Research Papers : The Study for Synthesis and Characteristic of α,β-tetra(phenoxy, 2-naphthoxy, 4-tritylphenoxy) Oxovanadium Phthalocyanine Derivatives
Abstract
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.
연구논문 : α, β-tetra(phenoxy, 2-naphthoxy, 4-tritylphenoxy) Oxovanadium 프탈로시아닌 유도체의 합성 및 특성에 관한 연구
초록
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.
