  1. 26. Novel Organophosphorus Compounds for Materials and Organic Synthesis

    Författare :Keyhan Esfandiarfard; Sascha Ott; Declan Gilheany; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis is devoted to the development of new organophosphorus compounds for potential uses in material science and as reagents in Organic Chemistry. Organophosphorus compounds in a single molecule or organic electronics context are appealing as the phosphorous centers perturb the electronic properties of the π-conjugated systems while at the same time provide synthetic handles for subsequent synthetic modifications.

  2. 27. Structure and morphology control of organic semiconductors for functional optoelectronic applications

    Författare :Jenny Enevold; Ludvig Edman; Thomas Wågberg; Christian Müller; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Organic electronics; organic photonics; patterning; fullerene; polymerization; dimerization; spray-deposition; morphology; small molecule donor; high open-circuit voltage;

    Sammanfattning : The functionality and application of organic semiconductors are largely dependent on their constituent structure and morphology. This thesis presents a number of functional and novel approaches for the control and tuning of structural and morphological features of a variety of organic semiconductor materials, and also demonstrates that these approaches can be utilized for improved device operation of field-effect transistors, organic solar cells and light-emitting electrochemical cells.

  3. 28. Diaryliodonium Salts : Synthesis, Applications and Computational Investigations

    Författare :Marcus Reitti; Berit Olofsson; Michael Greaney; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diaryliodonium salt; hypervalent iodine; density functional theory; aryne; phenol; nitroarene; organisk kemi; Organic Chemistry;

    Sammanfattning : Organic chemists have the ability to create complex organic molecules by connecting molecular building blocks in different ways. To name a few, these molecules are used as medicines, pesticides or in our household electronics, and are therefore crucial to life as we know it. LÄS MER

  4. 29. Novel Approaches to Phosphorus-containing Heterocycles and Cumulenes

    Författare :Anna Arkhypchuk; Sascha Ott; John D. Protasiewicz; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phosphorus; phosphole; oxaphosphole; cumulene; phospha-Wittig-Horner reagent; molecular electronics; Chemistry; Kemi;

    Sammanfattning : Fast development in all areas of life and science over the last 50 years demands versatile, energy efficient and cheap materials with specific but easily tuneable properties which can be used for example in organic light emitting diodes (OLEDs), thin-film transistors, photovoltaic cells, etc. This thesis is devoted to the development of novel synthetic approaches to molecules with potential applications in the field of molecular electronics.
