Abstract

We synthesized new bluish-green and sky-blue emitting materials, 1, 1, 2, 2-tetrakis (4′-tert- butylbiphenyl) ethane [TBBPE] and 1, 1, 2, 2-tetrakis (4-(anthracen-9-yl) phenyl) ethene [TAPE]. TBBPE and TAPE film showed PL maximum value of 511 nm and 492 nm. TBBPE OLED device showed bluish-green CIE value of (0.236, 0.412) and high luminance efficiency of 5.02 cd/A at 10 mA/cm2. TAPE device also showed sky-blue CIE value of ( ...
