Conducting copolymers of thiophene functionalized polystyrenes with thiophene

Journal of Electroanalytical Chemistry, 2005
Abstract Thiophene capped polystyrenes (TCP1, TCP2) were synthesized by atom transfer radical polymerization of styrene followed by Suzuki condensation with 2-thiophene boronic acid. Electrically conducting graft polymers of TCP1 and TCP2 with thiophene were achieved by electrochemical methods. Characterization of the graft polymers were performed by

Selenophene π‐Bridge Enables Balanced Ambipolar Transport in High‐Performance Organic Electrochemical Transistors

Advanced Science, EarlyView.
We synthesized a high‐performance balanced ambipolar OECT polymer, P(gTDPPSe), via selenophene π‐bridge engineering. The selenophene π‐bridge enhances backbone planarity and optimizes the energy levels for doping, enabling high and balanced p/n‐type transconductance‐a key factor for high‐gain complementary inverters.

Regioselective C–H Activation of Substituted Thiophenes

, 2017
Die C–C-Bindungsknüpfung an Thiophenen wurde mittels Pd-katalysierter C–H-Aktivierung eingehend untersucht. Unter anderem gelang die direkte C4-selektive Arylierung mono- und disubstituierter Thiophene mit Organobor-Verbindungen in hohen Ausbeuten und ...

Solution‐Shearing of Highly Smooth Ion‐Gel Thin Films: Facilitating the Deposition of Organic Semiconductors for Ion‐Gated Organic Field Effect Transistors

Advanced Electronic Materials, Volume 11, Issue 6, May 2025.
A straightforward method is introduced to produce ion‐gel films with very low surface roughness by employing a solution‐shearing coating process. These ion‐gel films permit the growth of crystalline thin films of various small molecule organic semiconductor molecules directly on top of the ion‐gel layer, thereby enabling “inverted” small molecule ...

Thermoelectric Properties of a Diketopyrrolopyrrole Polymer With Radical Pending Units

Advanced Electronic Materials, EarlyView.
The successful incorporation of TEMPO radicals as side‐chain groups onto the conjugated backbone of an n‐type polymer significantly enhanced the doping efficiency of N‐DMBI via a hydrogen transfer doping mechanism. ABSTRACT Organic n‐type polymers usually suffer from relatively low electrical conductivity which hampers their application as an active ...

Intramolecular (4+3) Cycloadditions of Thiophenes

, 2019
In contrast to the rich (4+3) cycloaddition chemistry of furans [1], only one instance of an intermolecular (4+3) cycloaddition of a thiophene has appeared with an unreported yield [2].

All‐Solution‐Processed Perovskite Light‐Emitting Transistors Enabled by a Fully Organic Architecture

Advanced Electronic Materials, EarlyView.
Fully solution‐processed light‐emitting transistors based on CsPbBr3 perovskite nanocrystals (Pe‐LETs) are demonstrated using an all‐organic platform. By optimizing film formation and device integration, the Pe‐LETs achieve bright green emission with excellent color purity and a peak external quantum efficiency of 4.17 × 10−3 %, marking a step forward ...
