We have found a form of copper(II) terephthalate that occluded an enormous amount of gases such as N2, Ar, O2, and Xe. Copper(II) terephthalate is the first metal complex found capable of adsorbing gases. This complex has opened a new field of adsorbent chemistry and is recognized as a leader in the construction of microporous metal complexes. In extending the route for the synthesis of microporous complexes, we obtained many new porous materials that are widely recognized as useful materials for applications in areas such as gas storage, molecular sieves, catalysis, inclusion complexes, and surface science. 相似文献

Poly(2,7-di-n-pentyldibenzofulvene)s with no stereocenters, obtained by anionic polymerization using chiral 9-fluorenyllithium ligand complexes, showed intense circular dichroism in film form due purely to the chiral conformation of the main chain, while no chiroptical properties were detectable in solution. 相似文献

The vibrational circular dichroism (VCD) technique was applied to carbohydrates and produced a glycoside characteristic VCD band, which was named the "glycoside band." It confirmed that this vibration was related to anomeric configurations of carbohydrates in the case of the d-series by means of isotope substitution. This band is defined as a negative, sharp, and intense VCD band at around 1145 cm-1, exhibited by d-sugars with an axial alpha-glycosidic linkage in the 4C1 conformation. As applications of this band, the VCD studies of the maltose-cellobiose mixture and the monitoring of the amyloglucosidase reaction were examined. 相似文献

Exponential decay estimates are obtained for complex-valued solutions to nonlinear elliptic equations in
where the linear term is given by Schr?dinger operators H = − Δ + V with nonnegative potentials V and the nonlinear term is given by a single power with subcritical Sobolev exponent in the attractive case. We describe specific
rates of decay in terms of V, some of which are shown to be optimal. Moreover, our estimates provide a unified understanding of two distinct cases in
the available literature, namely, the vanishing potential case V = 0 and the harmonic potential case V(x) = |x|2.

We measured the time evolutions of the luminescence spectra in a quasi-1D halogen-bridged platinum complex [Pt(en)(2)][Pt(en)(2)Br(2)](ClO4)(4) with a 50 fs resolution up-conversion spectroscopy and succeeded in real-time visualization of the shape of the wave packet (WP) propagating on the adiabatic potential surface of a self-trapped exciton. The behavior of the WP is in excellent agreement with a calculation based on a harmonic oscillator. We have found that the damping of the WP oscillation is highly nonexponential. 相似文献

In this paper a new model is presented of a one-dimensional interacting particle system which we call “a clustered random walk system”, in which a tagged particle has an asymptotically Gaussian distribution with variance βt1/ (1<2). 相似文献
