  1. 1. Heterometallic Oxo-Alkoxides of Europium, Titanium and Potassium

    University dissertation from Uppsala : Uppsala universitet, Institutionen för materialkemi

    Author : Erik Berger; Uppsala universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Alkoxides; Europium; Lanthanoids; Electronic absorption spectroscopy; f-f spectroscopy; NATURAL SCIENCES Chemistry Inorganic chemistry Coordination chemistry; NATURVETENSKAP Kemi Oorganisk kemi Koordinationskemi; Inorganic Chemistry; Oorganisk kemi;

    Abstract : Coordination compounds of europium and titanium with oxide, ethoxide (OCH2CH3), iso-propoxide (OCH(CH3)2) and tert-butoxide (OC(CH3)3) ligands have been studied. These belong to the general class of oxo-alkoxides, MxOy(OR)z, with alkoxide ligands (OR) containing an organic, aliphatic part R. READ MORE

  3. 3. Synthesis and characterisation of heterobimetallic erbium alkoxides

    University dissertation from Stockholm : Department of Inorganic Chemistry, Stockholm University

    Author : Maria Wijk; Stockholms universitet.; [1997]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Chemistry Inorganic chemistry; NATURVETENSKAP Kemi Oorganisk kemi; oorganisk kemi; Inorganic Chemistry;

    Abstract : This thesis describes the synthesis and characterisation of alkoxides in the Er-M systems, where M = Al, Ti and Zr. The compounds found have been characterised by IR, UV-Vis DSC and single-crystal X-ray diffraction techniques and by chemical behaviour. READ MORE

  4. 4. X-ray structural studies of lanthanide alkoxides

    University dissertation from Stockholm : Department of Physical, Inorganic and Structural Chemistry, Stockholm University

    Author : Marat Moustiakimov; Stockholms universitet.; Stockholms universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; strukturkemi; Structural Chemistry;

    Abstract : A number of homo- and hetero-metallic lanthanide (oxo-)isopropoxides with the general composition LnxMyO(OiPr)p(HOiPr)q has been structurally characterized by means of single crystal X-ray diffraction. The studied compounds may be divided into five groups by the geometry of their metal-oxygen core. READ MORE

  5. 5. Novel Possibilities for Advanced Molecular Structure Design for Polymers and Networks

    University dissertation from Stockholm : KTH

    Author : Anna Finne; KTH.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ring-opening polymerization; coordination-insertion; germanium; cyclic tin alkoxides; spirocyclic initiators; poly L-lactide ; poly 1; 5-dioxepan-2-one ; triblock; star-shaped; network; functionalization; morphology; AFM; NATURAL SCIENCES Chemistry Organic chemistry Polymer chemistry; NATURVETENSKAP Kemi Organisk kemi Polymerkemi;

    Abstract : Synthetic and degradable polymers are an attractive choicein many areas, since it is possible to control the way in whichthey are manufactured; more specifically, pathways tomanipulate the architecture, the mechanical properties and thedegradation times have been identified. In this work,L-lactide, 1,5-dioxepan-2-one and ε-caprolactone were usedas monomers to synthesize polymers with different architecturesby ring-opening polymerization. READ MORE
