Abstract
Non-chlorinated solvents, especially for polar non-chlorinated solvents are highly desirable for the fabrication of organic field-effect transistors (OFETs) due to the environmental and healthy issues. In this paper, four polar non-chlorinated solvents, such as tetrahydrofuran (THF), ethyl acetate (EtAc), acetone (AT), and 2- methyltetrahydrofuran (2-MTHF), were used to fabricate the high-performance acceptor-donor-acceptor small molecule (IDTT-IDD-N) in OFETs. The effects of polar non-chlorinated solvents regarding optical properties, device performances, and microstructure 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 cm2V–1s –1 for THF, EtAc, AT, and 2-MTHF-processed devices, respectively. This work indicated that IDTT-IDD-N based OFETs fabricated from polar non-chlorinated solvents are really potential application in high-performance and environmental-friendly organic electronics.
