-linked D-(+)- glucopyranose units. The commercially available ones comprise six, seven or eight glucose units, named respectively α-CD, β-CD and γ-CD. Their truncated cone-like and well-defined cavity are particularly attractive for the encapsulation of a variety of substrates. As such, they found numerous applications in many areas of chemistry. A recent development, from which the present work is inspired, consisted in covalently linking transition metals to CD cavities in order to perform and study c

The kinetics for the bridge-to-chelate isomerization of the dppe ligand in H4Ru4(CO)10(dppe) have been investigated by UV-vis and NMR spectroscopies over the temperature range of 308-328 K. The isomerization of the ligand-bridged cluster 1,2-H4Ru4(CO)10(dppe) was found to be reversible by 31P NMR spectroscopy, affording a Keq = 15.7 at 323 K in favor of the chelating dppe isomer. The forward (k1) and reverse (k-1) first-order rate constants for the reaction have been measured in different solvents and in the presence of ligand trapping agents (CO and PPh3).

碩士<br>高雄醫學大學<br>醫藥暨應用化學研究所碩士班<br>96<br>The preparation and characterization of RuCl2(POMe)2 (POMe = diphenyl(2-methoxyphenyl)phosphine) was reported. However, the reactions of RuCl2(POMe)2 with refluxing RCN (R = Me, Et) led to loss of CH3Cl to give Ru(RCN)2(PO)2 (R = Me(1), Et(3)), which are never reported. Adding KPF6 or KBF4 in the reactions will give additional products [Ru(RCN)2(PO)(POMe)]+ (R = Me(2), Et(4)) according to the solvent selection. Complexes 2 and 4 were observed the dealkylating via loss of CH3Cl or [CH3(POMe)]+ pathways. The [CH3(POMe)]+ pathway needs excess POMe which may

博士<br>國立清華大學<br>化學工程學系<br>105<br>Phosphorus-rich transition metal phosphide CuP2 nanowires were synthesized with high quality and high yield (∼60%) via the supercritical ﬂuid−liquid−solid (SFLS) growth at 410 °C and 10.2 MPa. The obtained CuP2 nanowires have a high aspect ratio and exhibit a single crystal structure of monoclinic CuP2 without any impurity phase. CuP2 nanowires have progressive improvement for semiconductors and energy storages compared with bulk CuP2. Being utilized for back-gate ﬁeld eﬀect transistor (FET) measurement, CuP2 nanowires possess a p-type behavior intrinsically wi

yes<br>The complexes [RuCp*(PP)Cl] (Cp* = C5Me5; [1], PP = dppm; [4], PP = Xantphos), [RuCp#(PP)Cl] (Cp# = C5Me4(CH2)5OH; [2], PP = dppm; [5], PP = Xantphos) and [RuCp*(dppm)(CH3CN)][SbF6] [3] were synthesized and evaluated in vitro as anticancer agents. Compounds 1–3 gave nanomolar IC50 values against normoxic A2780 and HT-29 cell lines, and were also tested against hypoxic HT-29 cells, maintaining their high activity. Complex 3 yielded an IC50 value of 0.55 ± 0.03 μM under a 0.1% O2 concentration.

<p>The work presented in this thesis explores two distinct fields of organometallic chemistry with a common goal of selectively transforming cheap and abundant feedstocks to value-added chemicals using homogeneous catalysts.</p> <p>Chapter 1 presents the synthesis and characterization of a series of bis(diphenylphosphino)amine ligands and their corresponding chromium(III) trichloride complexes. The isolated chromium complexes are precursors to highly active catalysts for the selective oligomerization of ethylene to 1-hexene and 1-octene.

It is anticipated the information provided from this study can bring insights for understanding the metal-sulfur chemistry in biological systems as well as in toxicity. In this thesis, diphosphine-dithiolate ligand (P2S2) was utilized for exploring metal chemistry. 31P, 207Pb NMR in solid and solution state were applied on two lead(II) compelexes, Pb(P2S2”) (1) and [Pb(P2S2”)]2·[Pb2(P2S2”)2] (2).
