  2. 1. N-Heterocyclic Carbene Catalysis in Organic Synthesis - A Green Chemistry Approach

    Author : Linda Ta; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; aerobic oxidation; ionic liquid; sustainability; NHC catalysis; oxidative NHC catalysis; green chemistry; OTHO; Organocatalysis;

    Abstract : The twelve principles of green chemistry were created as a response to the multiple environmental issues caused by the release of waste from the chemical industry. The principles acts as a guide in the development of sustainable chemical processes for the syntheses of important molecules needed to sustain our living standards. READ MORE

    Abstract : The call for more sustainable processes in the chemical society has led to the development of the field of green chemistry. The Twelve Principles of Green Chemistry serve as guidelines for the design of processes. READ MORE

  5. 3. Structure-Property Relationships in Chromophore-Organogel Assemblies: Consequences for Triplet-Triplet Annihilation and Singlet Fission

    Author : Deise Fernanda Barbosa de Mattos; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; photophysics; singlet fission; triplet-triplet annihilation upconversion; self-assembly; organogel.;

    Abstract : Better utilization of the solar spectrum by absorbing photons that are currently wasted by solar cells, due to the bandgap mismatch with the semiconductor, will help to improve the device efficiency. Two low energy photons can be upconverted to one high energy photon through triplet-triplet annihilation (TTA-UC); one high energy photon can be down converted to form two charge carriers through singlet fission (SF).
