A study on the fluorescence property of the perylene derivatives with methoxy groups

Perylene-based dyes with methoxy groups at various positions were synthesized to understand the effect of the methoxy groups on the fluorescence quenching. Additionally, perylene-based dyes with ethyl groups in place of the methoxy groups were also synthesized to serve as control. Absorption and fluorescence properties of the dyes were measured, and then, density functional theory (DFT) and time-dependent density functional theory (TD-DFT) simulations were conducted. The methoxy groups of terminal-substituents had a lesser effect on fluorescence quenching than the methoxy groups of bay-substituents. Moreover, only the methoxy groups at the para-position of the bay-substituents strongly affected on fluorescence quenching. These results showed that the fluorescence of the dyes are influenced by the electron donating effect of the methoxy groups when the methoxy groups are involved in the main conjugation systems of the dyes.

The effect of fluorescence of perylene red dyes on the contrast ratio of LCD color filters

Dye-based and pigment-dye hybrid color filters are recommended to overcome the drawbacks such as light scattering of traditional pigment-based color filters. However, dyes used as colorants for LCD color filters may exhibit strong fluorescence. Fluorescence lowers the contrast ratio of color filters by increasing brightness in the full-black state and affects optical performance of displays. In this study, the correlation between dye fluorescence and the optical properties of color filters was investigated. Six perylene-based dyes were synthesized, and dye-based and pigment-dye hybrid color filters were prepared with each dye. The fluorescence properties of the synthesized dyes in solution and the prepared color filters were evaluated. The maximum brightness and the contrast ratio of the color filters were measured, from which the minimum brightness of the color filters was calculated. All dye-based and pigment-dye hybrid color filters showed greater minimum brightness than pigment-based one due to emission in the visible region.

Synthesis and characterization of novel perylene dyes with new substituents at terminal-position as colorants for LCD color filter

Six novel red perylene dyes were synthesized by modifying the bay- and terminal-positions of perylene main body to improve the optical performances of liquid crystal display (LCD) color filters. The absorption properties, solubility in industrial solvents and thermal stabilities of the dyes were examined to evaluate the dyes for dye-based LCD color filter. Mill bases and spin-coated color filters were formulated and fabricated using the synthesized dyes. Transmittance, dye aggregation and thermal stabilities of the prepared color filters were investigated using a color spectrophotometer. Geometric structures of the synthesized dyes were optimized by using Gaussian program. Five of the synthesized dyes showed acceptable optical properties as colorants for LCD color filters. Also, the synthesized dyes and prepared color filters exhibited suitable thermal stability for the application. Furthermore, the prepared color filters exhibited superior transmittances than pigment-based color filters at 650 nm. Their physical properties were closely related with chemical structures investigated by geometry optimization.

Facile synthesis and characterization of novel coronene chromophores and their application to LCD color filters

New coronene derivatives, diphenylcoronene tetracarboxdiimide and monophenylbenzoperylene tetracarboxdiimide, were synthesized from N,N'-bis(2,6-diisopropylphenyl)-1,7-dibromoperylene-3,4,9,10-tetracarboxdiimide via a one-step reaction. The suggested synthetic route is the simplest and most economical among the methods to extend the aromatic systems along the short molecular axis of perylene. The synthesized molecules exhibited superior stability and color strength as yellow chromophores. They were characterized by significant hypsochromic shifts of the absorption compared to perylene tetracarboxdiimide and high fluorescence quantum yields.

Synthesis and characterization of some perylene dyes for dye-based LCD color filters

Eight red perylene dyes were synthesized to improve the optical performance of LCD color filters. Among them, dyes with bulky functional substituents at the bay and terminal positions were highly soluble in cyclohexanone, the industrial solvent currently used in the pigment dispersion method. The spectral properties and thermal stability of the dye-based color filters with these dyes were examined by comparing them with pigment-based ones. The prepared color filters exhibited superior spectral properties due to the smaller particle size of the dyes, which led to less light scattering. However, their thermal stability varied with the dye structures, and only the dyes mono-substituted at the bay position had sufficient thermal stability.
