[0002] Naphthyridine is a type of heterocyclic compound with the chemical formula C8H6N2. Its structure can be seen as two CH atoms of naphthalene replaced by two nitrogen atoms. Naphthyridine has 10 isomers. Because naphthyridine has two benzene rings, it has a strong π-π conjugation and has relatively good luminescence properties.

[0003] Most of the existing naphthyridine compounds are produced in a reaction tank. The naphthyridine compounds react in the reaction tank for a certain period of time and then are discharged. However, some of the naphthyridine compounds will adhere to the side wall of the reaction tank. Therefore, the naphthyridine compounds remaining on the side wall of the reaction tank are mixed with the naphthyridine compounds added subsequently, which will lead to the purity of some naphthyridine compounds. In addition, the naphthyridine compounds that adhere to the side wall of the reaction tank for a long time will undergo qualitative changes, thereby affecting the subsequent processing of the naphthyridine compounds.
