  2. 1. Synthesis and development of compounds for nonlinear absorption of light

    Author : Tomas Kindahl; Bertil Eliasson; Sascha Ott; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Platinum acetylide; nonlinear absorption; optical power limiting; oxazole; quantum chemistry calculation; quantum chemical calculation; triplet absorption; organisk kemi; Organic Chemistry; fysikalisk kemi; Physical Chemistry; Quantum Chemistry; kvantkemi;

    Abstract : High-intensity light — for instance that from a laser — can be destructive, not only to the human eye, but also to equipment such as imaging sensors and optical communication devices. Therefore, effective protection against such light is desirable. READ MORE

  5. 3. Applications of Chromophores and Multiphoton Techniques to Study Structure and Interactions of Bio-macromolecules in Assembled State

    Author : Piotr Hanczyc; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Z-scan; One-photon spectroscopy; oxazole yellow dyes; two-photon absorption.; non-linear spectroscopy; PVA DNA dyes films; linear dichroism; ruthenium complexes;

    Abstract : The research presented in this thesis is concerned with the linear and nonlinear optical properties of biopolymers and the chromophores that bind to them. This thesis combines analyses of the interactions of biomolecules with technological improvements of already existing systems for bionanotechnology-related research. READ MORE

  6. 4. Transition-Metal Catalyzed Synthesis of Small- and Medium-Sized Rings Applications toward oxazole synthesis, cycloheptadienes, and natural products

    Author : Henrik von Wachenfeldt; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; catalysis; transition metal; cyclization; cycloaddition; natural product;

    Abstract : This thesis deals with the development of novel methodologies for the synthesis of hetero- and carbocycles enabled by transition metal catalysis. The second chapter of the thesis describes a gold-catalyzed three-component reaction to form a variety of substituted oxazoles from readily available N-benzylimines, terminal alkynes, and acyl chlorides.

  7. 5. Rearrangements to vinyl substituted hetero- and carbocycles : Total synthesis of siphonazole B and otherapplications in oxazole and saturated ringsynthesis

    Author : Filip Paulsen; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The aim of this thesis is to explore and develop new reactions for rapid generation of molecular complexity. Byenabling access to important molecules in a less wasteful and more cost-efficient manner such developmentbenefits the whole modern society, where increasingly complex molecules are needed to solve problems withinfields ranging from medicine, to materials sciences and the perfume industry.
