Abstract: Abstract of the thesis entitled DESIGN, SYNTHESIS AND FUNCTIONALIZATION OF LUMINESCENT ALKYNYLGOLD(I) COMPLEXES WITH π-CONJUGATED LIGANDS  FROM PHOTOPHYSICS TO SUPRAMOLECULAR ASSEMBLY Submitted by HONG Yau Hin for the Degree of Doctor of Philosophy at The University of Hong Kong in July 2015 A library of polynuclear thiophene-based alkynylgold(I) complexes with N-heterocyclic carbenes (NHCs) and triphenylphosphine as the peripheral ligands, [R{(C≡C)Au(NHC)} ] (R = benzo[1,2-b:4,5-b']dithiophene, n = 2, 4; benzo[1,2- b:3,4-b':5,6-b'']trithiophene, n = 3; dithieno[3,2-b:2',3'-d]thiophene, n = 2; dithieno[3,2-e:2',3'-g](dibenzo[b, d]-thiophene), n = 2; 4-hexyl-4H-dithieno[3,2- b:2',3'-d]pyrrole, n = 4) and [R'{(C≡C)Au(PPh )}] (R' = benzo[1,2-b:4,5- 3 2 b']dithiophene), has been synthesized and characterized. The X-ray crystal structure of [BDT{(C≡C)Au(IHex)} -2,6] (BDT = benzo[1,2-b:4,5-b']dithiophene, IHex = 1,3-dihexylimidazol-2-ylidene) has been determined by X-ray crystallography. This class of complexes showed dual emissive behaviour and exhibited broad vibronic-structured emission bands in degassed dichloromethane solution at ambient temperature. As demonstrated by the temperature-dependent UV-vis absorption spectroscopy, some of the alkynylgold(I) complexes were shown to self-assemble in THFwater mixtures through a cooperative growth mechanism. Variation of the alkyl chain length on the NHC ligands not only has a significant effect on the morphologies of the aggregates, but also on the thermodynamic parameters of the self-assembly processes as revealed by the nucleationelongation model. Apart from the thiophene-based sulfur heterocycle-containing alkynylgold(I) system, a series of N-alkyl substituted triindole-based nitrogen heterocycle-containing trinuclear alkynylgold(I) complexes with isocyanide and NHCs as the peripheral ligands, [(TATI){(C≡C)Au(C≡N-R)}] (TATI = trialkyltriindole; R = 2,6-dimethoxyphenyl, 2,6-dimethylphenyl), and [(TATI){(C≡C)Au(NHC)}], has been prepared and characterized. The photophysical properties of the trinuclear alkynylgold(I) complexes have been examined. Their self-assembly properties have also been explored using TEM, SEM, DLS, H NMR spectroscopy, solvent-dependent and variable-temperature UV-vis absorption experiments. Some of the complexes have been demonstrated to possess spherical nanostructures in their THFwater dispersions. The self-assembly was believed to be mediated by the ππ stacking interactions of the central triindole moiety and governed by a cooperative growth mechanism. In addition, a novel class of amphiphilic phosphole-based phosphorus heterocycle-containing alkynylgold(I) complexes, [Au(C≡C-R){Ph-DBP(O)-  ] O(CH ) SO }]K (DBP = 5H-dibenzophosphole; R = phenyl, naphthyl, 2 3 3 phenanthrenyl, pyrenyl, perylenyl, 4-methoxyphenyl, 4-chlorophenyl) was designed and synthesized. The photophysical properties of this class of complexes have been studied. Some of the complexes were shown to display sheet-like nanostructures in aqueous DMSO solution. The self-assembly process was found to be governed by an isodesmic mechanism and mediated by hydrophobichydrophobic interactions between the alkynyl units. It has been shown that modulation of t

Book The Design and Synthesis of Organic Chromophores for Faraday Rotation and Photoluminescence

Download or read book The Design and Synthesis of Organic Chromophores for Faraday Rotation and Photoluminescence written by Zachary Nelson and published by . This book was released on 2021 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis summarizes the design, synthesis, and application of novel small-molecule and polymeric materials, with emphasis on understanding and tuning the chromophore electronic structure to maximize properties including Faraday rotation and delayed fluorescence. In Chapter 1, we introduce the magneto-optical property Faraday rotation. The current frontiers in performance, applications, and mechanistic understanding of Faraday rotation in organic-chromophore thin-films is discussed. Faraday rotation measurements of several novel materials are introduced in context. In Chapter 2, we evaluate the Faraday rotation in thin films of several phthalocyanine and porphyrin derivatives, and observe maximum Verdet constants greater than those found in competing inorganic materials. The effect of chemical modifications, including the introduction of paramagnetic and chiral centers, is discussed. In Chapter 3, we evaluate the Faraday rotation in thin films of pi-conjugated polymers when influenced by chiral moieties. We demonstrate the key role chirality serves in the magneto-optical properties of these materials, the influence of structural order and film thickness on Faraday rotation, and report among the largest Verdet constants observed to date in organic thin films. In Chapter 4, we develop the polymerization for and evaluate the properties of a new class of polyarylene chalcogenides. We utilized dynamic covalent SNAr behavior to demonstrate selective depolymerization. In addition, we studied the mechanism of the bright photoemission, ascribing it to delayed fluorescence enabled by the presence of sulfur atoms. In Chapter 5, we discuss the synthesis and properties of two classes of solution-processable materials: M(III) and Au(I) arylthiolate coordination polymers. We demonstrate the presence of strong metal-metal interactions between M(III) centers along the polymer backbone. Further, we discuss the strong phosphorescence and dynamic supramolecular coordination in the solution phase of the Au(I) coordination polymers.

Book Modern Colorants  Synthesis and Structure

Download or read book Modern Colorants Synthesis and Structure written by A.T. Peters and published by Springer Science & Business Media. This book was released on 1994-12-31 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the research actIvItIes of dyestuff chemists worldwide have been influenced to a great extent, in recent years, by the need to respond to a variety of environmental issues associated with the manufacture and application of synthetic dyes and pigments, a significant level of targeted research continues to be devoted to new chemistry aimed at enhancing the technical properties of dyes in commerce. This book is a presentation of various aspects of basic research conducted during the past decade but not reported in the recent review literature. The coverage herein is unique in that it emphasizes systematic approaches commonly utilized in the design and synthesis of dyes and pigments and the required intermediates. While it is well known that certain transition metals are important in the synthesis of technically viable metallized dyes for polyamide and protein fibers, these metals are demonstrated in Chapter 1 also to be effective agents in the regiospecific placement of substituents into azo compounds. The scope and limitations of this chemistry are presented. In other synthetic work, a description of the different processes employed to produce the major families of reactive dyes is presented. In Chapter 4, special attention is given to reactive dyes containing more than one reactive group, and to the more recent developments in the field. The two chapters which follow provide a review of the recent literature pertaining to novel chromophores and dyes for the D2T2 process, respectively.
