Femtosecond Laser Beam

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.

Organometallic dendrimers and its applications have been introduced. Bis((4-(phenylethynyl)phenyl)ethynyl)bis-(tributylphosphine)platinum(II) with dendritic acetonide end groups have been synthesised by the divergent method. 1,3,5-benzyl(4-ethynyl(phenylethynyl))-trans-[Ru(dppe)2]ethynyl-3,5-phenyl{4-ethynyl(phenylethynyl)-trans-[Ru(4-(phenylethynyl))(dppe)2]}2)3 with nine dialkynylruthenium centers have been synthesised by convergent method. Optical power limiting measurements performed at 532 nm show that the OPL properties improve with increasing size of the dendritic substituent. Z-scan measurements carried out at different pulse-repetition frequencies show that the two-photon absorption cross-section is 10 GM. Significant increase in NLO properties seen on generation increase is maintained when the coefficients are scaled by the number of metal atoms, the dendrimer molecular weights, or hyperpolarizability (π-delocalizable electrons) in the dendritic structures. Nonlinear optical (NLO) properties are required for various applications, including the processing of optical signals, optical data storage, nanophotonics, and biophotonics.

Charge Transfer Reactions

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.
