Pigment yellow 180 (P.Y.180), a kind of benzimidazolone, has been widely used in various industrial fields of ink, paint, plastics, toner, and color filter, etc. This is a high performing pigment that is a greenish yellow shade with excellent properties such as heat resistance, solvent resistance, acid resistance and alkali resistance. In this study, pigment compounds were synthesized using various coupling reaction temperature condition. The properties of samples crystallized under various solvents and temperature conditions using autoclave pressurizer were also investigated. The pigment crystallized using DMSO solvent treatment showed the improvements such as the increase of X-ray intensity ratios and particle size, high color strength, and enhanced dispersibility.

In this study, the diarylide compound pigment of high hiding power and vivid color was synthesized successfully by controlling several factors such as pH, coupler solution temperature, kind and addition amount of dispersion precursor, and crystallization temperature in the process of coupling synthesis. The properties of samples were measured by the means of FT-IR, UV-Vis spectroscopy, PSA, zeta potential, and turbiscan. It was found that the highly dispersive sample could be prepared by introducing the dispersive precursor.

In this study, to obtain isoindoline compounds with the high thermal resistance and reddish yellow color using an environmental friendly method without the use of any surfactants, isoindoline derivatives with different structures were added at various reaction temperatures for the synthesis and the product was then crystallized by controlling temperatures and times in autoclave. Chemical structures, particle sizes, color differences, and optical properties were evaluated by the means of FT-IR, FE-SEM, UV-Vis spectroscopy, PSA (particle size analyzer) and Zeta potential analyzer. The samples with an enhanced dispersibility, highly thermal resistance, uniform particle sizes were achieved possibly due to the addition of isoindoline derivatives into the crystallization processing mixtures. The color change trend was also observed depending upon synthesis conditions.

블루 안료 15 : 6이라 불리는 ε결정상의 동프탈로시아닌(ε-CuPc)는 LCD 패널에서 청색화소를 제공하는 중요한 소재로써, 본 연구에서는 ε-CuPc 시료를 ε-CuPc 나노 입자를 seed로 이용하는 방법으로 여러 조건에서 합성하여 적합한 용매 및 온도조건 등을 규명하였고, 이를 미리 합성한 α 및 β 결정상의 CuPc 시료들과 비교함으로써 ε-CuPc 시료의 결정상, 결정 순도, 합성 수율 및 미세구조를 상호 비교·분석하였다. 시료들의 화학 구조 및 결정 구조는 푸레어 변환적외선(FT-IR) 분광기 및 X선 회절 분석기(XRD)를 이용하여 각각 비교 분석하였다. 또한, 입자의 형상 및 크기는 주사 전자현미경(FE-SEM)으로 비교 분석하였고, 열적 특성은 열중량분석기(TGA)를 이용하여 비교 분석하였다. The ε type copper phthalocyanine (ε-CuPc), called as a pigment blue 15 : 6, is a significant material to produce a blue pixel in LCD (Liquid Crystal Display) panel. In this study, ε-CuPc sample was synthesized at various reaction conditions by applying the seed method using ε-CuPc nanoparticles as a seed. Adequate synthetic conditions of the samples were selected by analyzing and comparing crystalline structure, crystalline purity, microstructure, and synthetic yield of the samples with α and β crystalline CuPc samples. The chemical and crystalline structure of the samples were tested using FT-IR spectrometer and X-ray diffractometry, respectively. The shape of the particle was examined using field emission scanning electiron microscope while the thermal property was tested utilizing thermogravimetric analysis.

본 연구에서는 벤젠고리의 a와 β·위치에 phenoxy, 2-naphthoxy 또는 4-trityl phenoxy 치환기가 도입된 프탈로니트릴 유도체들을 합성하였고, 이들 중간체들을 이용하여 전자 주게 특성을 가지는 치환기가 도입된 oxovanadium phthaloeyanine (YOPc) 유도체들을 성공적으로 합성하였다. 시료들의 구조 특성 및 분자량은 (1)H-NMR, FT-IR 및 MALDI-TOF형 질량분석기률 이용하여 측정·분석하였고, 광학적 및 화학적 특성은 UV-Vis 분광기, X-ray 회절기 및 열분석기를 이용하여 측정·분석하였다. 합성된 VOPc 유도체들의 최대흡수파장 값은 약 684~726 nm이었으며, 치환기의 도입으로 말미암아 용해도가 향상되거나 Q 밴드가 이동하였다. After phthalonitrile derivatives were synthesized by the introduction of phenoxy, 2-naphthoxy or 4-trityl phenoxy group on α-and β-position, oxovanadyl phthalocyanine (VOPc) derivatives containing electron-rich substituent group at different position were synthesized successfully in this investigation. The chemical structure of samples was determined by the means of (1)H-NMR, MALDI-TOF mass spectroscopy, and FT-IR spectrometer. Also, optical and chemical properties were determined by the means of UV-Vis spectrometer, X-ray diffractometry, and thermo gravimetry. It was found that the maximum absorbing wavelength of VOPc derivatives ranged from 684 to 726 nm. Also, their solubility and Q-band were enhanced and shifted by the introduction of substitute group, respectively.
