제목 Synthesis and Optical Properties of Pentacene Derivatives Using Fluorene and Carbazole Moieties
초록 We substituted fluorene and carbazole moieties into pentacene compound for comparing optical and EL properties together. The molecular structure was confirmed by NMR, IR, UV–Visible spectroscopies and FAB-Mass analysis. Flu-PTC-Flu and Cz-PTC-Cz exhibited similar red PL spectrum pattern and their maximum wavelengths appeared at 627 nm and 633 nm. ITO/m-MTDATA/NPB/Alq3:Flu-PTC-Flu (5%)/LiF/Al device showed red EL spectrum at 636 nm with 0.03 cd/A efficiency. ITO/m-MTDATA/NPB/Alq3:Cz-PTC-Cz (5%)/LiF/Al device also exhibited similar red EL spectrum at same range and higher efficiency (>0.21 cd/A) than Flu-PTC-Flu. We propose the dopant EL property of pentacene derivatives can be changed as the electronic property and steric effect of 6,13-substituted moiety in 6- and 13-positions.
