Abstract:

This thesis describes the synthesis of some biphenyl-biphenyl analogues for the treatment of diabetes. Researchers at Curtin University of Technology have reported the discovery of small molecule insulin mimetics. One of the reported compounds (IM140) is active in an animal model of diabetes. The structure of IM140 comprises of a biphenyl left hand side, a linker and a xanthone right hand ring fragment (right hand side). The key features of IM140 are believed to be the biphenyl moiety on the left hand side and the two carboxylic acids from the right hand side. The primary goal of this thesis i

Abstract:

Platinum(II) biphenyl diimine complexes have been synthesized and characterized. Single crystal X-ray structures from seven complexes show two types of configurations about the platinum coordination sphere in the solid state: X and B (butterfly). The two configurations give different circular dichroism spectra (CD) based on their C2 or Cs symmetry. The metal-to-ligand charge transfer (MLCT) bands which occur at ~440 nm are transitions from d orbitals on the platinum metal center to * orbitals of the diimine ligands. This agrees with the time dependant density functional theory (TDDFT) calcula

碩士<br>國立成功大學<br>化學工程學系碩博士班<br>92<br>Since the discovery of electroluminescence (EL) of poly(p-phenylene vinylene) (PPV), polymeric light emitting diode (PLED) have attracted much attention. Currently one of the biggest problems for PLED as commercially viable displays is the low quantum efficiency. Most PPV-related polymers can be easily p-doped, so the mobility of holes is usually much greater than that of electrons, which may result in imbalance of electron- and hole-injection that leads to low EL efficiency. This problem is usually solved by device engineering, or development of highly effi

In the synthetic process of compound 51, we get the final compound using faster, safer and more convenient method different from the original one. We also remove the doubts about compound 49 may decompose and investigate its crystal structure properties.

These compounds possess scissor-like conformations which were evidenced by using the spectroscopic and electrochemical methods, as well as by X-ray crystallography. The presence of the ample conformational variations influences their photoluminescence and morphological stability: (1) the scissor-like structures would breakdown the intramolecular pi-conjugation of the molecule, (2) The non-coplanar structure would also hamper the intermolecular stacking, prohibitin

All compounds were characterized by 1H and 13C-NMR spectroscopy. Their mesomorphic properties were studied by differential scanning calorimetry (DSC), polarized optical microscopy (POM) and powder x-ray diffraction (XRD). These molecules have two ester linkages (1a, 1b, 2a, 2b), two (1c, 1e, 2c, 2e), and four alkoxy sidechains (1d, 1f, 2d, 2f). The compounds have been synthesized by Schiff base from 1a

The conformational and substitution effects were studied by photophysical properties and cyclic voltammetry. For the fluorescence and phosphorescence of 2,2’-(1,3,4-oxadiazo-2-yl)biphenyl(BOBP) showed good spectra matching with absorption spectra of MLCT1 and MLCT3 transition of Ir(ppy)3. While BOBP was used as host material for Ir(ppy)3 in PHOLED device, the maximum brightness of 43,000 cd/m2 with efficiency of 26 cd/A at 200 cd/m2 was achieved. The first-reduction pote
