    <p>Synthesis of iron oxide nanoparticles (Fe-O NPs) from iron(III)acetylacetonate solution by femtosecond laser irradiation is reported. Fe-O NPs and carbon are agglomerated in <i>n</i>-hexane, while single-nanometer-sized dispersed Fe-O NPs are obtained in water. We propose that the choice of ligands and solvent determines the primary particle size distribution and dispersion states of NPs as well as carbon contaminants in laser-assisted synthesis using metal complexes as reactants.</p>

    芳香族フッ素化合物にフェムト秒レーザーを照射することで、芳香族化合物では最も小さい4価陽イオン(ヘキサフルオロベンゼン、C6F6)を生成することに成功しました。イオンの検出には飛行時間型質量分析計を用い、イオンの飛行時間からイオンのm/zを決定しました。さらに、同位体ピークの面積比から元素組成を決定しました。このような多価陽イオンを生成することができた理由として、フェムト秒レーザーを用いるトンネルイオン化によって生じるイオンが余剰なエネルギーをもたないこと、プロトンとして容易に脱離する水素原子をフッ素原子で置換したことが挙げられます。今回、フェムト秒レーザーを用いることで芳香族4価陽イオンについて分子サイズの最小値を34年ぶりに更新しました。その一方で、リフレクトロンを用いて、4価ヘキサフルオロベンゼンの寿命の下限値を9マイクロ秒と見積もりました。ヘキサフルオロベンゼンについては、高速イオン選別器を用いて価数別にイオンを選別し、解離で生じる生成物をリフレクトロンによって分離する事で価数ごとの反応の観測を試みました。しかしながら、検出感度を限界まで上げても生成物は観測されませんでした。多価陽イオンが単独では極めて安定であることが明らかになりましたので、これまで未知であった多価陽イオンの物性や反応の研究が可能であるといえます。また、多価陽イオンのサイズが十分に小さくなったため理論研究にも取り組みやくなったといえます。これらの課題については、引き続き研究を進めていくつもりです。(参照: LINK1)

    We briefly review femtosecond laser induced chemical reactions and nanomaterial productions in aliquid phase. Focused intense femtosecond laser pulses create a high density of reactive species such assolvated electrons and cation radicals of the solvent. The solvated electrons efficiently reduce the metalions followed by their nanoparticle formations. Multimetallic nanoparticles, which are expected to beutilized as electromagnetic materials and catalysts, are produced. In the cases of neat organic solvents,polyynes and carbon nanoparticles are formed. We also presented the production of heteroatom-dopedcarbon nanoparticles, which are candidates of oxygen reduction catalysts in fuel cells. By using aqueousorganic solutions and/or water/organic bilayer solutions, hydrophilic carbon nanoparticles are formed bythe successive oxidation of organic molecules by hydroxyl radicals. Nanoparticle synthesis by reactivespecies in the liquid phase might be an alternative means of widely used laser ablation in liquid.

    The decomposition of aqueous chlorohydrocarbons regarded as environmental pollutants has been widely studied. However, it is usually difficult to separate liquid and/or volatile products originated from chlorohydrocarbons from reactant solution. We succeeded to precipitate hydrophobic carbon nanoparticles and their agglomerates from aqueous dichloromethane by femtosecond laser (0.8 µm, 40 fs) irradiation. In the case of water/dichloromethane bilayer solution, the precipitates were produced in abundance when the water layer was exposed to femtosecond laser pulses. The time evolution of pH and transmittance revealed that the precipitation of carbon particles was preceded by dechlorination. Focusing intense femtosecond laser pulses onto water creates a high density of reactive species in a well-confined volume; i.e., plasma filament. The graphitization hence solidification by using laser pulses could be an useful way to remove chlorinated compounds from their aqueous solution.

    For the first time, femtosecond laser mass spectrometry (FLMS) has successfully detected 1, 3, 6-trichlorodibenzo-p-dioxin and 2, 2′, 5-trichlorobiphenyl. Non-chlorinated dibenzo-p-dioxin and biphenyl were also compared with the results of trichlorinated dioxins. The formation of parent ions without heavy fragmentation is an important goal for laser mass spectrometry ; in other words, a high signal intensity ratio value of the parent ions/total ions (P/T ratios) is essential. The ratios were found to depend on the laser intensities as well as the wavelengths in FLMS. Generally, dioxins were more highly fragmented with increases in the laser intensity for all compounds studied here ; the P/T ratios of non-chlorinated dioxins were higher with increases in the laser wavelength. The wavelength dependency for the chlorinated compounds was not distinct, probably because C-Cl bonds are easily dissociated in high-intensity laser fields, which induce further fragmentation. As a consequence of dissociation, the P/T ratios of the chlorinated dioxins were lower than the non-chlorinated dioxins. Within our experimental parameters, the optimum laser conditions were 1500 nm excitation with an intensity of 3.0×10^<13> W/cm^2 for 1, 3, 6-trichlorodibenzo-p-dioxin and 2000 nm and 3.3×10^<13> W/cm^2 for 2, 2′, 5-trichlorobiphenyl.

    © 2004 Elsevier B.V. All rights reserved. Pumping a molecule by a femtosecond, pulse to an electronically excited state S2 creates a vibrational wave packet in this state. Ultrafast internal conversion through a conical intersection may give rise to a periodic motion in a lower potential well, which can be observed as a coherent oscillation in pump-probe spectroscopy. If the slope on entering the well excites the vibration, its assignment gives information on the relaxation or reaction path direction. In the experiment in this chapter the molecules are excited to the S2 (La, symmetry 2A) state by a 70 fs pulse at 270 nm. The La and CT states are just two locations on one potential energy surface (PES), and the Lb PES in the form of a conical intersection (CI) crosses this surface. The wave packet passes through the CI and branches there. The one entering first into the S1 well oscillates there coherently, whereas the other arriving later from the CT state seems to have lost its coherence. The vibration is assigned in PIPBN to amino-group wagging (planarization/pyramidalization) in S1.

  • Steady-state and time-resolved fluorescence analysis for a cyanobiphenyl mesogen in polymer-dispersed liquid crystal films

    Shinji Kato, Feng Qi Chen, Tetsuya Shimada, Tomoyuki Yatsuhashi, Haruo Inoue, Chyongjin Pac

    Journal of Physical Chemistry B   104 ( 12 )   2642 - 2646   2000.03( ISSN:1520-6106

     More details

    Steady-state and time-resolved fluorescence behavior of 4-cyano-4′-pentylbiphenyl (5CB) in polymer-dispersed liquid crystal (PDLC) films sandwiched between two quartz substrates was characterized by the surfacelimited excitation (SLE) and through-film excitation (TFE) methods, which were used to discriminate the emissions from the interface layer with the substrate and from the interior domain. Although PDLC films showed both the monomer and excimer emissions of 5CB, SLE gave a substantially greater contribution of the former in the fluorescence than TFE. By contrast, a neat nematic film of 5CB showed exclusively the excimer emission independently of the excitation methods. Time-resolved analysis of the excimer emission from PDLC films revealed double-exponential decay profiles with shorter-lived (1.5-1.8 ns) and longer-lived (12-17 ns) components, in which the former is dominant for the excimer emission obtained by SLE, while the latter takes a major part for that obtained by TFE. By contrast, the excimer emission from a neat nematic film of 5CB showed a single-exponential decay with a ∼7 ns lifetime independently of the excitation methods. The unique fluorescence behavior of the PDLC films has been discussed in terms of different molecular aggregation features of 5CB in the interface layer and in the interior domain. © 2000 American Chemical Society.
