  1. 1. Synthesis of Electroactive Molecules Based on Benzodioxins and Tetrathiafulvalenes

    Författare :Emma Dahlstedt; KTH; []
    Nyckelord :Synthesis; Benzodioxin; Tetrathiafulvalene; Mesoion; Organic Conductor; Cation Radical Salt; Cyclic Voltammetry; Electrocrystallization; Self-Assembly Monolayer; SAM; Organic Field-Effect Transistor; OFET;

    Sammanfattning : This thesis deals with the synthesis of electroactiveorganic compounds. The synthesis of ethylenedioxy-benzodioxinstri-dioxin and tetra-dioxin are described. These molecules wereprepared with the aim of creating donor molecules for cationicradical salts. LÄS MER

  3. 2. Electrolyte-Based Organic Electronic Devices

    Författare :Elias Said; Magnus Berggren; Robert Forchheimer; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Conjugated polymers; Electrolytes; Organic Field Effect Transistors; Physics; Fysik;

    Sammanfattning : The discovery of semi-conducting and conducting organic materials has opened new possibilities for electronic devices and systems. Applications, previously unattainable for conventional electronics, have become possible thanks to the development of conjugated polymers. LÄS MER

  4. 3. XPS studies of an organic anode and hole-conductor system : PEDOT-PSS

    Författare :Stina Karin Maria Jönsson; Magnus Boman; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis deals with photoelectron spectroscopy of conducting polymer systems. A particular system, poly(3,4-ethylenedioxythiophene)­ polystyrenesulfonic acid (PEDOT-PSS), has been the main focus of this work. It is an aqueous colloidal dispersion consisting of doped conjugated polymer PEDOT with counter ions provided by the PSS chains. LÄS MER

  5. 4. Characterisation of Organic Dyes for Solid State Dye-Sensitized Solar Cells

    Författare :Ute Cappel; Anders Hagfeldt; Gerrit Boschloo; Udo Bach; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; energy alignment; hole conductor; injection; interface; perylene; photo-induced absorption; regeneration; spectroelectrochemistry; spiro-MeOTAD; Stark effect; titanium dioxide; Physical chemistry; Fysikalisk kemi; Physical Chemistry; Fysikalisk kemi;

    Sammanfattning : Energy from the sun can be converted to low cost electricity using dye-sensitized solar cells (DSCs). Dye molecules adsorbed to the surface of mesoporous TiO2 absorb light and inject electrons into the semiconductor. LÄS MER

  7. 5. Studies of The Electronic Structure of CuPc and PTCDA - Two Molecular Organic Semiconductors

    Författare :Maria Nilsson Tengelin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PTCDA; ITO; UPS; Organic Semiconductor; XPS; CuPc;

    Sammanfattning : Since the discovery of organic materials with conducting and semiconducting proper¬ties a few decades ago, the research in this field has intensified and has become in¬creasingly important. Expected advantages of both economical and technological nature have been powerful driving forces in this development, and today organic based devices are becoming a reality for commercial applications.
