1. 1. Chiral Liquid Crystalline Side-Chain Polymers. Design, Synthesis and Properties

   Författare :Magnus Svensson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lateral substituent; electro-optic; ferroelectric; molar mass; polymer; side-group; thin film; polysiloxane;

   Sammanfattning : The potential use of chiral liquid crystalline materials, low molar mass as well as polymers, in technical applications has been recognized for some decades now. A number of interesting phenomena based on the spontaneous ordering of the liquid crystal forming molecules are strong reasons for the research effort in this area. LÄS MER

3. 2. Dyes and their adsorption onto nanocrystalline TiO2 electrodes : Synthesis, characterisation and applications

   Författare :Viviane Aranyos; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Chemistry; Kemi; organisk kemi; Organic Chemistry;

   Sammanfattning : The syntheses of two type of dyes (phthalocyanine and ruthenium tris-bipyridyl) are presented here. Their characterisation involves the use of cyclic voltammetry, NMR- and UV-visible spectroscopy. Once adsorbed on nanocrystalline TiO2 electrodes, their electrochemical, spectroelectrochemical and photoelectrochemical properties were investigated. LÄS MER
