The Synthesis and Characterizations of Thermally-Stable Yellow Metal Complex Dyes for LCD Color Filters
Eight kinds of yellow metal (III) complex azo dyes were synthesized using different diazo component, coupling component and metal ion. The effect on the thermal stability of the synthesized dyes by azo ligand with two different functional groups, alcohol and carboxylic acid, was studied. The characteristics of the synthesized dyes were examined by their absorption maxima, thermal stability by a thermogravimetric analysis (TGA), and the chromatic characteristics of the fabricated films were measured. It was also explained that the effect of functional groups on the thermal stability of the dyes as well as their chromaticity values.
