  2. 21. Synthesis of Non-Natural Aromatic Amino Acids Derivatives Solvent-free reactions-Versatile building blocks-Galectin inhibitors

    Author : Erik Tullberg; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organisk kemi; Organic chemistry; Naturvetenskap; Natural science; Multivalent galectin inhibitors; Multifunctional molecules; Amino Acids; Solvent-free reactions;

    Abstract : This thesis deals with three topics concerning the synthesis of non-natural also known as unnatural amino acid derivatives. In the first, solvent-free reaction conditions for the Heck reaction were developed that were superior to previous conditions because the reaction time could be reduced and the work-up procedure simplified.

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; carborane; doxorubicin; 125I; molecular recognition; four-helix bundle; polypeptide conjugate; affinity; chitinase; acetylcholine esterase; Organisk kemi;

    Abstract : This thesis describes the design and synthesis of molecules with potential roles in biomedicine, with an emphasis on molecular recognition in complex biological environments. The first chapter describes the synthesis and evaluation of compounds for use in nuclide therapy. READ MORE

  5. 23. Organic Hole-Transport Materials for Perovskite Solar Cells

    Author : Linqin Wang; Licheng Sun; Nam-Gyu Park; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hole-transport material; Photovoltaic device; Perovskite solar cell; Dopant-free; Carbazole; Spiro[fluorene-9; 9 -xanthene]; Small organic molecule; Crosslinked polymer; Solution-processed.; Kemi; Chemistry;

    Abstract : Research on perovskite solar cells (PSCs) has undergone dramatic development since the first cells were reported in 2009, and the past decade has witnessed a significant breakthrough on their power conversion efficiencies (PCEs) from 3.8% to 25%. READ MORE

  6. 24. Macrocyclic Carbohydrate/Amino Acid Hybrid Molecules - Synthesis and Evaluation as Artificial Receptors

    Author : Johan Billing; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 3-dipolar cycloaddition; 3-triazoles; 2; 1; molecular recognition; artificial receptors; sugar amino acids; cyclic peptides; macrocycles; Organic chemistry; Organisk kemi;

    Abstract : Methods were developed for the synthesis of three different types of macrocyclic carbohydrate/amino acid hybrid molecules. In the synthesis of the first type of macrocycles, a glucosamine derivative was oxidized at C6 and the obtained sugar amino acid was coupled to tripeptides. READ MORE

  7. 25. Organic functionalization of graphene for applications in energy storage devices and optoelectronics

    Author : Cheng Peng; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; graphene; aqueous energy storage; optoelectronics; organic functionalization; 2D materials;

    Abstract : The emergence of one-atom layer thick materials, exemplified by graphene following its first exfoliation by Geim and Novoselov, has sparked significant research interest. Owing to their unique electronic structure, 2D materials are regarded as promising candidates for diverse applications, including field-effect transistors (FETs), solar energy harvesting, biological systems, water purification, and energy storage devices.
