A method of detecting an analyte in a sample including a carbon-carbon multiple bond moiety comprising:
- exposing a detection region of a detector including a compound having an extrudable group and capable of undergoing Diels-Alder reaction with the analyte including a carbon-carbon multiple bond moiety to the sample, and
- detecting a property change of a reaction mixture comprising the heteroaromatic compound based on the presence of the analyte in the sample.
A detector for detecting an analyte comprising:
- a housing including a detection region comprising
- a compound having electron donating or withdrawing character and capable of undergoing Diels-Alder reaction with the analyte including a carbon-carbon multiple bond moiety, and
- a conducting material that changes conductivity after the Diels-Alder reaction.
