Abstract:

The thesis consists of two major research topic i.e. Porphyrin and Nano crystalline cellulose. The porphyrin project started with the production of porphyrin chromophores for dye sensitized solar cells. These derivatives were required as references for an ongoing project of the research group that hosted me. In addition, some porphyrin-porphyrin tweezers were prepared using a one pot synthetic methodology developed in our lab, based on the use of trichloro triazine as a linker. These derivatives were necessary for collaboration with Professor Nina Berova at Columbia University that studies

Abstract:

The ubiquitin proteasome system (UPS) is the primary degradation system in eukaryotic cells, with high selectivity for a myriad of soluble proteins, and perturbations in the UPS are associated with numerous human disorders. For this reason the proteasome has become a pharmacological target for cancer and neurodegenerative diseases where opposite effects are desirable, inhibition and activation respectively. Interestingly, accumulation of the ubiquitin-conjugated proteins, which have been tagged for degradation, but not efficiently degraded have been observed at advanced age in many tissues. Si

Abstract:

The Ph.D work was aimed to design, synthesize, and test capabilities of new spermine-porphyrin and BODIPY derivatives, and to study their interactions with various biological targets. The research period was focused on the synthesis of porphyrin derivatives with a different number of spermine pendants, in order to combine the hydrophobic and hydrophilic behaviour in a single molecule with the possibility to modulate the two properties, but meanwhile also to have biocompatible features. In particular, polyamine arms make these compounds quite soluble in aqueous solution and let them to interac

Abstract:

Anthraquinone (AQ) derivatives with relatively high reduction potentials have been synthesized to afford good candidates for electron transfer studies in DNA. Electron withdrawing groups on the anthraquinone ring gave derivatives with less negative reduction potentials. The anthraquinone imide (AQI) derivatives had reduction potentials less negative than AQ derivatives. The AQI ring system was subject to base-induced hydrolysis.

We use scanning electron microscopy and transmission electron microscopy as tools to identify the self-assembled structures of porphyrin derivatives. It is observed that the formation of different nano-morphologies such as nano-rod or hollow sphere can be manipulated either by the structural features and/or solvent compositions. In this regard, T-dicZnP with hydrophobic substitutions forms one-dimension rods

Abstract:

碩士<br>國立臺灣師範大學<br>化學系<br>102<br>Zinc is an essential metal ion in biology system. Over three hundred enzymes contain zinc in human body. Zinc locates in the catalytic center and stabilizes metalloenzymes. They play important roles in bio-relate catalytic reactions. Therefore, the development of a zinc sensing molecule is extremely important. In 2009, our lab published the first porphyrin derivative as zinc sensing molecule, m-benziporphodimethene (BPDM). The later study shows that tripyrrinone would be a new generation of effective zinc sensing molecules and even has potential to be developed

博士<br>國立交通大學<br>應用化學系碩博士班<br>101<br>The thesis is composed of three topics. In the first part, to understand the relation between the solid-state phase structures and the photophysical properties of Poly (2,3-diphenyl-1,4-phenylene vinylene) (DP-PPV) derivatives, three DP-PPV derivatives, P1-P3 were designed, synthesized via Gilch polymerization and characterized. Among the polymers, P1 is a reported highly emissive poly(2,3-diphenyl-5-hexyl-p-phenylene vinylene), and P2, and P3 are novel DP-PPV derivatives, which are purposely designed to bear hydrophobic and hydrophilic Percec-type dendrons

Porphyrin derivative used in this research was tetrakis(4-carboxyphenyl)porphyrin (TCPP), whereas graphene derivatives used were graphene oxide (GO) and reduced graphene oxide (RGO). It began with a synthesis of composite (GO-TCPP) by non-covalent strategy through aromatic ??{? stacking and a synthesis of reduced graphene oxide through chemical r

In our previous study, porphyrin dyes modified with pyrene, N-N-dimethylaniline or athracene as the substituent showed improved solar cell efficiencies. So we linked anthracene with pyrene or aniline derivatives as the substituent of porphyrin dyes, in order to further improve the efficiencies of the dyes. In order to improve the aggregation of porphyrin dyes on TiO2 surface, we chose two kinds of long alkoxy chain to modify the

Abstract:

Halogenated porphyrins, which are catalysts for the oxidation of alkanes, were studied by semiempirical AM 1 calculations. The calculations predicted the effects of halogenation of the porphyrin ring on UV-visible absorption spectra and electrochemical data. Predictions regarding the stability of catalysts were made, and have been experimentally verified. INDO/S semiempirical calculations were performed on a series of porphyrins to understand the effects of a highly disfavored distortion that is conserved in cytochromes c. The highest occupied molecular orbitals were destabilized, and the orbi
