Recent Structural Engineering of Polymer Semiconductors Incorporating Hydrogen Bonds

Abstract

Highly planar, extended π‐electron organic conjugated polymers have been increasingly attractive for achieving high‐mobility organic semiconductors. In addition to the conventional strategy to construct rigid backbone by covalent bonds, hydrogen bond has been employed extensively to increase the planarity and rigidity of polymer via intramolecular noncovalent interactions. This review provides a general summary of high‐mobility semiconducting polymers incorporating hydrogen bonds in field‐effect transistors over recent years. The structural engineering of the hydrogen bond‐containing building blocks and the discussion of theoretical simulation, microstructural characterization, and device performance are covered. Additionally, the effects of the introduction of hydrogen bond on self‐healing, stretchability, chemical sensitivity, and mechanical properties are also discussed. The review aims to help and inspire design of new high‐mobility conjugated polymers with superiority of mechanical flexibility by incorporation of hydrogen bond for the application in flexible electronics.

Water-soluble conjugated polymers for bioelectronic systems

“…153 WSCPs offer many functionalities, such as electron and ion transport properties, and soft mechanical properties, and are easily adjusted by chemical design, making them a promising bridge between biological systems (usually hydrated ions) and electronic devices (electrons). [154][155][156] Brain-inspired artificial neural networks have been implemented in prosthetics and brain-computer interfaces. [157][158][159] While promising, these applications are highly dependent on artificial neural network algorithms.…”

Self-assembled discotics as molecular semiconductors

“…Organic semiconductors and their applications in optoelectronic devices have been extensively reviewed till date, and the readers can form a fair idea regarding the polymeric and single crystalline materials employed in this field. 152–159 Liquid crystalline molecules, however, are comparatively much less explored from such a perspective. 160…”

Polymer-Unit Fingerprint (PUFp): An Accessible Expression of Polymer Organic Semiconductors for Machine Learning

“…As shown in Figure 10c, the coplanarity of the polymers is enhanced by the van der Waals force between nitrogen atoms in the pyridine and fluorine atoms in thiophene. 67,68 In addition, the nitrogen atoms in the double ring and the fused ring can improve the electrophilicity of the ring. Moreover, the introduction of fluorine atoms also promotes the closer π−π stacking between conjugated polymers.…”
