Development of Au(I) Cycloadditions, Trifluoromethylation and Novel Au(I) Complexes
Siah, Huey-San Melanie (Doctoral theses at NTNU;2020:167, Doctoral thesis, 2020)The field of gold(I)-catalysed reactions in organic chemistry has been expanding rapidly in the last two decades. Gold catalyses a diverse range of transformations and is especially useful in the activation of triple bonds ... -
Effect of seven different terthiophene π-spacers on dye performance in dye-sensitized solar cells
Almenningen, David Moe; Hansen, Henrik Erring; Buene, Audun Formo; Hoff, Bård Helge; Gautun, Odd Reidar (Journal article; Peer reviewed, 2022)To ensure high photocurrents from dye-sensitized solar cells (DSSC), it is important that the dye absorbs as much of the energy from the sunlight as possible. To achieve a wide absorption and cover larger parts of the solar ... -
