Air-stable solution-processed ambipolar organic field-effect transistors based on a dicyanomethylene-substituted terheteroquinoid derivative.
Dicyanomethylene-substituted quinoidal mixed oligomer was synthesized as a new soluble organic semiconductor, and OFET devices fabricated with a spin-coated thin film of showed ambipolar FET characteristics with electron and hole mobilities of 1.6 x 10(-2) and 7.0 x 10(-3) cm(2) V(-1) s(-1), respectively.
متن کاملAir-Stable n-channel Diketopyrrolopyrrole-Diketopyrrolopyrrole Oligomers for High Performance Ambipolar Organic Transistors.
n-channel organic semiconductors are prone to oxidation upon exposed to ambient conditions. Herein, we report design and synthesis of diketopyrrolopyrrole (DPP)-based oligomers for ambipolar organic thin-film transistors (OFETs) with excellent air and bias stability at ambient conditions. The cyclic voltammetry measurements reveal exceptional electrochemical stability during the redox cycle of ...
متن کاملAir-stable, high-performance organic n-channel transistors
Organic thin-film transistors (TFTs) are of interest for flexible, large-area electronics applications, such as rollable or foldable information displays, conformable sensor arrays, and plastic circuits [1]. The vast majority of the organic TFTs that have been developed to date are p-channel TFTs, meaning that the electric currents in these transistors are due to the flow of positive charge car...
متن کاملBPTs: thiophene-flanked benzodipyrrolidone conjugated polymers for ambipolar organic transistors.
A series of novel thiophene-flanked benzodipyrrolidone (BPT)-based alternating copolymers are synthesised, their optical and electrical properties evaluated. The BPT unit promotes a conjugated, planar polymer backbone, with a low bandgap, primarily due to low lying LUMO energy levels. Copolymerisation with thiophene exhibits well balanced ambipolar organic field-effect transistor performance, w...
متن کاملStable organic thin-film transistors
Organic thin-film transistors (OTFTs) can be fabricated at moderate temperatures and through cost-effective solution-based processes on a wide range of low-cost flexible and deformable substrates. Although the charge mobility of state-of-the-art OTFTs is superior to that of amorphous silicon and approaches that of amorphous oxide thin-film transistors (TFTs), their operational stability general...
