Novel enantiopure bis(pyrrolo)tetrathiafulvalene donors exhibiting chiral crystal packing arrangements [PDF]

, 2009
Two novel enantiopure bis(pyrrolo[3,4-d])tetrathiafulvalene derivatives, substrates for preparing chiral conducting materials, show chiral crystal packing arrangements in which successive layers are rotated in accordance with an exact or approximate 43 ...

Flexible 3D Multi‐Material Printing beyond Layer‐by‐Layer Constraints via Sequential Multi‐Printer Fabrication

Advanced Materials Technologies, EarlyView.
We developed a flexible multi‐material printing strategy that employs sequential printing with different printers. This combined use of printers expands the accessible material scope. Moreover, incorporating Xolography as a sequential step enables support‐free, contactless printing, thereby enhancing structural design flexibility beyond conventional ...

Insights in the antioxidant activity of diarylamines from the 2,3-dimethylbenzo[b]thiophene through the redox profile [PDF]

, 2009
Cyclic voltammetry was used to evaluate the antioxidant activity of 7-aryl or 7-heteroarylamino-2,3-dimethylbenzo[b]thiophenes previously synthesized by some of us, comparing their oxidation potentials with those of the well-known synthetic standards ...

The Uppsala APP Mutation Promotes Wild‐Type Amyloid‐β Aggregation and Deposition In Vivo

Advanced Science, EarlyView.
We investigated in vivo cross‐seeding of amyloid‐β (Aβ) isoforms in transgenic mice co‐expressing wild‐typeAβ and the Uppsala‐mutant Aβ variant (AβUpp), lacking six central residues. Weleveraged MALDI‐MS imaging and hyperspectral microscopy to follow spatio‐temporalAβ deposition.

Beyond Transconductance: Cell‐Polymer Coupling Determines Fidelity in Action Potential Recording via Electrolyte‐Gated Polymer Transistors

Advanced Science, EarlyView.
High electrical performance alone does not guarantee efficient bioelectronic signal transduction. Despite excellent mixed ionic‐electronic conduction, recordings from cardiomyocytes reveal that p(g2T‐TT)‐based OECTs predominantly transduce field potential FP‐like signals due to weak cell‐polymer coupling.

Synthesis of Novel Derivatives of Carbazole-Thiophene, Their Electronic Properties, and Computational Studies

Journal of Chemistry, 2016
A series of carbazole-thiophene dimers, P1–P9, were synthesized using Suzuki-Miyaura and Ullmann coupling reactions. In P1–P9, carbazole-thiophenes were linked at the N-9 position for different core groups via biphenyl, dimethylbiphenyl, and phenyl ...

Oligomers of thieno[3,4-c]pyrrole-4,6-dione: Raman spectra [PDF]

, 2017
Oligothiophenes are π-conjugated compounds made by concatenation of thiophenes. [1] Due to the low aromaticity of thiophene, inter-ring π-electron delocalization is favored which has strong implication in their electro-optical properties and in their ...

A Reliable Strategy to Unravel the Structure and Composition of Semiconducting Conjugated Donor‐Acceptor Block Copolymers

Advanced Science, EarlyView.
This work proposes a reliable strategy to elucidate the structure and composition of conjugated donor‐acceptor block copolymers. The method, based on NMR analysis, allows to extract key structural information such as the number of heterojunctions (NoH) and the number of blocks (NoB) of the copolymers.

Dual Covalent Targeting of STING Cysteines 292/309 Disrupts Functional Oligomerization and Enables Potent Antagonist Development

Advanced Science, EarlyView.
We report a rational design strategy for STING antagonists by dual covalent targeting of Cys292/309 in its C‐terminal domain, directly preventing functional oligomerization. Through covalent warhead repurposing, we identified P005091 and revealed its unique dual‐cysteine mechanism.

One-pot sequential synthesis of tetrasubstituted thiophenes via sulfur ylide-like intermediates

Beilstein Journal of Organic Chemistry, 2018
Herein, we describe a novel approach for the practical synthesis of tetrasubstituted thiophenes 8. The developed method was particularly used for the facile preparation of thienyl heterocycles 8.
