摘要：

We have prepared three pigments and six soluble dyes with thermal stability derived from diketo-pyrrolo-pyrrole (DPP) pigment by N-alkylation and dimerization. Synthesized dyes and pigments were measured by an absorption maximum (λmax) and thermal stability using a UV-VIS spectrophotometer and thermogravimetric analysis (TGA) respectively, comparing with C.I. Pigment Red 254. These dyes exhibited superior solubility to the organic solvents by introducing the linking group (n-octyl). DPP pigments have inferior thermal and solvent stability, which has so far inhibited their commercial adoption in color filter fabrication. The thermal stability of the N-alkylated dyes can be highly contributed by both the carbon number and their shapes of N-alkyl group in DPP ring. Copyright © Taylor & Francis Group, LLC.
