- Abstract
- Non-chlorinated solvents, especially polar non-chlorinated solvents, are highly desirable for the fabrication of organic field-effect transistors (OFETs) because they do not create environmental and health issues. In this paper, four polar non-chlorinated solvents, namely, tetrahydrofuran (THF), ethyl acetate (EtAc), acetone (AT), and 2-methyltetrahydrofuran (2-MTHF) were used to fabricate high-performance acceptor-donor-acceptor small molecules (IDTT-IDD-N) for OFETs. The effects of polar non-chlorinated solvents regarding optical properties, device performances, and microstructures were investigated in detail. High-performance OFETs were demonstrated with the hole mobilities of up to 1.01, 1.49, 2.40, and 0.81 cm(2) V-1 s(-1) for the THF, EtAc, AT, and 2-MTHF-processed devices, respectively. This work indicates that the IDTT-IDD-N-based OFETs fabricated from polar non-chlorinated solvents have potential applications in high-performance and environmentally friendly organic electronics.
