测量了15个苯骈噁唑类新型荧光增白剂在N,N-二甲基甲酰胺中的光物理和光化学性能。这些化合物都具有较高的荧光量子产率(大于0.64),除了分子中含有联苯构造的以外,其余的都具有激光性能,激光转换效率在9.5～22.4％,光化学稳定性都较好,适宜用作紫外和近紫外区域的激光染料。

Photophysical and photochemical properties of fifteen benzoxazole fluorescent whitening agenta in N, N'-dimethylformamide (DMP) have been measured. Their fluorescence quantum yields were all over 0.64. Except three compounds containing biphenyl structure, the rest had laser action with laser conversion effieiencies between 9.5% and 22.4%.Photochemical stabilities of them were better and might be used as laser dyes in ultraviolet and near ultraviolet band.
