“…For this comparison, we used the small-molecule organic semiconductor 2,8-difluoro-5,11-bis(triethylgermyl-ethynyl) anthradithiophene (diF-TEG ADT), a material that exhibits charge carrier mobilities greater than 5 cm 2 ·V −1 ·s −1 and is compatible with large-area spray deposition (35). We first focused on crystals obtained by slow evaporation of the solvent using the solvent-assisted crystallization (SAC) technique (36). Typical transfer and transport characteristics are presented in Fig.…”

“…9 Dropcast film could also result in large crystalline domains thus give high charge mobility, e.g. in the case of derivatives pentacene, 10 but the average mobility is one order lower. This may hint the inhomogeneity of the film over large area.…”

New approach is presented for growth of pentacene crystalline thin film with large grain size. Modification of dielectric surfaces using a monolayer of small molecule results in the formation of pentacene thin films with well ordered large crystalline domain structures. This suggests that pentacene molecules may have significantly large diffusion constant on the modified surface. An average hole mobility about 1.52 cm2/Vs of pentacene based organic thin film transistors (OTFTs) is achieved with good reproducibility.

A selection of the latest developments in organic electronic materials and organic field-effect transistor (OFET) devices is reviewed here with an emphasis on the synthetic and manufacturing versatility, ease of processing, and low cost offered by solution processability. At the heart of these benefits is the nature of the weak van der Waals intermolecular interactions inherent to organic compounds. This allows processability with a relatively small amount of energy investment. Material solubility, in particular, creates unique pathways for film fabrication and the design of new device architectures, while presenting new manufacturing challenges to explore. In this review we provide a chronological presentation of the important developments in the solution-deposited organic small-molecule semiconductor, dielectric, and electrode materials used in OFETs, making specific note of current benchmarks. Organic device architectures and fabrication methods that are characterized by reduced complexity and ease of implementation are discussed.
