Synthesis and Application of Oil-Soluble Red Dyes Derived from p-n-Alkyl Aniline

摘要

In this study, the azo red dyes derived from p-n-alkyl aniline by the introduction of different alkyl groups having high solubility in dodecane were synthesized. Results indicated that the elementary properties of red oil inks were 1) non-polarity;2) low viscosity (<3.0 cps);3) specified surface tension (<30 mN/m);4) intensity of visible absorption covering 480 - 540 nm;5) hue close to standard red (CIE(x, y) = 0.67, 0.33). We can conclude that these azo red dyes are applicable for electrowetting displays.
