  1. 1. Application of the 2-Pyridone Hydrogen-Bonding Motif in Supramolecular Catalysis and in Phenanthroline Based Ligands

    Författare :Stefan Jonsson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; X-ray crystallography; Phenanthroline; Supramolecular Catalysis; Jacobsen-Katsuki Epoxidation; Mn salen ; Hydrogen-bonding; Supramolecular Chemistry; 2-Pyridone; Organisk kemi;

    Sammanfattning : This thesis concentrates on the development, synthesis and evaluation of supramolecular systems, assembled from its components by means of hydrogen bonding, using the self-complementary 2-pyridone motif. The thesis is divided in two parts. LÄS MER

  3. 2. DNA Interactions with Chiral Polyaza-aromatic Ruthenium(II) Complexes

    Författare :Per Lincoln; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phenanthroline; binding geometry; binding isotherm; DNA; dppz; linear dichroism; intercalation; ruthenium; cooperative binding;

    Sammanfattning : The binding to DNA of a series of chiral ruthenium complexes is studied with optical spectroscopy techniques, including isotropic absorption, linear dichroism (LD) and emission anisotropy as well as steady-state and time-resolved luminescence. The thesis focuses on the ìlight-switchî complex [Ru(phen)2dppz]2+ which binds to DNA by intercalation and luminesces when bound to DNA but not in pure buffer solution (phen=1,10-phenanthroline; dppz=dipyrido[3,2-a:2',3'-c]phenazine).

  5. 4. Iron nutrition dynamics - Differences between calcicole and calcifuge plants

    Författare :Angelika Zohlen; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 10-phenanthroline; 1; chlorophyll; plaque; root; leaf; immobilization; plants; calcifuge; Iron; calcicole; Plant ecology; Växtekologi;

    Sammanfattning : One third of the earth´s soils is calcareous. Calcifuge plants are excluded from these soils, and one of the main causes is Fe deficiency, as Fe solubility in calcareous soil is very low. A lack of Fe lowers chlorophyll content, visible as yellowing of leaves, called chlorosis. LÄS MER

  7. 5. Controlling function by structure-intermolecular interactions and crystal engineering with N-donor ligands

    Författare :Mohamed I D M Ghazzali; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; OPL; 10 phenanthroline]2 .; single crystal diffraction; intermolecular interactions; crystal engineering; Fe II coordination polymers; Schiff’s bases; porphyrins; intercalation; [ Ru tris-1;

    Sammanfattning : In the solid state regime, crystal engineering based on non-covalent synthesis requires an intuition about the intermolecular forces that can dictate the molecular architecture. Hydrogen bonds have become an instrumental tool in the self assembly and supramolecular chemistry. LÄS MER
