A novel multibranched nonlinear dye，4, 4´, 4´´-tris(9-carbazyl-trans-styryl) triphenylamine (TCSTPA)，has been designed and synthesized aimed at two-photon absorption applications. Two-photon absorption cross section of the multibranched dye was obtained as high as 2.35×10-47cm4s photon-1molecule-1pumped with femtosecond laser beam at 800 nm. One-photon and two-photon absorption optical properties were demonstrated in solutions. Three-dimensional (3D) optical data storage experiments were carried out by two-photon photobleaching in the multibranched-dye doped polymethylmethacryate (PMMA) with a 3D data storage density of approximate 14 Gbits/cm3. Research on the two-photon photobleaching ability shows the novel two-photon absorption dye with multibranched molecular motif has higher photosensitivity than traditional linear two-photon absorption dyes do.

The intensity of two-photon induced fluorescent shows quadratic dependency to the excitation intensity, as a result, one can achieve optical sectioning in fluorescent microscopy without the use of a confocal aperture. When the excitation power is properly adjusted, the fluorescent and photobleached volume is restricted to the vicinity of the focal points; therefore, it is possible to use this mechanism to achieve 3D data storage and microstructure fabrication (stereolithography).The recording medium used in this experiment was poly-HEMA block doped with a high efficient two-photon fluorophore, APSS, (4-[N-(2-hydroxyethyl)-N-methyl) amino phenyl]-4’-(6-hydroxyhexyl sulfonyl) stilbene). The block was made by dissolving APSS in HEMA with an initiator, 2,2’-azobisisobutyronitril (AiBN) (1% mole ratio) and polymerized at 60° C for 48 hours. The polymer was then trimmed into a small rectangular block (3×5×1 mm3) and surfaced by using a ultramicrotome with a glass knife. A modified Biorad MC500 LSM equipped with a home-made computer controlled stage scanner was used for both writing (stage scanning) and read-back (beam scanning).

AbstractMolecules exhibiting strong two-photon absorption hold great potential for a wide range of applications including two-photon fluorescence imaging, three-dimensional (3D) optical data storage, and 3D microfabrication. We have observed two-photon absorptivities as high as 1500×10− 50 cm4 s/photon in bis-donor diphenylpolyene derivatives that are correlated to simultaneous charge transfer from the end groups to the polyene bridge in the molecule. Many of these molecules are also excellent photoexcitable electron donors that can initiate charge-transfer reactions with acrylate monomers. Marcus theory is used to describe the efficiency of these charge-transfer reactions. Polymerization rates have also been measured and we show that these twophoton chromophores display increased sensitivity and recording speed over conventional UV photo-initiators. The fabrication of complex, three-dimensional structures by twophoton polymerization is demonstrated and discussed in the context of advanced photonic applications.
