Abstract:

In this licentiate thesis the luminescence properties of two flexible conjugated dyes have been studied. The first, Pt1, is a platinum(II) acetylide chromophore used in optical power limiting materials. The second is a set of optical probes known as luminescent conjugated oligothiophenes (LCOs), which are used to detect and characterize the protein structures associated with amyloid diseases such as Alzheimer’s disease. MM3 and CHARMM force field parameters have been derived for the Pt1 chromophore and LCOs, respectively, based on potential energy surface references calculated at the density f

Abstract:

Fluorescence is widely used in DNA sequencing and genetic analysis. Novel fluorescence techniques for studying nucleic acids and other biologically important molecules are constantly being developed. In order to provide efficient probes with desired fluorescent properties, new fluorophores and nucleic acids labelling chemistries are required. The synthesis of various cyanine dyes derivatives is described in this thesis. Dyes were designed for NHS-ester and click chemistry labelling of oligonucleotides. Additionally the synthesis of disperse blue quencher and a 2′-mesyl-modified thymidine monom

Abstract:

Squaraine dyes are a subclass of polymethine dyes, which owing to its low band gap and strong absorption (ε >105 M−1 cm−1) in the far-red and NIR region have found application in dye-sensitized solar cells. While the squaraine dyes have excellent absorption in the far-red region, the exciton quenching by aggregation limits its overall performance in dye-sensitized solar cells. The aggregates form when the dipoles of the molecules interact with each other due to pi-pi interaction. When a molecule absorbs light and reaches excited state, the photoexcited electron in the LUMO state hops between t

Abstract:

Lack of crystalline order and microstructural features such as grain/grain-boundary in metallic glasses results in a suite of remarkable attributes including very high strength, close to theoretical elasticity, high corrosion and wear resistance, and soft magnetic properties. By altering the morphology and tuning of composition, MGs may be transformed into high-performance catalytic materials. In this study, the catalytic properties of metallic glass powders were demonstrated in dissociating toxic organic chemicals such as AZO dye. BMG powders showed superior performance compared to state of t

Abstract:

The derivatives of boradiazaindacene (BODIPY) are highly fluorescent dyes which have quantum yields near 1.0. These dyes that have exceptional spectral and photophysical stability as compared to other fluorescent groups are used for several different applications. The fluorescent sensor molecules for the detection of cations with PET (photoinduced-electron transfer) mechanism in general have been obtained by the differentiation of the BODIPY core. The extension of conjugation over the pyrrole ring shifts the absorption and emission at longer wavelength. Moreover, it is seen that red emission o

A series of BODIPY dyes have been successfully synthesised and structurally characterised to examine the effect of halogenation at the 2,6-positions and the introduction of styryl and vinylene groups at the 3,5-positions. The photophysical properties were studied, to assess the effect of the enhancement of the rate of intersystem crossing through halogenation on the fluorescence properties and the generation of reactive oxygen species. This is important in the assessment of the suitability of applying these molecules as photosensitizer dyes for photodynamic therapy and photodynamic antimicrobi

Abstract:

Supramolecular chemistry covers intermolecular interactions where non-covalent bonds are involved, and many of them are based on host-guest interactions. Cyclodextrins (CDs) are cyclic oligosaccharides consisting of 6-, 7- or 8-glucose units, which are called alpha-, beta- or gamma-CDs, respectively. They have hydrophobic interior and hydrophilic exterior, and are widely being used as hosts for various organic molecules. The formation of CD inclusion complexes with a variety of dyes has continuously drawn our interests, since CDs are readily available and have ability to include dye molecules

碩士<br>國立中正大學<br>光機電整合工程研究所<br>100<br>This thesis is divided into two parts. In the first part, we used the Z-scan technique with individual 16 picosecond (16 ps) laser pulse to investigate nonlinear refraction properties of (i) six individual transparent liquids (methanol, ethanol, H2O, CS2, toluene and THF) and (ii) two binary transparent liquids (methanol-ethanol and ethanol-CS2). The purpose of this study is to verify whether the interaction between the component liquids renders additional nonlinear refraction behaving as the well characterized Kerr effect. In the second part of this thesis

碩士<br>國立中興大學<br>化學系所<br>103<br>Porphyrins are a group of highly conjugated macrocycle organic compounds. Many porphyrin are naturally occurring, the best-known porphyrins are heme and chlorophyll. Chlorophyll is an extremely important biomolecule, which has high molar extinction coefficient can allow plants to absorb energy from light. In this thesis, we take porphyrin as core of synthesis, and separate two parts to discuss. One is extending the π conjugated – using alkyne substitutes and dimer porphyrin to increase the range of absorption spectrum, expect can enhance the ability of efficiency
