TB-1,6P-TB, TB-1,8P-TB, and TB-4,9P-TB were synthesized by boration, bromination, and Suzuki aryl-aryl coupling. Optical properties were examined by UV-Vis. absorption spectra and PL spectra. The UV-Vis. absorption spectra of TB-1,6P-TB, TB-1,8P-TB, and TB-4,9P-TB showed maximum absorption wavelength of 373, 373, and 358 nm in film states. The PL spectra of TB-1,6P-TB, TB-1,8P-TB, and TB-4,9P-TB showed maximum emission wavelengths of 461, 461, and 428 nm in film states. A non-doped OLED was fabricated using the synthesized material as an emitting material. TB-1,6P-TB, TB-1,8P-TB, and TB-4,9P-TB exhibited current efficiency of 4.19, 5.16, and 2.06 cd/A. |
