Abstract

6,6-(9H-fluoren-9,9-diyl)bis(2,3-bis(9,9-dihexyl-9H-fluoren-2-yl)quinoxaline) (BFLBBFLYQ) was a novel small molecular fluorene material with fluorescence maxima at 450 nm in spin cast films. Compared to spin cast films, BFLBBFLYQ vacuum evaporated deposition films exhibited different photo-physical properties. The low energy emission bands from 530 to 570 nm were observed from the electroluminescence (EL) and photoluminescence (PL) spectra of BFLBBFLYQ films evaporated deposition in ultrahigh vacuum circumstance, and the origin of these emission features were investigated and discussed. Also, the emissive properties of BFLBBFLYQ spin cast films upon thermal annealing and under UV irradiation in air were characterized for the effect of thermal oxidization and photo-oxidization.
