   Författare :Lisa de Groot; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photoredox catalysis; iron N-heterocyclic carbene complexes; Fe-NHC; Visible light; ATRA; BHAS;

   Sammanfattning : Photoredox catalysis is a rapidly expanding field, in which organic transformations are catalysed using light. The most commonly used photoredox catalysts (PCs) are transition metal complexes which absorb in the visible region of the electromagnetic spectrum. LÄS MER

3. 2. Structure-Property Relationships of Iron N-Heterocyclic Carbene Complexes : Synthesis, Characterization and Application

   Författare :Valtýr Freyr Hlynsson; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; photoredox catalysis; photovoltaics; photosensitizer; N-heterocyclic carbene NHC ; BHAS; synthesis; Organometallic chemistry; structure-property relationship; coordination chemistry; heteroleptic iron complexes; geometry; photophysics;

   Sammanfattning : Resulting from the general availability of first-row transition metals, compared to their second- and third-row counterparts, photosensitizers (PSs) based on metals like iron have gained interest as candidates to enable photochemistry from solar energy, a largely underutilized energy source. Iron complexes equivalent to other metal complexes, currently being used as PS, do lack some of the advantageous properties required to challenge the established PSs. LÄS MER
