The compound containing a bis(salicylaldehyde) end group has a structure as shown in formula (I), and a repeating structural unit in the polymer nanofiber has a structure as shown in formula (III), wherein R is selected from: C4-C10 alkylene. The compound containing a bis(salicylaldehyde) end group, used as a polymerization monomer, and hydrazine hydrate undergo dispersion polymerization in ethanol to prepare the polymer nanofiber. The polymer backbone contains a salicylaldehyde hydrazone group having aggregation-induced emission characteristics, and the obtained nanofiber has strong fluorescence in an aggregation state. The synthesis of the polymer nanofiber uses a step-by-step dispersion polymerization technology, the reaction concentration is high, the operation, separation and purification are simple, and the polymer nanofiber has potential application value in the field of fluorescence sensors.
