“…These values are still higher than other reported values with both unipolar and ambipolar OTFT devices. [16][17][18]32,33 To visualize the gate-tunable gas sensing behaviors of the A-OTFT effectively, we propose a color plot of the response to different concentrations of different gases as a function of V G , as shown in Fig. 4.…”

“…In addition, most previous studies reported their results measured in the controlled atmosphere only such as nitrogen box, far from practical sensor operating environment. [16][17][18] In this paper, we report an A-OTFT based gas sensor device operating in the ambient air to detect oxidizing NO 2 and reducing NH 3 , which are representative toxic gases and particularly relevant to health and safety. 19,20 NDTI-based materials, poly{[N,N 0 -bis(2-decylpentadecyl)naphtho[2,3-b:6,7-b 0 ]dithiophene-4,5,9,10-tetracarboxidiimide-2,7-diyl]-alt-5,5 0 -(2,2 0 -bithiophene)} (PNDTI-BT), having an excellent ambipolar property in ambient atmosphere [21][22][23] were used as the active sensing layer of the A-OTFT gas sensor.…”

“…Many new DPP derivatives are designed and demonstrate good performance as gas sensors combined with various morphology control. [81][82][83][84] Noh et al fabricated a precise control ultra-thin DPPT-TT film with only 2 nm in thickness through the bar-coating method, which exhibited obvious sensing to NH 3 , ethanol and even ethylene. [81] Its sensitivity ((I 0 -I gas )/I 0 ) is 82 % when exposure to 10 ppm ammonia.…”

Organic π‐conjugated materials, which have advantages of tailorable chemical structures, solution processability, and mechanical flexibility, are promising candidates for applications in low‐cost, portable gas sensors that operate at room temperature. Nevertheless, there are still challenging issues in the development of organic semiconductor gas sensors because of issues such as relatively poor sensitivity, slow response, and low recovery. Herein, we summarize the recent progress of gas sensors based on organic conjugated materials and discuss the critical factors related to the sensor performance and the operation mechanism. We highlight six types of typical materials from small molecule to polymer semiconductors with respect to their performance in detecting different gas species through morphology control and molecular engineering. Critical factors from gas kinetics to sensor‐analyte interaction are briefly discussed, together with an examination of sensing mechanisms.

Organic field-effect transistor (OFET)-based biosensors with antibody receptors are widely considered for protein antigen detection. To the authors' knowledge, there are no comparative evaluations to date of different choices for the matrix polymer to which the antibodies are attached. Herein, multiple acrylic copolymers are studied as receptor layers with myelin basic protein and its corresponding antibody as an archetypal antibodyantigen pair. Stability against multiple washing steps and the capacity for immobilizing antibodies on polymers on device surfaces with the help of fluorescein isothiocyanate-labeled antibodies are compared. Electronic detection and selectivity are also observed. The conclusions provide guidance on the selection of bioreceptor material for increasing sensitivity and process stability of OFET biosensors.
