“…The edge casting method developed by Takeya et al resulted in SC‐OTFTs showing high mobilities of up to 11 cm 2 V −1 s −1 . On the other hand, 5,14‐ N ‐phenylmaleimidedinaphtho[2,3‐b:2′,3′‐f]thieno[3,2‐b]thiophene is another soluble DNTT derivative, a precursor of the parent DNTT, which can be used for fabricating OTFTs by conventional solution processing followed by thermal annealing . Our recent work suggests that the DNTT precursor/PS blend after thermal annealing can be used to obtain crystalline DNTT thin films segregated under the PS layer and the OTFTs fabricated with these thin films showed mobilities of 1.1 cm 2 V −1 s −1 …”

High-mobility short-channel organic thin-film transistors fabricated using a dinaphtho[2,3-b:2',3'-f]thieno[3,2-b]-thio--phene (DNTT) precursor (5,14-N--phenylmaleimide DNTT, endo-isomer-rich fraction) and polystyrene (PS) blends are reported. The DNTT grains are "single-crystal"-like and the field-effect mobility of the devices ranges up to 4.7 cm(2) V(-1) s(-1). The PS layer functions as a hydrophobic passivation layer on the Si/SiO2 substrate.

“…The subsequent crystallization and transfer of single crystals to asubstrate led to semiconductors with 2D morphologies.The results indicate that the 2D single crystals of DNTT obtained by this method can achieve ah ole mobility of 2.4 cm 2 V À1 s À1 . [82] Recently,2Dfabrication technology has been improved to make the solution self-assembly method suitable for many organic small molecules.T he principle behind this method is similar to the crystal growth method of liquid-liquid diffusion. As shown in Figure 6, adrop of asolution saturated with the object molecule,s uch as perylene,i sf irst drop-cast onto aw ater surface (Figure 6a); here,t he water surface can be regarded as an ideal substrate to grow 2D single crystals epitaxially.…”

Organic semiconducting single crystals are perfect for both fundamental and application‐oriented research due to the advantages of free grain boundaries, few defects, and minimal traps and impurities, as well as their low‐temperature processability, high flexibility, and low cost. Carrier mobilities of greater than 10 cm2 V−1 s−1 in some organic single crystals indicate a promising application in electronic devices. The progress made, including the molecular structures and fabrication technologies of organic single crystals, is introduced and organic single‐crystal electronic devices, including field‐effect transistors, phototransistors, p‐n heterojunctions, and circuits, are summarized. Organic two‐dimensional single crystals, cocrystals, and large single crystals, together with some potential applications, are introduced. A state‐of‐the‐art overview of organic single‐crystal electronics, with their challenges and prospects, is also provided.
