Nanomaterials for detection of primary aromatic amine derivatives based on a fluorescent probe

Heterocyclic compounds bearing s-triazine and cyclotriphosphazene scaffolds: facile synthesis, hydrogen-bonded organic framework construction and fluorescent amine sensing

“…32 It is known that molecules with aldehyde units can react with amines through a Schiff base reaction, resulting in changes in their molecular structure and optical properties. 33 For example, Cheng et al synthesized an eight benzaldehyde-substituted fluorene dimer (8FP-2F), which could directly sense aniline vapor at room temperature as a multiple-anchored turn-off type fluorescent probe. 34 To date, many fluorescent heterocyclic compounds have been prepared and characterized for amine detection.…”
