AB  - Five novel triarymethine derivatives containing a two chromophore moiety within the molecule have been designed, synthesized and investigated as potential color filter dyes. These new “dimer-type” triarylmethines showed increased photostability and thermal stability compared to the Victoria Blue BO unit and notably manipulation of the dye counter ion also led to increased thermal stability. To evaluate the dyes in color filters, filters were fabricated and the photo- and thermo-stability was determined after heat treatment (230 °C for 30 min). The fabricated color filters showed approximately 80% transmittance at 450 nm and the ΔEab values were in the range 3.03–9.26. These results indicate that the synthesized dimer-type triarylmethine derivatives have the potential for application as color filters for blue dyes.
