Tetrabenzocorrolazine dyes with high color strength and broad absorbance derived from a phthalocyanine moiety were designed and synthesized for a color filter on an array-mode black matrix of low dielectric constant. The prepared tetrabenzocorrolazine dyes focused the absorbance of phthalocyanine further into the visible light range so that the color was considerably closer to black, while making it easier to introduce an axial substituent in the vertical direction to the dye main body, thereby markedly improving its solubility in industrial solvents. Upon mixing with a perylene dye of 450-550 nm absorbance and a thermosetting resin composition, dye-based black matrix films with high optical density values, associated with superior light shielding capability, were fabricated. The prepared black matrix films not only ensured thermal resistance by allowing easy intermolecular cohesion but also served as an insulating membrane that did not interfere with the thin film transistor electric signals, exhibiting a value of 3-5 when dielectricity was measured as the most critical factor for the color filter on array mode display panels.

低介电常数的宽吸收四苯并咔咯嗪染料黑矩阵的研究

设计并合成了具有高颜色强度和广泛吸收的酞菁部分的四苯并科咯嗪染料，用于低介电常数的阵列模式黑色矩阵上的彩色滤光片。所制备的四苯并可咯嗪染料将酞菁的吸光度进一步集中在可见光范围内，使颜色更接近黑色，同时更容易在染料主体的垂直方向上引入轴向取代基，从而显着提高其在染料中的溶解度。工业溶剂。在与吸光度为 450-550 nm 的苝染料和热固性树脂组合物混合后，可以制造出具有高光密度值和优异遮光能力的基于染料的黑色矩阵薄膜。
