The invention relates to a compound for rapid detection of triethylene diamine. With Anthracene selected as a reaction substrate, multi-step reaction is made under certain organic reaction conditionsby using an organic synthetic chemical method to synthesize a molecular-tweezer-structure compound containing a biurea functional group; and a the synthesized compound (molecular tweezers) for rapid detection of triethylene diamine is used as a main body by using the basic principle and method of molecular recognition in supramolecular chemistry and triethylene diamine is well detected in an organic solvent by using a molecular fluorescence technology. Therefore, trace triethylene diamine molecules in an organic phase can be recognized in a high-sensitivity and high-selectivity mode. The method is simple and the pretreatment operation is not needed in the recognition process.
