Abstract [en]

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. One oligothiophenein this series was evaluated as a new matrix for MALDI-TOF,with promising results. Another project deals with developmentof oligothiophenes with "in-chain" chirality, which may finduse in polarizing light-emitting diodes.Oligothiophene-porphyrin hybrid materials were synthesized forevaluation as active components in light-producing and/or-harvesting devices. Finally, a novel and simplified synthesisof EDOT, which is a major monomer in oligothiophene chemistry,is presented.
