  4. 2. Unconventional Modulation of Diarylethene Photoswitches

    Author : Wera Larsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; photochromic molecules; photochemistry; photon upconversion; molecular photoswitches; triplet-triplet annihilation; diarylethene; nanocrystals; triplet sensitization;

    Abstract : Light can be manipulated and modulated to fit a particular need or application, such as overcoming a spectral mismatch when facilitating a high energy photochemical reaction. This can be of use in various applications, including solar energy conversion and biological contexts. READ MORE

  5. 3. Light-Induced Routes to Sustainable Biocrudes for Fuels and Lubricant Oils

    Author : Leandro Cid Gomes; Henrik Ottosson; Norbert Hoffmann; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Aviation fuels; triplet sensitization; photoacid; renewable energy; photochemistry; Kemi; Chemistry;

    Abstract : Fossil-based hydrocarbons are at present the ideal compounds for jet fuels and lubricant oils, so their replacement by novel technologies is not easy. Instead, sustainable routes to hydrocarbons, such as sunlight-driven processes, are desired to reduce the environmental impact by the transport sector. READ MORE

  6. 4. Organic Photochemistry. Scope and Limitations of Twofold Adiabatic Cis-Trans Isomerizations

    Author : Ingjald Anger; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : To investigate the scope and limitations of twofold adiabatic cis/trans photoisomerizations, a number of bis-stilbenes and bisstyryl compounds have been prepared and studied in the excited singlet or triplet states. Their structures vary according to the size of the .pi. READ MORE
