中文摘要：

这封信在一个光子和汗衫氧的二光子的吸收产生上报导分支的影响和 photosensitizers 的溴替换。在红外线附近的 femtosecond Ti:squassier 激光被利用决定在 20 nm 的间隔从 700 ～ 880 nm 调节波长的 photosensitizers 的二光子的性质。一个光子并且二光子光并且 photosensitizers 的 photophysical 性质在分支和代替的溴原子上显示出重要依赖。

英文摘要：

This letter reports the influence of branches and bromine substitution of the photosensitizers on one- and two-photon absorption generation of singlet oxygen. Near-infrared femtosecond Ti：squassier laser was utilized to determine two-photon properties of the photosensitizers tuning wavelength from 700 to 880 nm at intervals of 20 nm. One- and two-photon optical and photophysical properties of the photosensitizers show significant dependence on the branches and substituted bromine atoms.
