  2. 1. Ruthenium(II) Polypyridyl Complexes : Applications in Artificial Photosynthesis

    Author : Olof Johansson; Licheng Sun; Björn Åkermark; Michael D Ward; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organisk kemi; Chemistry; Kemi;

    Abstract : Molecular mimics of PS II, which consist of a photosensitizer linked to electron acceptors/donors, are attractive candidates for the conversion of solar energy into chemical energy. Several different classes of sensitizers have been studied and among these, ruthenium(II) polypyridyl complexes continue to attract major attention. READ MORE

  4. 2. Molecular Electronic Devices based on Ru(II) Thiophenyl Pyridine and Thienopyridine Architecture

    Author : Robert Steen; Simon Dunne; Sarah Angus-Dunne; Kenneth Wärnmark; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Molecular Electronics; Organic Synthesis; Ruthenium; Pyridyl Complexes; Ligand Design; Fused Ligands; Chemical engineering; Kemiteknik; Biotechnology Chemical Engineering; bioteknik kemiteknik;

    Abstract : According to the famous axiom known as Moore’s Law the number of transistors that can be etched on a given piece of ultra-pure silicon, and therefore the computing power, will double every 18 to 24 months. However, around 2020 hardware manufacturers will have reached the physical limits of silicon. READ MORE

  5. 3. The Synthesis of Molecular Switches Based Upon Ru(II) Polypyridyl Architecture for Electronic Applications

    Author : Robert Steen; Simon Dunne; Jan Bergman; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular Electronics; ruthenium; pyridyl complexes; ligand design; ligand synthesis; Organic chemistry; Organisk kemi; Biotechnology Chemical Engineering; bioteknik kemiteknik;

    Abstract : According to the famous axiom known as Moore’s Law the number of transistors that can be etched on a given piece of silicon, and therefore the computing power, will double every 18 to 24 months. For the last 40 years Moore’s prediction has held true as computers have grown more and more powerful. READ MORE

  6. 4. Design, Synthesis and Properties of Bipyridine-capped Oligothiophenes for Directed Energy and Electron Transfer in Molecular Electronic Applications

    Author : Lasse Nurkkala; Simon Dunne; Sarah Angus-Dunne; Edwin Constable; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Molecular Electronics; Organic Synthesis; Ruthenium; Pyridyl Complexes; Ligand Design; Chemical engineering; Kemiteknik; Biotechnology Chemical Engineering; bioteknik kemiteknik;

    Abstract : The earliest landmark in computer technology was construction of the Electronic Numerial Integrator and Computer, ENIAC. Computational switching was performed with vacuum tubes and relays, rather large in size, making this computer rather unwieldy. READ MORE

  7. 5. Ruthenium(II) Polypyridyl Complexes in Supramolecular Systems relevant to Artificial Photosynthesis

    Author : Henriette Wolpher; Björn Åkermark; Licheng Sun; Johannes Vos; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ruthenium complexes; Organic chemistry; Organisk kemi;

    Abstract : This thesis describes the synthesis and properties of ruthenium complexes relevant to artificial photosynthesis. The work includes preparation of RuIIpolypyridine complexes as well as multi component systems where RuII(bpy)3 or RuII(tpy)2 type complexes are used as photosesnsitizers. READ MORE
