The result showed that the compounds containing CF3 had lower LUMO levels than those containing no fluoro group, but the phenyl unit containing four F groups in 1, 3, 4-oxadiazole compound had no significant effect on its photo-electric properties.

• 结果表明，与不含氟的恶二唑化合物相比，三氟甲基苯单元可降低化合物的LUMO能级，而四氟苯单元则对化合物的光学和电化学性质无显著影响。
