    Sammanfattning : This thesis deals with the development of complexes that are active catalysts for H2O oxidation. Promoting proton-coupled electron transfer has been a highly important feature in the development of these catalysts. LÄS MER

  3. 2. Synthesis and Evaluation of Photoactive Pyridine Complexes for Electron Transfer Studies and Photoelectrochemical Applications

    Författare :Judit Modin; Helena Grennberg; Leif Hammarström; Jean-François Nierengarten; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Fullerene; solar cell; bipyridines; Ruthenium; organic synthesis; Organisk kemi; Organic chemistry; Organisk kemi;

    Sammanfattning : In this thesis, the preparation of new photoactive substances containing mono- and bipyridines coordinated to ruthenium is presented together with initial evaluations of their photoelectrochemical and photophysical properties. Complexes of the type Ru(bpy)2(4-X-py)2 (X = SH, COOH) were prepared and used in Grätzel-type solar cells based on ZnO. LÄS MER
