1. Synthesis and conformational analysis of amino-substituted alicyclic derivatives of 5H-dibenzo[a,d]cycloheptene and diphenylmethane : new uptake inhibitors of noradrenaline as potential antidepressants
Sammanfattning : .... LÄS MER
2. Design and development of electro-responsive [8]annulene switches
Sammanfattning : This thesis describes studies regarding the design, synthesis, and analysis of new types of electro-responsive [8]annulene-based switches.A starting material for the targeted material is dibenzo[a,e]cyclooctatetraene (dbCOT). LÄS MER
3. Methods for Determination of Benzo(a)pyrene and High Molecular Weight (>300 Da) Polycyclic Aromatic Hydrocarbons in Particulate Matter from Ambient Air and Vehicle Exhausts
Sammanfattning : Air pollution with particulate matter (PM) raises considerable concern because of its adverse effects on human health. For this reason, and because the mechanisms of PM toxicity are not fully known, there is an urgent need to determine the chemical constituents of atmospheric PM, especially PM emanating from traffic - a major source of urban PM.

4. Investigations of New Biomimetic Transamination Systems and Inclusion Complexation with Cyclodextrins
Sammanfattning : Two new transamination systems are described. The first example is a dibenzo[a,d]- cycloheptene containing system, designed to accomplish a [1,3]-hydride transfer. Several catalysts have been examined for this purpose. tris-Pentafluorophenyl borane was found to be the most efficient catalyst. LÄS MER
5. Factors Influencing the Yield of Mutations Induced by Polycyclic Aromatic Hydrocarbons in Mammalian Cells
Sammanfattning : Environmental contaminants are ubiquitously present in the urban environment, this has the implication that humans are exposed to toxic and carcinogenic chemicals. Polycyclic aromatic hydrocarbons (PAH) are one type of environmental contaminants, which are produced by combustion of organic compounds. LÄS MER
