Fixation for the helical structure of a glassy cholesteric liquid crystal reflective film

引用

Journal of university of science and technology beijing 2006年第5期13卷 476-479页

作者： jiumei xiao Wanli He Jin Gao Huai Yang applied science School University of Science and Technology Beijing Beijing 100083 China Materials science and Engineering School University of Science and Technology Beijing Beijing 100083 China

The planar texture of glassy cholesteric siloxane cyclic side-chain liquid crystals was fixed by quenching initially. Then the polymer network formed by the optically active polymerizable monomers imposed additional constraints on the motion of chain segments of the glassy liquid crystal and then further stabilized the molecule arrangement. A cholesteric liquid crystal film with stable optical properties was developed by this method.

Multicolor circularly polarized phosphorescence of axially chiral binuclear platinum(Ⅱ) complexes

D-A charge transfer, including through-bond charge transfer and through-space charge transfer between two different electron donors（D） and electron acceptors（A）, is a fundamental and powerful tool to tune the optical properties of organic dyes. Herein,we demonstrate a unique strategy to tune phosphorescence and circularly polarized luminescence properties of axially chiral binuclear Pt（Ⅱ） complexes through long-range charge transfer, even though these molecules have two totally identical segments on either side of the chiral core. The presence of axial chirality would break not only the symmetry of molecular structure and π-conjugation system but also the symmetry of charge distribution for long-range charge transfer. These binaphthyl-based Pt（Ⅱ）complexes bearing coordinated atoms far away from chiral axis exhibit no Pt-Pt interactions but colorful concentrationdependent phosphorescence with quantum yield up to 86.4% and could be applied as emitters in highly efficient solutionprocessed organic light-emitting diodes to achieve luminance, luminance efficiency, power efficiency, external quantum efficiency, and asymmetry factor up to 8.94 × 10～3cd m-2. 41.9 cd A-1, 18.8 lm W-1, 12.6% and 2.98 × 10-3, respectively. Therefore,the present work affords a new and simple way to utilize the inherently asymmetric advantage of chirality for the design of D-Abased organic dyes.

Face Recognition on Partial and Holistic LBP Features

引用

Journal of Electronic science and technology 2012年第1期10卷 56-60页

作者： xiao-Rong Pu,Yi Zhou,and Rui-Yi Zhou the School of Computer science and Engineering,{2. of Electronic science and technology of china,Chengdu 611731,china The School of Computer science and Engineering.university of Electronic science and technology of china Chengdu 611731China

An algorithm for face description and recognition based on multi-resolution with multi-scale local binary pattern （multi-LBP） features is proposed. The facial image pyramid is constructed and each facial image is divided into various regions from which partial and holistic local binary patter （LBP） histograms are extracted. All LBP features of each image are concatenated to a single LBP eigenvector with different resolutions. The dimensionaUty of LBP features is then reduced by a local margin alignment （LMA） algorithm based on manifold, which can preserve the between-class variance. Support vector machine （SVM） is applied to classify facial images. Extensive experiments on ORL and CMU face databases clearly show the superiority of the proposed scheme over some existed algorithms, especially on the robustness of the method against different facial expressions and postures of the subjects.

Current transport in ZnO/Si heterostructure grown by laser molecular beam epitaxy

引用

Chinese Physics B 2012年第9期21卷 440-444页

作者：滕晓云吴艳华于威高卫傅广生 College of Physics science and technology University of Hebei University

The n-ZnO/p-Si heterojunction was fabricated by depositing high quality single crystalline aluminium-doped n-type ZnO film on p-type Si using the laser molecular beam epitaxy technique. The heterojunction exhibited a good rectifying behavior. The electrical properties of the heterojunction were investigated by means of temperature dependence current density-voltage measurements. The mechanism of the current transport was proposed based on the band structure of the heterojunction. When the applied bias V is lower than 0.15 V, the current follows the Ohmic behavior. When 0.15 V ~ V 〈 0.6 V, the transport property is dominated by diffusion or recombination in the junction space charge region, while at higher voltages （V 〉 0.6 V）, the space charge limited effect becomes the main transport mechanism. The current-voltage characteristic under illumination was also investigated. The photovoltage and the short circuit current density of the heterojunction aproached 2.0 mV and 2.10 mA/cm^2. respectively.

Studies on Electrophilic Substitution of Quasi-Aromatic Metal Ion Complexes

引用

Chemical Research in Chinese Universities 1993年第4期9卷 282-287页

作者： XIA xiao-ping, HE Hai-ying and LI Ming (Department of Chemistry, Huazhong university of {2. and technology, Wuhan, 430074)ZHAO Cheng-xue (National Laborotory of applied Organic Chemistry, Lanzhou university, Lanzhou, 730000)

The electrophilic substitution reaction occurring to the chelate ring of the complexes could be regarded as an indication of quasi-aromaticity of the ring systems, no catalyst was used and only triethylamine was employed, implying that the aroylating agents with different p-substituents are polarized enough to be effective electrophiles to attack the methine carbon of the electron-rich substrate 1. This property is probably the clue to polarization of the ligand electrons by the nickel( Ⅱ ) ion and to the participation of the nickel( Ⅱ ) in the π-bond systems of the two coordinated conjugated rings. The linearity relationship between vd-d maxima, E1/2.X(1) and σp are obtained, respectively. The electronic environment of central metal ion as well as the aromaticity of the ring system are affected by the electronic properties of the p-substituents. A comparison of the electrochemical results with each other showed .that when the electronegativity of the substituent was higher, the oxidation(Ni2./Ni3+) becomes more difficult.
