Abstract

New blue fluorescent compounds containing tetra-substituted ethylene moieties have been designed and synthesized. By fabricating multilayered non-doped OLED devices using these new blue materials, we achieved luminance efficiencies of 4.00 lm/W (10.33 cd/A at 8.1 V) for BPBAPE[CB-104] and 1.82 lm/W (3.93 cd/A at 6.8 V) for BTPPA [CB-105B] at 10 mA/cm². The BPBAPE [CB-104] and BTPPA [CB-105B] devices exhibited sky blue emission (0.195, 0.303) and deep blue emission (0.159, 0.135) at 10mA/cm² respectively. We also synthesized new kinds of blue materials such as CB-201, 202, and 203. CB-203 device showed 3.11cd/A of current efficiency and (0.148, 0.088) CIE value.
