The electrical properties of organic semiconductors (OSCs), whether they are conjugated small molecules or polymers, can be tailored by incorporating electrically insulating units (EIUs), which are organic moieties consisting of nonconjugated units. EIUs can be introduced to a thin film by synthetically connecting them to the otherwise conjugated OSC molecules or by blending them in as separate EIU molecules with the OSCs during the thin‐film fabrication process. The engineered EIUs are capable of imparting various additional functions to the OSC thin film and improving their electrical properties. In this review article, a comprehensive overview of various effects of EIUs on OSC thin films and their consequent electrical performance when used as active layers in organic field‐effect transistors (OFETs) is provided. A broad range of studies of the synthetic approaches of incorporating EIUs, such as those using side chains, block copolymers, and conjugation‐break spacers, and of the blending approaches with organic insulators is discussed. Finally, a brief summary and perspectives for future research in this field are presented.

“…17 However, organic detection lms in these sensors are primarily fabricated utilizing expensive vacuum deposition processes and rigid Si/SiO 2 substrates. [20][21][22] In particular, spray-coating is a much cheaper and more practical technique to realize high performance low cost exible devices. Nevertheless, typical solution deposition methods such as spin-coating can easily damage most conventional polymer dielectric layers, e.g., inexpensive polymethylmethacrylate (PMMA) and polystyrene (PS) due to the solubility of these polymer lms in the processing solvents used for the active layers.…”

Flexible spray-coated TIPS-pentacene organic thin-film transistors as ammonia gas sensors

et al. 2013

Flexible ammonia (NH 3 ) gas sensors based on solution-processable organic thin-film transistors (OTFTs) are fabricated using a TIPSpentacene active layer/PMMA dielectric layer on glass and plastic substrates. These OTFT sensors exhibit outstanding NH 3 gas response and recovery characteristics under multiple exposure/evacuation cycles at controlled NH 3 concentrations.Organic thin-lm transistors (OTFTs) have attracted considerable attention due to low fabrication costs, lightweight, mechanical exibility, and compatibility with a wide range of applications such as backplanes for active matrix organic light-emitting diode (AMOLED) displays and radio frequency identication tags. [1][2][3][4] Recently, OTFTs were successfully incorporated into a variety of physical or chemical sensor devices. These OTFT-based sensors can efficiently detect multiple analytes, e.g., temperature, moisture, light intensity, pressure, and more importantly, various types of toxic gases. 5-10 Compared to widely used conventional semiconductor resistor sensors, OTFT-based sensors can efficiently translate the detected signals into changes in multiple electrical parameters, e.g., drain-source current (I DS ), eld-effect mobility (m), and threshold voltage (V T ). Moreover, the response signals of these sensors can be easily amplied by applying a higher gate voltage, V GS . † Electronic supplementary information (ESI) available: Detailed experimental section, AFM images of PMMA, trap density of OTFT sensors aer exposure to various NH 3 concentrations, lifetime of OTFT sensors, electrical characteristics of exible TIPS-pentacene OTFTs, and NH 3 response of OTFT sensors.

“…Molecular design and synthesis of organic semiconductors (OSCs) are indispensable to achieve high field-effect mobility, and numerous soluble OSCs such as side-chain-substituted acenes [1] and triethylsilylethynyl anthradithiophene [2] have been reported. The optimization of process conditions [3] or ink compositions [4] has been presented as an alternative approach toward high performance OTFTs. As the intrinsic field-effect mobility of conjugated molecules, especially that of small molecules, approaches 1 cm 2 V −1 s −1 and higher values, their performances are becoming comparable or even superior to those of hydrogenated amorphous silicon (a-Si:H).…”
