“…121,122 Hydrogen bonds can dominate crystalline small molecule organic semiconductors and direct packing patterns that offer efficient charge transport. [123][124][125][126][127] However, free hydrogen bond donors can decrease solubility and limit processability. Zhang et al reported an innovative solution to this problem by fabricating semiconductors with latent hydrogen bonding motifs.…”

Organic conjugated polymers and oligomers are key electronic materials for applications such as transistors, photovoltaics, and light emitting devices due to their potential for solution processability, mechanical flexibility, and precise structure-based tuning compared to inorganic materials. In dilute environments, the optoelectronic properties of conjugated polymers are largely governed by their constitutional structure and, to a lesser degree, their solution-state intramolecular configuration. In the solid state, intramolecular conformation and intermolecular electronic coupling impact these properties substantially, especially in relation to device performance. Therefore, an increasingly important area of research concerning conjugated materials is developing design strategies aimed at optimizing the solid-state packing for electronic applications. Programming solid-state packing arrangements through discrete non-covalent interactions is an emerging strategy within the context of conjugated polymers. This review focuses on the use of the two most prevalent discrete and directional interactions used to dictate the self-assembly of conjugated polymers and oligomers-hydrogen bonds and chalcogen bonds. We also discuss how these design motifs can imbue conjugated materials with appealing physical properties while simultaneously retaining or improving electronic capabilities.

“…Drop‐casting, in which the process solvent evaporation speed is usually slower than that of spin‐coating, is another simple laboratory‐scale solution‐processable fabrication technique for highly crystalline small‐area ultrathin films 56,102,103 . Because of the impinging drop momentum, the surface may be wet if it has high energy or the contact angle is low, as a result of which the film thickness is also dependent on the physical properties of the droplet, together with the substrate texture and wettability 66 .…”

In the past decades, a variety of organic field‐effect transistor (OFET) based sensors have been reported, holding great promise in physical sensing, chemical sensing, biosensing, medical sensing and functionalized integrated sensor arrays, thanks to the superiorities of OFETs, including fabrication versatility and high sensitivity to external stimulus. However, the sensing performance still needs to be enhanced to meet practical application requirements, especially high sensitivity and short response time. Among all the effective strategies, ultrathin organic semiconductor (OSC) film devices show significantly promoted sensing performance, and the fabrication methods to obtain these ultrathin OSC films are of importance and diversity. Here, a brief review focused on ultrathin (including molecular monolayer) OSC film fabrication methods is presented, including high‐vacuum thermal evaporation, solution‐processable methods, and the approach of combining ultrathin films with heterojunctions. Additionally, applications of ultrathin OFET‐based chemical and biological sensors are summarized. Finally, the outlook and challenges ahead are discussed. We hope this review can offer guidance for the fabrication methods and potential applications of ultrathin OFET‐based chemical and biological sensors in the future. © 2020 Society of Industrial Chemistry

“…solvatochromic behavior since they exhibit different colors in different solvents. Amino-substituted benzodifuranone (ABDF, Figure 1A) is a deep blue-colored dye that has attracted our attention due to its good photo-stability and interesting solvatochromic behavior Deng et al, 2018). The NH unit in the ABDF dye can undergo hydrogen bonding with the carbonyl group in the ABDF core .…”

High selectivity and sensitivity detection of fluoride anions (F − ) in an organic solution by the naked eye has always been a challenge. In this investigation, a simple compound based on aminobenzodifuranone (ABDF) was designed and synthesized. Deprotonation of the amino moiety caused by F − is responsible for a color change from dark blue to various colors (colorless, yellow, orange, and red) in different common organic solvents due to a blue shift over 200 nm in the UV/Vis spectrum. The color change is quite visible to the naked eye under ambient light. The detection limit for F − can reach a concentration of as low as 5.0 × 10 −7 M with high selectivity, even in a solution containing multiple anions.
