“…[60][61][62] The critical effect of regioregular structures on the charge transport properties closely correlates with their distinct molecular packing patterns and lm morphology. [63][64][65][66] Here, the outward imide units in F3 are more favorable for intermolecular packing than the inward ones in F1, thereby enabling a much higher m h value.…”

“…In 1994, Garnier et al fabricated the first all‐polymer FET (including the electrodes) realized by printing techniques, where polyester was chosen as the dielectric layer and an adhesive tape worked as the substrate . Tremendous exploration in flexible OFETs has been conducted ever since then, including modification of the molecular structure and design of new molecules, devising of new device geometry like the hybrid system, and development of new fabrication processes exemplified by ultrathin film fabrication . Here, in terms of flexibility, we mainly focus on polymer molecules which are naturally flexible property and we also explore some typical organic small molecules.…”

The emergence of flexible organic electronics that span the fields of physics and biomimetics creates the possibility for increasingly simple and intelligent products for use in everyday life. Organic field‐effect transistors (OFETs), with their inherent flexibility, light weight, and biocompatibility, have shown great promise in the field of biomimicry. By applying such biomimetic OFETs for the internet of things (IoT) makes it possible to imagine novel products and use cases for the future. Recent advances in flexible OFETs and their applications in biomimetic systems are reviewed. Strategies to achieve flexible OFETs are individually discussed and recent progress in biomimetic sensory systems and nervous systems is reviewed in detail. OFETs are revealed to be one of the best systems for mimicking sensory and nervous systems. Additionally, a brief discussion of information storage based on OFETs is presented. Finally, a personal view of the utilization of biomimetic OFETs in the IoT and future challenges in this research area are provided.

“…During an international forum in 2018, the future technology of the third generation of organic light-emitting diodes (OLEDs) for display purposes was eco-friendly defined in terms of low power consumption and long lifetime [ 12 ]. However, after carrying out a search, zero results were returned for green technologies for n-type organic transistors, except one regarding green solvents [ 13 ].…”

Sulpho-Salicylic Acid Grafted to Ferrite Nanoparticles for n-Type Organic Semiconductors

et al. 2020

A disadvantage of the use of pentacene and typical organic materials in electronics is that their precursors are toxic for manufacturers and the environment. To the best of our knowledge, this is the first report of an n-type non-toxic semiconductor for organic transistors that uses sulpho-salicylic acid—a stable, electron-donating compound with reduced toxicity—grafted on a ferrite core–shell and a green synthesis method. The micro-physical characterization indicated a good dispersion stability and homogeneity of the obtained nanofilms using the dip-coating technique. The in-situ electrical characterization was based on a point-contact transistor configuration, and the increase in the drain current as the positive gate voltage increased proved the functionality of the n-type semiconductor.

Highly-stable, green-solvent-processable organic thin-film transistors: angular- vs. linear-shaped carbazoledioxazine derivatives

Abstract: Linear-shaped carbazoledioxazines can be processed from green solvents and exhibit a two orders of magnitude higher mobility than their angular-counterpart.
