“…Meanwhile, the complementary ring oscillator showed a higher voltage‐gain of ∼20 (enhanced detection of low analyte concentrations) and more adaptive feedback (improved background elimination) than the discrete transistor sensor. Fifthly, the employment of composite thin films as sensor active layers has been used to detect explosive vapors 156. In fact, composites are likely to exhibit enhanced sensitivity to other classes of chemical substances.…”

“…A special case of a “receptor” moiety is Cu tetraphenylporphyrin (TPP) acting as a complexing agent for nitro compounds through donor‐acceptor interactions. The addition of Cu TPP to a P3HT film in an OFET made the device sensitive to a wider range of nitrated explosives, including 1,3,5‐trinitro‐1,3,5‐triazacyclohexane (RDX), than was the original P3HT film alone 17. A combined coordination to the Cu and electron extraction by the RDX was believed responsible.…”

Organic semiconductor films are susceptible to noncovalent interactions, trapping and doping, photoexcitation, and dimensional deformation. While these effects can be detrimental to the performance of conventional circuits, they can be harnessed, especially in field-effect architectures, to detect chemical and physical stimuli. This Review summarizes recent advances in the use of organic electronic materials for the detection of environmental chemicals, pressure, and light. The material features that are responsible for the transduction of the input signals to electronic information are discussed in detail.

“…Many types of electrical transducer platforms utilizing organic semiconductors have been proposed and engineered to detect chemical compounds. The majority of chemical sensors are built on conventional platforms of resistors [1][2][3][4] and field-effect transistors [5][6][7][8][9]. The indication of chemical detection of these devices is mainly the change in resistance.…”
