Industrial vat orange dyes for organic field effect transistors

Abstract

Organic field effect transistors (OFETs) have been an innovate field of research in many ways, starting from the synthesis of organic molecular and polymeric semiconductors, to exploring various device architectures for diverse fabrication methods and finally to establishing practical applications such as bio-electronic sensors, ion pumps, bio-integrated circuits, etc. These achievements have been possible because of the special properties of organic semiconductors, one of them being the easy, versatile, low energy device fabrication, due to inherently lower processing temperatures of organic materials compared to their inorganic counterparts. In this paper, we introduce a group of industrial vat orange dyes in OFETs, i.e. vat orange 1, vat orange 3 and vat orange 9, and investigate their processability and material properties via cyclic voltammetry, FTIR, UV-Vis spectroscopy, X-ray diffraction, photoluminescence, film forming characteristics by atomic force microscopy, and finally look into their charge transport in fabricated organic field effect transistors. These materials that have natural quinone moieties are highly appealing for future investigations in organic electronics applications including field effect transistors, solar cells and electrochemical energy storage.
