Abstract
An ethylene-sensitive sensor is described that includes a power source; an ethylene-sensitive semiconductor component electrically connected to the power source, the semiconducting component comprising a semiconducting organic compound; an input electrode electrically connected to the semiconductor component; and an output electrode electrically connected to the semiconductor component. The semiconductor material is at least partially exposed such that it can be contacted by a vapor. Methods of using the ethylene-sensitive sensor to detect ethylenic compounds are also described.
Claims16
An ethylene-sensitive sensor, comprising:
- a power source;
- an ethylene-sensitive semiconductor component electrically connected to the power source, the semiconducting component comprising a semiconducting organic compound combined with palladium particles and a porogen to introduce pores into the semiconducting organic compound, increasing surface area of the semiconducting organic compound;
- an input electrode electrically connected to the semiconductor component;
- and
- an output electrode electrically connected to the semiconductor component;
- wherein the semiconductor component is at least partially exposed such that it can be contacted by a vapor.
