介绍了利用飞秒开放孔径Z扫描方法测量的可见光波长（最长可达400 nm）处有分支的π-共轭碳氢化合物的双光子吸收特性。苯乙炔基取代的苯的烃类显示出中等（几百GM）或非常大（~ 20，000 GM）的双光子吸收截面，这表明这样的烃类在波长区域中可以是有效的双光子吸收发色团。
The two-photon absorption properties of brunched π-conjugated hydrocarbons at visible wavelengths, up to 400 nm measured by using the femtosecond open-aperture Z-scan method are presented. The hydrocarbons, phenylethynylsubstituted benzenes, shows moderate (several hundreds GM) or very large (~20,000 GM) two-photon absorption cross sections, suggesting such a hydrocarbons can be efficient two-photon absorption chromophores in the wavelength region.
