1. NEW OLIGOTHIOPHENES
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

2. New Oligothiophenes
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.

3. Anionic oligothiophenes : Optical tools for multimodal fluorescent assignment of protein aggregates
Abstract : Luminescent conjugated oligothiophenes (LCOs) represent a useful and interesting class of materials well known for their abilities as transducers for colorimetric and fluorometric reporting. Specifically, they have the ability to produce a conformation-dependent spectral signature reflective of changes in their local environment. READ MORE

4. Asymmetric Oligothiophenes : Chemical Evolution of Multimodal Amyloid Ligands
Abstract : Luminescent conjugated polymers (LCPs) and luminescent conjugated oligothiophenes (LCOs) can be used as molecular probes to study diseases associated with protein aggregation. The conventionally used dyes to study and detect protein aggregates, denoted amyloid, have been Congo red (CR) and Thioflavin T (ThT). READ MORE

5. Poly-and oligothiophenes : Optical probes for multimodal fluorescent assessment of biological processes
Abstract : One interesting class of molecules in the research field of imaging biological processes is luminescent conjugated polythiophenes, LCPs. These fluorescent probes have a flexible backbone consisting of repetitive thiophene units. READ MORE
