제목 Relationship Between Luminescent Property and Connecting Position of SideGroup in Bis(dipyrrinato)zinc Complex Derivatives
초록 New yellow green emitting materials were synthesized using bis(dipyrrinato)zinc complex moiety and phenyl or naphthalene group. Position 5 of dipyrrinato group was linked with position 1 or 2 of naphthalene group and phenyl group. Bis[5-(1-naphthalenyl)-dipyrrinato]zinc complex (Zn(1-NaPN)2) using position 1 of naphthalene side group showed about 10 times stronger photoluminescent property and sharper PL spectrum compared to bis[5-(phenyl)-dipyrrinato]zinc complex (Zn(PPN)2) and bis[5-(2-naphthalenyl)-dipyrrinato]zinc complex (Zn(2-NaPN)2). EL performance of non-doped organic light emitting diodes (OLEDs) device was shown identically in the result of optical properties in film state. Luminance efficiency (cd/A) of Zn(1-NaPN)2 was 0.33 cd/A, which was about 4 ~ 8 times higher than Zn(PPN)2 and Zn(2-NaPN)2 at 0.04 and 0.08 cd/A, respectively. Quantum efficiency of Zn(1-NaPN)2 in EL was also about 2 ~ 3 times higher than Zn(PPN)2 and Zn(2-NaPN)2.
