A novel method for soluble hydrophilic anthracene derivative self-assembled on APTES in air

A hydrophilic organic semiconductor, anthracene derivative (ATC) was self-assembled on hydrophilic SAM 3-aminopropyltriethoxysilane (APTES) by solution process in air. The APTES self-assembled on the insulator surface was found to help to align the packing of ATC thus improve the crystallinity of ATC thin film. The first attempt to fabricate organic thin film transistors (OTFTs) using self-assembled ATC via this approach was made with and the performance of OTFTs was also measured in ambient condition.

► A hydrophilic organic semiconductor, ATC was self-assembled on hydrophilic SAM APTES for OTFTs fabrication by solution process in air.
► The APTES self-assembled on the insulator surface was found to enhance the crystallinity of ATC thin film.
► This result implied this approach can be applied to the OTFT fabrications which needs purely hydrophilic system for selective formation in the future.
