ORGANIC THIN FILM TRANSISTOR GAS SENSOR SYSTEM WITH MONOLAYER AS BLOCKING LAYER ON SOURCE/DRAIN ELECTRODES
A gas sensor system (100) for detecting conjugated hydrocarbons and/or esters in an environment. The gas sensor system includes two organic thin film transistor (OTFT) gas sensors (200, 300). The first OTFT gas sensor (200) allows for interaction of the conjugated hydrocarbon with the gas sensor's source and drain electrodes, and the second OTFT gas sensor (300) blocks the conjugated hydrocarbon from interacting with the gas sensor's source and drain electrodes. In the second gas sensor, a monolayer comprising 4-aminobenzenethiol and 4-fluorobenzenethiol may cover the source and drain electrodes preventing the conjugated hydrocarbon from interacting with the source and drain electrodes. The gas sensor system may be used to monitor a volatile conjugated hydrocarbon and/or an ester produced by fruit.
A method of using an organic thin film transistor (OTFT) gas sensor to measure an ester, e.g. butyl acetate, in a gas environment. The response of the OTFT gas sensor to the environment is used to determine the presence and/or the concentration of the ester in the environment. The OTFT gas sensor has source and drain electrodes (107, 109) in electrical contact with an organic semiconductor layer (111), a gate electrode (103), and a gate dielectric (105) between the organic semiconductor layer and the gate electrode. A monolayer (113) containing a protic group, e.g. an amino group, is bound to surfaces of the source and drain electrodes. The OTFT gas sensor allows for ester in the environment to interact with the protic group, which causes an output/change in output from the OTFT gas sensor. Measurement of the ester can be used to determine ripeness of fruit.

In addition, methods of producing such organic photodetectors and methods of tuning the resonance of a microcavity formed in an organic photodetector (OPD) to a predetermined wavelength are provided.
