Abstract:

A novel multibranched chromophore containing carbazole moiety，4, 4´, 4´´-tris(9-carbazyl-trans-styryl) triphenylamine (TCSTPA)，was synthesized and characterized by 1HNMR and elemental analysis. A larger two-photon absorption (TPA) cross section of the chromophore was obtained as high as 2350 GM compared to that of the traditional linear chromophore when pumped by a femtosecond laser at 800 nm. Microstructure based on TPA induced polymerization with a spatial resolution of submicron was fabricated under much lower incident laser power using TCSTPA as a TPA photoinitiator and a multifunctional resin of pentaerythritol triacrylate (PETA) as a polymerizable monomer. The result indicates potential applications of this kind of chromophores with multibranched structural motif in the fabrication of polymer and functional microdevices.

Abstract:

Two new symmetrical two-photon free-radical photopolymerization initiators, 1,4-bis-{2-[4-(2-pyridin-4-ylvinyl)phenyl]vinyl}-2,5-bisdimethoxybenzene 6 and 1,4-bis-{2-[4-(2-pyridin-4-ylvinyl)phenyl]vinyl}-2,5-bisdodecyloxybenzene 7, were synthesized using an efficient Wittig and Pd-catalyzed Heck coupling methodology. One-photon fluorescence, one-photon fluorescence quantum yields, one-photon fluorescence lifetimes, and two-photon fluorescence have been investigated. Experimental results show that both compounds were good two-photon absorbing chromophores and effective two-photon photopolymerization initiators. Two-photon polymerization microfabrication experiments have been studied and the possible photopolymerization mechanism is discussed.

Abstract:

Two symmetrical TPA chromophores containing 1,3,4-oxadiazole group were designed and synthesized through the Wittig–Horner reaction. All compounds were characterized by NMR, IR, UV and melting point. Chromophore I and II showed good thermal stability and did lose less than 5% weight on heating to about 300°C. The electrochemical property was explored by cyclic voltammetry. The HOMO and LUMO energy of compound I were estimated to be -3.65 eV and -1.09 eV. That of compound II were -3.69 eV and -1.10 eV. Both chromophores exhibited a positive solvatochromic behavior. In CH2Cl2 , the maximum peaks of single-photon-excited fluorescence (SPEF) were at 512 nm for compound I and at 495 nm for compound II with high fluorescence quantum yields 0.73 and 0.70, respectively. The two-photon-excited fluorescence (TPEF) had also been investigated. Pumped by femtosecond laser at 800 nm, strong up-conversion emissions with the central wavelength were at 532 nm for compound I and 550 nm for compound II in the solution of CH2Cl2 .

Abstract:

New organic "donor–donor" bis-stilbenyl conjugated chromophores arranged in increasing dimensionality (1D to 3D) have been synthesized in high yields by multiple Heck coupling. The central core is based on a biphenyl, triphenylenyl or spiro-bifluorenyl group when the donor part at each extremity is based on a 3,4,5-tridodecyloxyphenyl group that ensures a high solubility in organic solvents and favors the catalytic coupling reactions. Femtosecond two-photon absorption measurements in solution have evidenced improved two-photon absorption cross-sections (≅ 10-19 cm 4/ GW ) that depend on the arrangement of the chromophores.

Abstract:

The three organic two-photon-absorbing cycloalkanone chromophores 2,4-bis[4-(diethylamino)benzylidene]cyclobutanone, C26H32N2O (I), 2,5-bis[4-(diethylamino)benzylidene]cyclopentanone, C27H34N2O (II), and 2,6-bis[4-(diethylamino)benzylidene]cyclohexanone, C28H36N2O (III), were obtained by a reaction between 4-(diethylamino)benzaldehyde and the corresponding cycloalkanone and were characterized by single-crystal X-ray diffraction studies, as well as density functional theory (DFT) quantum-chemical calculations. Molecules of this series have three main fragments, i.e. central acceptor (A) and two terminal donors (D 1 and D 2) and represent examples of the D 1–π–A–π–D 2 molecular design. All three compounds crystallize with two crystallographically independent molecules in the asymmetric unit (A and B) and are distinguished by the conformations of both the molecular Et2N—C6H4—C=C—C(=O)—C=C—C6H4—NEt2 backbone (arcuate or linear) and the terminal diethylamino substituents (syn- or antiperiplanar to the plane of the molecule). The central four- and five-membered rings in I and II are almost planar, and the six-membered ring in III adopts a sofa conformation. In the crystals of I–III, the two independent molecules A and B form hydrogen-bonded [A...B] dimers via intermolecular C—H...O hydrogen bonds. Furthermore, the [A...B] dimers in I are bound by intermolecular C—H...O hydrogen bonds into two-tier puckered layers, whereas in the crystals of II and III, the [A...B] dimers are stacked along the c and a axes, respectively. Taking into account the decreasing steric strain upon expanding the central ring, compound I might be more efficient as a two-photon absorption chromophore than compounds II and III, which corresponds to the results of spectroscopic studies.

Abstract:

One current limitation of two-photon technology is the lack of optimized fluorochromes for Two-Photon Laser Scanning Microscopy (TPLSM). Recently, Albota et al. (1998) have reported the design and synthesis of a number of bis(styryl)benzene derivatives that have large fluorescence quantum yields and greater two-photon absoption cross sections than any of fluorochromes that are currently used for TPLSM. As a first step in understanding how such molecules could be used in biological experiments, we have tagged a donor-πdonor molecule with biotin. We have successfully used this dye to detect quail nuclei in 2- 4 day old fixed embryos that have been reacted with QCPN, a quail specific monoclonal antibody. We have observed that this molecule gives a very intense signal, among the most intense signals we have been able to measure in our immunoassay. In particular, the brightness was about a factor of four higher than Rhodamine B-labelled streptavidin (containing 3.3 moles of dye per streptavidin tetramer).

Abstract:

The S1 and S2 excited states of gas-phase protonated Schiff base retinal chromophores in the one- and two-photon absorptions (TPAs) are investigated with time-dependent density functional theory. In one-photon absorption, the two-dimensional (2D) site and three-dimensional (3D) cube representations reveal that S1 and S2 excited states of gas-phase protonated Schiff base retinal chromophores are all charge transfer excited states. To better study the weak S2 excited states of gas-phase protonated Schiff base retinal chromophores, we investigated theoretically excited state properties of them in TPA. For 11-cis dimethyl retinal, it is found that the cross section of S2 excited state is 51.04 GM in PTA, which is only slightly smaller than that of S1 (77.04 GM) in TPA. Therefore, the S2 excited state of 11-cis dimethyl retinal can be clearly observed in TPA experiment. The 2D site and 3D cube representations reveal that electronic transition from S1 to S2 excited state of gas-phase protonated Schiff base retinal chromophores in TPA are also of charge transfer character.

Abstract:

The photophysical and two-photon absorption (TPA) properties of three homologous quadrupolar and one related three-branched chromophores were investigated. Design of the quadrupoles is based on the symmetrical functionalization of a biphenyl core. Modulation of the nonlinear absorptivity/transparency/photostability trade-off can be achieved by playing with the twist angle of the core and on the spacers (phenylene-vinylene versus phenylene-ethynylene). The quadrupolar chromophores combine high TPA cross-sections, high fluorescence quantum yield and solvent sensitive photoluminescence properties. The branched structure exhibits spectrally broadened TPA in the NIR region (up to 3660 GM at 740 nm measured in the femtosecond regime) but reduced sensitivity to the environment.
