Vapor-deposited thin films of a newly developed sulfur-containing heteroarene, 2,7-diphenyl[1]benzothieno[3,2-b][1]benzothiophene (DPh-BTBT), were used as an active layer of OFETs, which showed excellent FET characteristics in ambient conditions with mobilities of approximately 2.0 cm2 V-1 s-1 and Ion/Ioff of 107.

Sublimed materials for organic electronic devices such of OFETs and OTFTs allow the achievement of better electronic properties, and may help increase a device’s lifetime.
Intrinsically stretchable active layers for organic field-effect transistors (OFET) are discussed. Polymer structural modification & post-polymerization modifications are 2 methods to achieve this.
Solution-processed organic photovoltaic devices (OPVs) have emerged as a promising clean energy generating technology due to their ease of fabrication, potential to enable low-cost manufacturing via printing or coating techniques, and ability to be incorporated onto light weight, flexible substrates.
