Abstract

In order to discover materials that can be used for OLED, extractions of marine microalgae was screened for photoluminescence(PL) properties and analyzed using gas chromatography-mass spectrometry(GC-MS). The extractions of Nitzschia denticula, Navicula cancellata and Nannochloropsis salina showed PL spectroscopy among fourteen marine microalgae species. The selected three fractions from three microalgae were analyzed by GC-MS. According to the results, it was found that the identified organic light-emitting materials can be subdivided into three functional groups based on imidazole, purine and quinoline. These chemicals are considered to have a strong relationship with PL spectroscopy for OLED materials.

본 연구는 해양 미세조류에서 추출한 물질에 대한 광 발광(Photoluminescence) 측정 및 GC-MS 분석을 통해 유기발광다이오드 소자로 이용 가능한 물질을 탐색하고자 하였다. 국내에서 주로 서식하는 해양 미세조류 14종의 추출물을 분획으로 얻었으며 광 발광 측정 결과, Nitzschia denticula, Navicula cacellata, Nannochloropsis salina 총 3종의 추출물에서 광 발광 반응이 나타났다. 광 발광 반응을 보인 물질의 특성을 알아내기 위해 GC-MS로 분석하였으며, 그 결과 3종의 추출물이 imidazole, purine 및 quinoline기를 가진다는 것을 확인하였고, 이 계열의 물질들이 광 발광에 영향을 주는 것으로 판단된다.
