1. Intramolecular Electronic Interactions in Photon Upconversion and Singlet Fission
Sammanfattning : The sun provides our planet with an abundance of energy in the form of solar light – a continuous stream of photons. Increasing our direct utilization of solar energy will constitute a necessary part in our ongoing replacement of fossil fuels with energy sources free from greenhouse gas emissions. LÄS MER
2. Tailing Charges on New Paths : Ultrafast intramolecular charge transfer in chromophores
Sammanfattning : By tailing charges on their paths within a molecule, one can gain fundamental knowledge of their inherent reactivity. The charges, originally residing in their lowest energy configuration, can upon light absorption move across the system, or transfer in between them. LÄS MER
3. Intramolecular isotope analysis reveals plant ecophysiological signals covering multiple timescales
Sammanfattning : Our societies' wellbeing relies on stable and healthy environments. However, our current lifestyles, growth-oriented economic policies and the population explosion are leading to potentially catastrophic degradation of ecosystems and progressive disruption of food chains. LÄS MER
4. Studies on the intramolecular Claisen condensation and related reactions
Sammanfattning : Intramolecular Claisen or Claisen-like condensations of ß-acetoxy esters, amides or imides to ß-keto-5-lactones are described. Two compounds which can give either this reaction or the analogous reaction to y-lactone prefer to give the latter. LÄS MER
5. Intramolecular electron transfer in DNA and ruthenium(II) systems
Sammanfattning : When ruthenium(II) complexes with heteroaromatic ligands absorb light, an electron is pushed from the metal ion out into one of the ligands, a process called metal-to-ligand-charge-transfer (MLCT). The resulting excited state can be used to initiate further electron transfer processes, or it can decay relatively slow back into the ground state with the emission of light. LÄS MER
