Conducting polymers (CPs), thanks to their unique properties, structures made on-demand, new composite mixtures, and possibility of deposit on a surface by chemical, physical, or electrochemical methodologies, have shown in the last years a renaissance and have been widely used in important fields of chemistry and materials science. Due to the extent of the literature on CPs, this review, after a concise introduction about the interrelationship between electrochemistry and conducting polymers, is focused exclusively on the following applications: energy (energy storage devices and solar cells), use in environmental remediation (anion and cation trapping, electrocatalytic reduction/oxidation of pollutants on CP based electrodes, and adsorption of pollutants) and finally electroanalysis as chemical sensors in solution, gas phase, and chiral molecules. This review is expected to be comprehensive, authoritative, and useful to the chemical community interested in CPs and their applications.

<p>A source-degenerated Schmitt-trigger logic is proposed. Based on this architecture, basic logic-gate architectures, ring oscillators, and edge-sensitive D-type flip-flops were fabricated using low-voltage p-channel organic thin-film transistors and integrated thin-film carbon resistors on flexible polymeric substrates. Mathematical analysis of this logic architecture indicates improved stability against charge-carrier-mobility degradation. A small-signal gain of 83 dB and a noise margin of 92 % of half the supply voltage have been measured. Owing to the intrinsic positive-feedback loop of the source-degenerated Schmitt-trigger logic, the design of the D-flip-flop enables a substantially smaller footprint and a considerably lower energy dissipation compared to previously reported unipolar organic-TFT-based D-flip-flop architectures. </p>

Organic field‐effect transistors (OFETs) have been extensively studied over the past decades because of their suitability for low‐cost, large‐area, and flexible electronics. However, improvements are needed to satisfy the demands of high‐speed applications. The switching speed of a logic device is affected by the charge‐carrier mobility (µ) and the square of the channel length (L) at a given gate–source bias. Therefore, increasing µ and/or reducing L are crucial for achieving high‐speed OFET‐based digital circuits. In this study, an n‐type OFET is fabricated with increased switching speed via a dual‐role approach involving solution‐grown, highly ordered single‐crystalline N,N'‐dioctyl‐3,4,9,10‐perylenetetracarboxylic diimide (PTCDI‐C8) wires, which serve as a mask for short‐channel formation up to the microscale and an active layer with enhanced charge mobility. Additionally, the performance of the n‐type short‐channel OFET and resistive‐load‐type inverters is evaluated. For comparative purposes, long‐channel (50 µm) devices with PTCDI‐C8 wires and short‐channel devices with a PTCDI‐C8 film are fabricated and the device performance is analyzed. The short‐channel device with the PTCDI‐C8 wires exhibits a significantly higher switching speed. Thus, the dual‐role approach is a simple and straightforward method for fabricating short‐channel devices, paving the way for further advancements in OFET technology requiring high switching speeds.
