  5. 3. Ground and Excited State Aromaticity : Design Tools for π-Conjugated Functional Molecules and Materials

    Author : Christian Dahlstrand; Henrik Ottosson; Miguel Solà; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fulvene; fulvalene; polyfulvene; aromaticity; triplet state; excited state; Clar structure; polybenzenoid hydrocarbons PBH ; conjugated polymers; computational chemistry; optical spectroscopy; Kemi med inriktning mot organisk kemi; Chemistry with specialization in Organic Chemistry;

    Abstract : The main focus of this thesis is on the aromaticity of the ground state and electronically excited states of π-conjugated molecules and polymers, as well as how aromaticity is connected to their properties.The electronic structures of polybenzenoid hydrocarbons (PBHs) were explored through density functional theory (DFT) calculations and the π-component of the electron localization function (ELFπ).

  6. 4. Dinuclear Manganese Complexes for Artificial Photosynthesis : Synthesis and Properties

    Author : Magnus Anderlund; Björn Åkermark; William H. Armstrong; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Crystal Structure; Artificial photosynthesis; Manganese complex; Organic chemistry; Organisk kemi;

    Abstract : This thesis deals with the synthesis and characterisation of a series of dinuclear manganese complexes. Their ability to donate electrons to photo-generated ruthenium(III) has been investigated in flash photolysis experiments followed by EPR-spectroscopy. READ MORE

  7. 5. Tuning of the Excited State Properties of Ruthenium(II)-Polypyridyl Complexes

    Author : Maria Abrahamsson; Leif Hammarström; Hans-Christian Becker; Russell Schmehl; Uppsala universitet; []
    Keywords : Physical chemistry; Artificial photosynthesis; Ruthenium II ; Bistridentate complexes; Excited state lifetime; Linear donor-photosenstizer-acceptor arrays; Temperature dependence; Excited state decay; Fysikalisk kemi;

    Abstract : Processes where a molecule absorbs visible light and then converts the solar energy into chemical energy are important in many biological systems, such as photosynthesis and also in many technical applications e.g. photovoltaics. READ MORE
