Abstract
본 발명은 현재 발광소자로 폭넓게 사용되고 있는 Alq3 [Tris(8-hydroxyquinone)aluminum complex]의 성질을 개선시켜 응용성을 높이기 위한 연구결과로서 보다 더 넓은 범위의 파장을 발광하는 물질로 사용하기 위하여 Alq3와 착물형성이 가능한 리간드(1)과 (2)를 용액상태에서 Alq3와 반응시켜 얻어진 새로운 모델의 발광소자의 합성법과 그 생성물에 속한다. Alq3와 반응한 리간드는 이 화합물이 가지는 색깔의 범위와는 다른 범위에서 발광하는 것으로 확인되었으며 반응생성물의 확인은 NMR과 UV/Vis 분광광도기로 측정하였다.The present invention is to improve the properties of Alq 3 [Tris (8-hydroxyquinone) aluminum complex] widely used as a light emitting device to improve the applicability of the present invention. It belongs to the synthesis method of the new model of light emitting element obtained by reacting ligand (1) and (2) which can form complex with 3 in the solution state with Alq 3 and its product. Ligands reacted with Alq 3 were found to emit light in a range different from the color range of the compound. The reaction product was determined by NMR and UV / Vis spectrophotometry.
