Easily solution-processed, high-performance microribbon transistors based on a 2D condensed benzothiophene derivative

Abstract

A 2D condensed benzothiophene derivative TBTDBT was synthesized. The thermal, optical and electrochemical properties were investigated. The single crystalline microribbons were grown by solution drop-casting and physical vapor transport methods respectively. The field effect transistors based on TBTDBT microribbons were fabricated and a mobility up to 2.62 cm(2) V(-1) s(-1) and an on-off ratio greater than 10(5) could be achieved.

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

“…There are a few examples in the literature of the synthesis and incorporation of 2D thienoacenes into organic electronic devices [ 21 ]; however, there are limited examples of fused thieno[3,2- b ]thiophene (TT) motifs, despite the fact that these few derivatives rank among the highest performing 2D thienoacenes. Zhang et al synthesized a small molecule comprised of a dithieno[3,2- b :2′,3′- d ]thiophene core with nine fused rings and seven sulphur atoms [ 22 ].…”

Quick Fabrication of Large-area Organic Semiconductor Single Crystal Arrays with a Rapid Annealing Self-Solution-Shearing Method

“…In addition, the quality of single crystals is largely dependent on the substrate because the slow crystallization process is very sensitive to the environment. For example, silicon dioxide (SiO 2 ) is the widely adopted rigid substrate for fabricating organic single crystals, which generally requires to be modified with a self-assembly monolayer such as octadecyltrichlorosilane (OTS) for optimizing the crystallization process 20 21 22 23 24 25 . Therefore, the practical application of organic single crystals in the microelectronic field is extremely restricted due to the above-mentioned disadvantages.…”

Asymmetric Cyclizative Dimerization of (ortho‐Alkynyl Phenyl) (Methoxymethyl) Sulfides with Palladium(II) Bisoxazoline Catalyst

“…[2] Benzothiophenes are presenti ns everald rug candidates, [3] and are widespread in materials chemistry. [4] Among them, bibenzothiophenes are also an importantc lass of compounds in functional materials [5a,b,g,j-n] andl igands.
