| 英文摘要 | A series of novel asymmetrical fused compounds containing the backbone of fluorene[2,3-b]benzo[d]thiophene (fbt) were effectively synthesized and fully characterized. single-crystal x-ray studies demonstrated that the length of the substituent side chains greatly affects the solid-state packing of the obtained fused compounds. dft, photophysical, and electrochemical studies all showed that the fbts have large band gaps, low-lying homo energy levels, and therefore good stability toward oxidation. moreover, the substituents strongly influence the fluorescence properties of the resulting fbt derivatives. the di-n-hexyl compound exhibits intense fluorescence in solution with the highest quantum yield of up to 91%. solution-processed green phosphorescent organic light-emitting diodes with the di-n-butyl derivative as the host material exhibited a maximum brightness of 14.185 cd m(-2) and a luminescence efficiency of 12 cd a(-1). |
