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.
