Abstract

The invention relates to a perylene diimide derivative and application thereof, wherein the chemical structural general formula of the perylene diimide derivative is as follows:

Description

Perylene diimide derivative and application thereof
Technical Field
The invention belongs to the technical field of dye compounds, and relates to a perylene diimide derivative, a dye and application thereof.
Background
With the development of liquid crystal display technology, liquid Crystal Displays (LCDs) having low power consumption, no radiation, etc. have become the mainstream of the display market. Color filters are key devices for color display of LCDs, which must pass through Color Filters (CF) to produce color changes in the liquid crystal display. In the prior art, the manufacturing method of the color filter comprises the following steps: dyeing, pigment dispersion, printing, electrodeposition, inkjet, microcell electrolysis, electrophotography, thin film decomposition, multilayer interference film method, and the like. For example, color filters of medium and small size are generally manufactured by pigment dispersion, and specifically include: a black matrix is formed on a glass substrate, a layer of photoresist raw material is coated on the glass substrate with the black matrix, and a color photoresist pattern is formed after processes such as mask masking, exposure, development, etching, stripping and the like, for example, a red photoresist pattern can be formed first, the steps for forming the color photoresist pattern are repeatedly executed, and then a green photoresist pattern and a blue photoresist pattern can be formed, and then a color filter is formed through operations such as curing the color photoresist pattern, preparing a protective layer and the like.
Color Filters (CF) are an important component of liquid crystal displays and image sensors, and pigments or dyes as colorants have a critical effect on their optical properties and stability. Because of poor solubility of pigment, the pigment is easy to aggregate to cause large particles, increases light scattering and refraction, and causes low color purity and narrow color gamut. The dye in molecular state has good solubility in common organic solvents (such as Propylene Glycol Methyl Ether Acetate (PGMEA)) for preparing the color filter, avoids the defects of low transmittance and contrast caused by light scattering and refraction effects, and has the advantage of high color purity. Meanwhile, along with the requirements of the industry on high resolution, high light transmittance, high color purity, wide color gamut and high stability of the color filter. Therefore, dye-colorant-based color photoresists and color filters have been the focus of research in industry and academia in recent years.
Among the currently used main red colorants are azo (pigment red 242), pyrrolopyrrole dione (pigment red 242), anthraquinone (pigment red 177) and perylene diimide (pigment red 179), and these conventional red pigments or dyes have been difficult to meet the industrial requirements. Therefore, development of novel red dye with high color purity, wide color gamut and high stability is urgently needed.
Among them, perylene diimide structure is widely used and studied because of its advantages of high color strength, easy modification, excellent stability, and the like. Chinese patent application CN110003207a mentions that perylene diimide dyes with better solubility properties are prepared by introducing phenoxy into the bay site of perylene diimide, introducing trimethylphenyl or tri-hydrophilic chain phenyl into the imide site, and then polymerizing, the solubility is improved to some extent, but the existing perylene diimide dyes still have some defects as follows:
(1) The existing perylene diimide dye has poor absorption in the blue light wave band of 400-460nm, so that the color purity of red is insufficient, and the color gamut is narrower;
(2) The existing perylene diimide dye still has poor solubility in common organic solvents (such as Propylene Glycol Methyl Ether Acetate (PGMEA)) for preparing color filters, and undissolved particles can enhance light scattering and reduce brightness and contrast;
(3) The existing perylene diimide dye is still poor in heat resistance, so that the existing perylene diimide dye is difficult to maintain good light color when the color filter is post-baked at 230 ℃;
(4) The existing perylene diimide dyes are still poor in solvent resistance, resulting in difficulty in maintaining good light color when the color filter is developed.
Meanwhile, jeong Yun Kim et al (Jeong Yun Kim, synthesis and characterization of novel perylene dyes with new substituents at terminal-position as colorants for LCD color filter, J Incl Phenom Macrocycl Chem (2015) 82:203-212) synthesized six novel red perylene diimide dyes by changing the bay and imide functional groups of perylene diimide, which enhanced the solubility and at the same time improved the absorption of the prepared color filter at 650 nm. However, the synthesized dye still has the problems of poor absorption of 400-460nm, poor thermal stability and the like.
Martin Koenemann et al (Martin Koenemann, MULTIPLE CHROMOPHORES WITH A PERYLENEDIIMIDE SKELETON, EP3101087A 1) synthesized better optical performance perylene diimide dyes for use in color converters for Light Emitting Diodes (LEDs) or Organic Light Emitting Diodes (OLEDs) by introducing naphthalimide derivatives at the bay and imide positions of the perylene diimide. But only in the field of color converters, and does not improve the thermal stability and solvent resistance required in the field of color photoresists.
