Abstract:

Diverse conformational transitions and aggregations of regioregular head-to-tail polyhexylthiophene in different environments have been studied by means of AFM and UV-vis spectroscopy. A helical conformation of the main chain with 12 thiophenes rings per each helical turn has been proposed. Length of the particles varies from several nanometers to several hundreds nanometers and can be adjusted by the solvents composition or concentration of PATs. Such well-defined organic semiconductor 1D particles can be used as building blocks for future nanoscale and molecular level electronic devices. Oli

Abstract:

Living polytetrahydrofuran (PTHF) was terminated with sodium thiophenemethonate to yield a polymer with thiophene groups at one (PTHF1) and both ends (PTHF2). Copolymerizations of PTHF1 and PTHF2 insulating polymers with pyrrole and thiophene were achieved in water-p-toluene sulfonic acid (PTSA) and acetonitrile (AN)-tetrabutylammonium tetrafluoroborate (TBAFB) solvent-electrolyte couples via constant potential electrolysis. Characterization of the samples were performed by Nuclear Magnetic Resonance Spectroscopy (NMR), cyclic voltammetry (CV), Fourier Transform Infrared Spectroscopy (FT-IR),

Abstract:

Electronic conductive polymers such as polyacetylenes, polyanilines and polythiophenes, are not easy to process due to lack of tractability and solubility. Chemical modifications of the polythiophenes backbone have been utilized to improve the processibility. Our goal is to synthesize and characterize 3-[oligo(dimethylsiloxane)]- thiophene macromonomers as precursors for potentially processible, conductive derivatives of polythiophene. The precursor will be used in the preparation of various poly {[3- oligo(dimethylsiloxane)]thiophene-co-3-methylthiophene} random copolymers. By increasing the

Biohybrid derivatives of π-conjugated materials are emerging as powerful tools to study biological events through the (opto)electronic variations of the π-conjugated moieties, as well as to direct and govern the self-assembly properties of the organic materials through the organization principles of the bio component. So far, very few examples of thiophene-based biohybrids have been reported. The aim of this Ph.

Here we propose, for the first time, a new and green ethanol-thermal reaction method to synthesize highquality and pure thiophene–sulfur doped reduced graphene oxide (rGO), which establishes an excellent platform for studying sulfur (S) doping effects on the physical/chemical properties of this material. We have quantitatively demonstrated that the conductivity enhancement of thiophene–S doped rGO is not only caused by the more effective reduction induced by S doping, but also by the doped S atoms, themselves. Furthermore, we demonstrate that the S doping is more effective in enhancing conduct

Side chain liquid crystalline polythiophenes have been synthesised and investigated in order to study the effects of liquid crystalline moieties on the polymer and their possible effect on the electronic properties.

This synthesis was followed by the attachment of mesogens through a six-methylene unit spacer to 3-thiophene methanol and the preparation of thiophene-based monomers. The chemical structure of the prepared monomers was confirmed by characterisation techniques suc

Adenosine and adenosine analogues are recognised as cardioprotective agents due to the responses that they induce through the activation of myocardial adenosine receptors.

It was envisaged that the linking of an antioxidant moiety to adenosine would produce an adenosine analogue that activates adenosine receptors and also scavenges oxygen-derived fre

Abstract:

碩士<br>國立臺灣大學<br>化學研究所<br>104<br>Poly(3-hexylthiophene) (P3HT) has been widely used in organic photovoltaics because of its ease of synthesis, high hole mobility, and relatively efficient light absorption in the visible-light range. However, due to the high crystallinity of P3HTs, most of them assembled into lamellar structures. Therefore, in order to explore other possible morphologies, our strategy is to synthesize a series of well-defined P3HT-based star-like copolymers containing branched alkylated thiophene monomers. The star-like homopolymers were composed of polyphenylacetylene or polyt

Abstract:

碩士<br>國立交通大學<br>應用化學系碩博士班<br>101<br>In this study, two series of conjugated polymers were synthesized for the application of organic thin film transistor（OTFT）. For the first series, a hexacylic ladder monomer（TTDT） consisting of two thiophenes and a thieno[3,2-b]thiophene ring was synthesized. The TTDT monomer was copolymerized with thiophene（T）, thieno[3,2-b]thiophene（TT）, bithiophene（2T）to form the alternating copolymers PTTDT-T, PTTDT-TT and PTTDT-2T. The OTFT devices based on PTTDT-T, PTTDT-TT and PTTDT-2T show the mobilities of 1.52×10-3, 1.62×10-3, 2.83×10-3 cm2s-1V-1 respectively.

Abstract:

碩士<br>國防醫學院<br>藥學研究所<br>94<br>Our laboratory previously carried out the design and synthesis of a series of benzothieno[2,3-c]quinolone derivatives to develop novel anticancer drugs in our laboratories. After screening of the radiosensitizer/radioprotectant, the results showed that benzothiophene intermediates had strong potency to enhance the activity of radiation. On the other hand, literatures indicated that some thiophene derivatives possess significant antiinflammatory activity. Therefore, we further designed and synthesized a series of benzothiophene and thiophene derivatives to develop
