  1. 1. Synthesis of Organo-Iron(II) Complexes Including N-Heterocyclic Carbene Ligation as Solar Cell Material.

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Salim Charkas; [2023]
    Keywords : Dye-sensitized solar cell; Transition metal complex; Synthesis iron; N-heterocyclic carbene NHC ; Organic chemistry; Chemistry;

    Abstract : The push-pull design has been shown to increase DSC performance through the introduction of electron-withdrawing groups and electron-donating groups, usually on opposite far ends of the sensitizer. The scope of this thesis was to synthesize several pre-N-heterocyclic carbene ligand analogs that are inspired by the push-pull design in an attempt to investigate their susceptibility to Fe(II) complexation.

  3. 2. Influence of The Heavy Atom Effect on The Cage Escape Yields of Iron(III)-Photosensitizers with N-Heterocyclic Carbene Ligands

    University essay from Uppsala universitet/Fysikalisk kemi

    Author : Johannes Wega; [2022]
    Keywords : ;

    Abstract : The recent emergence of earth-abundant iron(III)-photosensitizers with N-heterocyclic carbene ligands, exhibiting nanosecond ligand-to-metal charge-transfer states with suitable redox potentials to activate a broad range of substances, offers the possibility to convert sunlight into chemical substances, such as fuels or pharmaceuticals, in an environmentally friendly way. These complexes, however, often suffer from low yields of charge-separated products escaping the solvent cage, making such applications inherently inefficient. READ MORE

  4. 3. P-cycling in sub-Arctic lakes – the importance of sediment release and retention

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Hanna Ravry; [2022]
    Keywords : phosphorus; sediment; oligotrophication;

    Abstract : Oligotrophication is generally caused by a decreased nutrient availability, usually due to phosphorous limitation. This is a phenomenon impacting the entire food web and at worst causing cascading alterations within an ecosystem. Lakes of the Northern Hemisphere have lately been documented to be subjected to oligotrophication (e.g. READ MORE

  5. 4. Synthesis and characterization of half-sandwich complexes with salicylaldimine ligand derivatives

    University essay from Lunds universitet/Kemiska institutionen

    Author : Ujala Mahmud; [2021]
    Keywords : Malaria; Plasmodium; Ruthenium; Iridium; Rhodium; Inorganic chemistry; Chemistry;

    Abstract : New half-sandwich complexes of pentamethylcyclopentadienyl-rhodium, iridium, and p-cymene-ruthenium have been synthesized and characterized. All metal complexes contain ligands based on a 4-chloroquinoline framework analogous to the antimalarial drug chloroquine. READ MORE

  6. 5. Photochemistry of Copper Coordination Complexes

    University essay from KTH/Kemiteknik

    Author : Amanda Blad; Helena Glisén; Filippa Ludvig; [2021]
    Keywords : Copper Halide Organic Complex; Time-Resolved Photoluminescence; Metal-organic Framework; Coordination Polymer; Thin Film Solar Cell; Koppar halid organiska komplex; tidsberoende fotoluminesens; metallorganiska ramverk; koordinationspolymer; tunnfilmssolcell.;

    Abstract : The United Nations have set a number of sustainability goals, Agenda 2030, in order to combat the worlds largest challenges and injustices. The energy market is one of these urgent issues which must be solved. Solar energy is expected to be the fastest growing energy source in the future energy mix. READ MORE
