디스플레이용 광기능성소재의 마이크로파 합성 및 특성에 관한 연구

Abstract

Phthalocyanines are one of the most famous pigments because of their thermal and chemical stability. They have been used for dyes, ink and other colorants since 1930s. After it has been discovered nonlinear optical character of phthalocyanine, many researchers have investigated and synthesized to apply many fields such as chemical sensor, photovoltaic cells, xerography, optical disk, non-linear optics and display materials, etc. The microwave processing has been applied in pulp drying, food cooking, organic synthesis, ceramic sintering, composite joining and chemical analyses because of the inherent advantage of microwave heating, which is selective, direct, rapid, internal and controllable. Microwave processing in organic synthesis leads some advantages such as high yield and reducing reaction time, clean product comparing with conventional method. In this study, ε-type copper phthlaocyanine used as LCD color filter and subphthalocyanine derivatives applied as PDP neon cutting material were synthesized at various conditions by microwave synthetic process and conventional synthetic process. The polymer film containing subphthalocyanine derivatives were made as neon cutting film of PDP and its optical property was investigated. Successful synthesis of sample was confirmed by H-NMR and FT-IR. UV-Vis property was measured by UV-VIS spectroscopy. Also, crystal structure was determined by XRD.
