2. 1. NEW OLIGOTHIOPHENES

   Author : Fredrik von Kieseritzky; KTH; []
   Keywords : oligothiophenes; synthesis; light-emitting diodes; field-effect transistors; photoluminescence; quantum efficiency;

   Abstract : This thesis deals with synthesis and characterization of newoligothiophenes and derivatives thereof, for use as organicsemiconductors in optical and electronic applications, such asfield-effect transistors and light-emitting diodes. Much workis devoted to the development of new synthetic strategies forinteresting building blocks, to beused for synthesizing suchmaterials. READ MORE

4. 2. New Oligothiophenes

   Author : Fredrik von Kieseritzky; KTH; []
   Keywords : ;

   Abstract : This thesis deals with synthesis and characterization of newoligothiophenes and derivatives thereof, for use insemiconductor applications. One series of regiodefinedoligothiophenes up to the octamer was prepared and evaluated.Photoluminescence quantum efficiencies in solution were 22-31%, but dropped to 2-5 % in the solid state.
