A Solution-Processed Air-Stable Perylene Diimide Derivative for N-type Organic Thin Film Transistors

Abstract

For future all-soluble organic thin film transistor (OTFT) applications, a new soluble n-type air-stable perylene diimide derivative semiconductor material with (trifluoromethyl)benzyl groups (TC-PDI-F) is synthesized. The film is formed by spin-coating in air and optimized for OTFT fabrications. The transistor characteristics and air-stability of the TC-PDI-F OTFTs is measured to investigate the feasibility of using solution-processed TC-PDI-F for future OTFT applications. For all-solution OTFT process applications, the transistor characteristics are demonstrated by using TC-PDI-F as an n-type semiconductor material and liquid-phase-deposited SiO(2) (LPD-SiO(2) ) as a gate dielectric material. All processes (except material synthesis and electrode deposition) and electrical measurements are conducted in air.

Comparative study of soluble naphthalene diimide derivatives bearing long alkyl chains as n-type organic thin-film transistor materials

“…[6,7] One particular target is the development of soluble n-type materials with high device performance. [8][9][10] This is highly desirable for the formation of high-performance complementary circuits composed of p-and n-channel TFTs having similar performance [11] and for the realization of low manufacturing costs in real terms using solution processes, which is one of the greatest potential benefits of organic semiconductors. [12] Perylene tetracarboxylic acid diimides (PTCDIs) are among the most promising n-channel candidates for organic TFTs because of their high electron affinity and large π-orbital overlap in the solid state.…”

[9,10,[13][14][15][16][17][18][19] Many substituents have been introduced in PTCDIs to, for example, improve electron mobility, enlarge electron affinity for operation stability in air, and improve solubility in common solvents.…”

New air-stable solution-processed organic n-type semiconductors based on sulfur-rich core-expanded naphthalene diimides

“…Indeed, organic n-type air-stable semiconductors have been intensively explored recently. [23][24][25][26][27][28][29] However, organic n-type air-stable semiconductors with high electron mobilities are still limited.…”
