Morphology and structure of organic thin films for solar cells and transistors application
We report on the synthesis of two new conjugated block-oligomers based on vinylene. phenylene and bithiophene units. Depending on the chemical assemblage of units. the optical and semiconducting properties are increased or on the contrary decreased as compared to the quaterthiophene (4T). FETs characteristics as well as thin film morphology of the more conjugated block-oligomer were investigated.
