The synthesis and properties of triazine-stilbene fluorescent brighteners containing a monophenolic antioxidant

Various triazine-stilbene fluorescent brighteners that were substituted with four different amine derivatives including a phenolic antioxidant on 4,4′-bistriazine moieties were synthesized. The obtained compounds (6a–m) were characterized by the analysis of proton NMR spectrum and confirmed by UV spectrum. The physical properties of the new compounds (6a–m) were determined by fastness test and whiteness measurement and compared with those of CI86.
