By combining tetraphenylethylene and anthracene, we synthesized 9,10-bis(4-(1,2,2-triphenylvinyl)phenyl)anthracene [BTPPA] and 1,2-di(4’-tert-butylphenyl)-1,2-bis(4’-(anthracene-9-yl)phenyl)ethene [BPBAPE]; both BTPPA and BPBAPE have similar band-gaps, however their PL spectra were shifted by about 30 nm with respect to each other. The fabricated multilayered non-doped OLED devices based on pure BTPPA or BPBAPE exhibited luminance efficiencies of 3.93 cd/A at 6.8 V and 10.33 cd/A at 8.1 V, respectively, at 10 mA/cm2. As the BPBAPE content of the emitting layer increased, the luminance efficiency of the device increased; in addition, the CIE coordinates of the fabricated devices shifted gradually from deep-blue for pure BTPPA to sky-blue for pure BPBAPE.
