  Abstract

A series of novel bi-heterocyclic disperse dyes containing N-ethyl-3-cyano-4-methyl-6-hydroxy-2-pyridine group were synthesized. The structures of the bi-heterocyclic dyes were characterized by Fourier transform infrared spectroscopy (FT-IR), nuclear magnetic resonance spectroscopy (1H-NMR), UV-vis spectrophotometry, and elemental analysis. The distinct spectral behavior and solvatochromic effect of the dyes were discussed. The dyeing properties of the dyes for polyethylene terephthalate (PET) fabric were investigated. Novel bi-heterocyclic disperse dyes had higher molar absorption coefficient, good color strength, and excellent fastness properties, especially light fastness. The bi-heterocyclic disperse dyes have potential research value in the development of high light resistant dyes and functional dyes.
