“…It showed a hole mobility of 17.9 cm 2 V −1 s −1 with an on/off ratio of 10 7 . 97 As discussed above, the substituted units are normally symmetry units in BTBT-based molecules, which means the two substituted unit is the same. In some cases, the different substituted units will also result in surprising high mobility.…”

Organic semiconductors have been receiving intensive attention due to the specific advantages of low-temperature processing ability, low-fabrication cost, flexibility, and so forth. The charge carrier mobility of higher than 10 cm 2 V −1 s −1 for organic semiconductors is of great importance to be studied since it presents a future promising research direction toward commercial microelectronic applications. With the significant progress of the discovery of novel organic molecules and the further improvements of device fabrication technology, some organic molecules can break the limit of our knowledge and show very high mobilities. In this review, organic polymers and small molecules with mobilities above 10 cm 2 V −1 s −1 are first introduced to provide the readers with a general understanding of the features and characteristics of high-performance organic semiconductors. Then, some important parameters, including the molecular structures, the device configurations, and the performance, are discussed in detail. Finally, the clues to obtain high mobility are summarized, and the perspective toward the future possible research directions are also provided.

“…This molecule displayed a forty-fold improvement in charge mobility in OTFTs compared to the parent TTA due to its increased affinity for self-assembly into crystalline nanoribbons in solution. A cyclized thienothiophene core with benzothiophene arms has shown excellent hole mobility in the single-crystal state compared to its shorter thiophene analogue, owing to strong intermolecular contacts and increased effective π-conjugated surface [ 23 ]. Finally, a rigid dibenzosexithiophene unit has been copolymerized with bithiophene to afford a wide band-gap polymer for photovoltaic applications, albeit with modest performance due to the disordered polymer network [ 24 ].…”

Organic Thin Film Transistors Incorporating Solution Processable Thieno[3,2-b]thiophene Thienoacenes

Bottom-gate bottom-contact organic thin film transistors (OTFTs) were prepared with four novel star-shaped conjugated molecules containing a fused thieno[3,2-b]thiophene moiety incorporated either in the core and/or at the periphery of the molecular framework. The molecules were soluble in CS2, allowing for solution-processing techniques to be employed. OTFTs with different channel geometries were characterized in both air and vacuum in order to compare environmental effects on performance. Blending the small molecules with poly(styrene), an insulating polymer, facilitated the formation of an even semiconducting film, resulting in an order of magnitude increase in device mobility. The highest field-effect mobilities were in air and on the order of 10−3 cm2/Vs for three of the four molecules, with a maximum mobility of 9.2 × 10−3 cm2/Vs achieved for the most conjugated small molecule. This study explores the relationship between processing conditions and OTFT devices performance for four different molecules within this new family of materials, resulting in a deeper insight into their potential as solution-processable semiconductors.

“…In addition to organic small molecules, some crystalline polymer nanowires of poly( para ‐phenylene ethynylene) derivatives with thioacetate end groups (TA‐PPE), PDPP2TBDT and PDPP2TzBDT, and poly(10,12‐pentacosadiynoic acid) (poly‐PCDA) were also reported to have a high performance . It is noteworthy that the mobilities of many proposed molecules are more than 1 cm 2 V −1 s −1 , and some single crystals are even more than 10 cm 2 V −1 s −1 . The highest value, 42.7 cm 2 V −1 s −1 , is for single‐crystal nanowires of poly‐PCDA .…”

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.
