Livia Civitelli, Linnea Sandin, Erin Nelson, Sikander Iqbal Khattak, Ann-Christin Brorsson and Katarina Kågedal, The Luminescent Oligothiophene p-FTAA Converts Toxic A beta(142) Species into Nontoxic Amyloid Fibers with Altered Properties, 2016, Journal of Biological Chemistry, (291), 17, 9233-9243. http://dx.doi.org/10.1074/jbc.M115.696229 Copyright: American Society for Biochemistry and Molec...
A structure-property study across a series of donor-acceptor-donor structures composed of mono- and bi-(1,3,4-oxadiazole) units symmetrically substituted with alkyl functionalized bi-, ter- and quaterthiophene segments is presented. Synthetically tailoring the ratio of electron-withdrawing 1,3,4-oxadiazole to electron-releasing thiophene units and their alkyl grafting pattern permitted us to sc...
Improvements in the performance of small molecule-based organic solar cells have been reported through the use of a cyanopyridone acceptor group. This acceptor fragment enhances the absorbance of an oligothiophene-based dye and enables the addition of a solubilising alkyl chain that facilitates simple device fabrication from solution.
A simple and versatile solution-processing method based on molecular self-assembly is used to fabricate organic single crystal microwires of a low bandgap quinoidal oligothiophene derivative. Individual single crystal microwire transistors present well-balanced ambipolar behaviour with hole and electron mobilities as high as 0.4 and 0.5 cm(2) V(-1) s(-1), respectively.
Directional growth of π-basic oligothiophene stacks on solid substrates is achieved by self-organizing, surface-initiated disulfide exchange polymerization. Successful addition of co-axial π-acidic stacks by templated hydrazone exchange provides general access to multicomponent architectures of unique complexity.
Symmetric oligothiophene derivatives containing hydrogen bond forming segments create self-supporting organogels consisting of self-assembled 1D nanostructures at low concentrations. Hydrogen bond formation and π-π stacking were both found to be crucial for the formation of conductive supramolecular networks of 1D nanostructures.
An oligothiophene derivative named DR3TBDTT with high hydrophobicity was synthesized and functioned as the hole transporting material without an ion additive. 8.8% of power conversion efficiency was obtained for CH3NH3PbI3-xClx based planar solar cells with improved stability, compared to devices using Li-TFSI doped spiro-MeOTAD.
