Luminescence Tuning and White‐Light Emission of Co‐doped Ln–Cd–Organic Frameworks
Authors: Ablet Ayjamal , Li Shu‐Mu , Cao Wei , Zheng Xiang‐Jun , Wong Wing‐Tak , Jin Lin‐Pei 
Published: October 2012

AbstractFour new three‐dimensional isostructural lanthanide–cadmium metal–organic frameworks (Ln–Cd MOFs), [LnCd2(imdc)2(Ac)(H2O)2]⋅H2O (Ln=Pr (1), Eu (2), Gd (3), and Tb (4); H3imdc=4,5‐imidazoledicarboxylic acid; Ac=acetate), have been synthesized under hydrothermal conditions and characterized by IR, elemental analyses, inductively coupled plasma (ICP) analysis, and X‐ray diffraction. Single‐crystal X‐ray diffraction shows that two LnIII ions are surrounded by four CdII ions to form a heteronuclear building block. The blocks are further linked to form 3D Ln–Cd MOFs by the bridging imdc3− ligand. Furthermore, the left‐ and right‐handed helices array alternatively in the lattice. Eu–Cd and Tb–Cd MOFs can emit characteristic red light with the EuIII ion and green light with the TbIII ion, respectively, while both Gd–Cd and Pr–Cd MOFs generate blue emission when they are excited. Different concentrations of Eu3+ and Tb3+ ions were co‐doped into Gd–Cd/Pr–Cd MOFs, and tunable luminescence from yellow to white was achieved. White‐light emission was obtained successfully by adjusting the excitation wavelength or the co‐doping ratio of the co‐doped Gd–Cd and Pr–Cd MOFs. These results show that the relative emission intensity of white light for Gd–Cd:Eu3+,Tb3+ MOFs is stronger than that of Pr–Cd:Eu3+,Tb3+ MOFs, which implies that the Gd complex is a better matrix than the Pr complex to obtain white‐light emission materials.
The effect of a 94 GHz electromagnetic field on neuronal microtubules
Authors: Samsonov Andrey , Popov Sergey V. 
Published: October 2012

AbstractHardware that generates electromagnetic waves with wavelengths from 1 to 10 mm (millimeter waves, “MMW”) is being used in a variety of applications, including high‐speed data communication and medical devices. This raises both practical and fundamental issues concerning the interaction of MMW electromagnetic fields (EMF) with biological tissues. A 94 GHz EMF is of particular interest because a number of applications, such as active denial systems, rely on this specific frequency. Most of the energy associated with MMW radiation is absorbed in the skin and, for a 94 GHz field, the power penetration depth is shallow (≈0.4 mm). At sufficiently high energies, skin heating is expected to activate thermal pain receptors, leading to the perception of pain. In addition to this “thermal” mechanism of action, a number of “non‐thermal” effects of MMW fields have been previously reported. Here, we investigated the influence of a 94 GHz EMF on the assembly/disassembly of neuronal microtubules inXenopusspinal cord neurons. We reasoned that since microtubule array is regulated by a large number of intracellular signaling cascades, it may serve as an exquisitely sensitive reporter for the biochemical status of neuronal cytoplasm. We found that exposure to 94 GHz radiation increases the rate of microtubule assembly and that this effect can be entirely accounted for by the rapid EMF‐elicited temperature jump. Our data are consistent with the notion that the cellular effects of a 94 GHz EMF are mediated entirely by cell heating. Bioelectromagnetics 34:133–144, 2013. © 2012 Wiley Periodicals, Inc.
Photocurrent generation by helical peptide monolayers integrating light harvesting and charge‐transport functions
Authors: Moritoh Ryosuke , Morita Tomoyuki , Kimura Shunsaku 
Published: October 2012

AbstractIn this study, we construct photoenergy‐conversion systems with chromophores located with molecular precision to facilitate efficient light harvesting and charge transport. 310‐Helical peptides carrying a disulfide group at the N‐terminal, linearly arranged six naphthyl groups at the side chains, and an energy acceptor (anthryl, pyrenyl, or N‐ethylcarbazolyl group) at the C‐terminal were immobilized on a gold surface via a gold‐sulfur linkage to form a well‐defined self‐assembled monolayer with vertical orientation. The monolayer composed of helical peptides terminated with a naphthyl group instead of an energy acceptor was used as control. Upon photoexcitation of the naphthyl groups of the monolayers in solutions containing an electron donor, all the monolayers generated an anodic photocurrent. The photocurrent generation by the monolayers with an acceptor is composed of the following three steps: (1) photon capture by the side‐chain naphthyl groups and energy transfer to the terminal acceptor (light harvesting), (2) electron donation from the aqueous donor to the excited acceptor (electron generation), and (3) electron transport from the terminal to gold via the side‐chain naphthyl groups (electron hopping). Unfortunately, it was found that introduction of an energy acceptor facilitates the light‐harvesting step but suppresses the electron‐generation and electron‐hopping steps, resulting in slight reduction of the efficiency of photocurrent generation compared to the control system. Further detailed discussion on photoenergy and electron transport processes shows a prospect to realize efficient photocurrent generation systems taking advantages of both light harvesting and charge‐transport functions in future. © 2012 Wiley Periodicals, Inc.

Synthesis and properties of peptide dendrimers containing fluorescent and branched amino acids
Authors: Kitamatsu Mizuki , Kitabatake Mayumi , Noutoshi Yoshiteru , Ohtsuki Takashi 
Published: October 2012

AbstractIn this report, we describe dendritic peptides possessing central fluorescent amino acids with adjacent branched amino acids. These fluorescent‐peptide dendrimers were prepared using (9‐fluorenyl)methoxycarbonyl (Fmoc)‐based solid‐phase peptide synthesis and Fmoc‐derivative fluorescent and branched amino acids. The branched amino acids featured multiple carboxylic acids in their side chains, making the fluorescent‐peptide dendrimers highly water‐soluble compared with the analogous peptides containing the fluorescent amino acids only. The branched amino acid units also improved the fluorescence intensity of the dendrimers. Based on high‐pressure liquid chromatography and fluorescence spectroscopy results, we determined that the fluorescent groups were located in the core and that the carboxylic acids were located on the surface of the dendrimers. Fluorescence resonance energy transfer was achieved among the three proximal fluorescent groups in one of the fabricated fluorescent‐peptide dendrimers. © 2012 Wiley Periodicals, Inc.

Increased Humoral Immune Responses of Pigs to Foot‐and‐Mouth Disease Vaccine Supplemented with Ginseng Stem and Leaf Saponins
Authors: Li Yutao , Xie Feng , Chen Jian , Fan Qing , Zhai Lijuan , Hu Songhua 
Published: October 2012

AbstractVaccination is a conventional approach against foot‐and‐mouth disease (FMD) in pigs. However, failure to elicit an immune response to vaccine has been reported. Our previous investigation showed that ginseng stem and leaf saponins (GSLS) and mineral oil acted synergistically to promote Th1/Th2 immune responses to FMD vaccine in mice. This study was designed to i) find the optimal doses of GSLS in oil‐emulsified FMD vaccines to induce immune responses in mice and pigs and ii) to evaluate the effect of oil‐emulsified FMD vaccine supplemented with GSLS on the immune responses in pigs, by measuring the serum indirect hemagglutination (IHA) titer and IgG and IgG subclass levels. The GSLS‐enhanced immune response to FMD oil‐emulsion vaccine depended on the dose of GSLS added to the vaccine. Addition of GSLS at a dose of 40 μg to 2 ml of FMD oil‐emulsified vaccine significantly enhanced the humoral immune responses in pigs, when compared to the vaccine without GSLS (P<0.05). The increased antibodies included IgG1 and IgG2. Hence, GSLS and oil adjuvant synergistically promoted the immune responses to vaccination against FMD in pigs, and GSLS could be a promising vaccine additive to improve oil‐emulsified veterinary vaccines.

Published: October 2012

AbstractA Ru‐catalyzed hydrogen transfer from 2‐propanol to acetophenone in the presence of the strong base KOtBu afforded 1‐phenyl alcohol in >99 % yield within 5 min under microwave irradiation; no reaction occurred in the absence of the base. A series of catalysts was then prepared in situ from [RuCl2‐η6‐p‐cymene]2 and xantphos family ligands, which were characterized by having natural bite angles ranging from 102.2 to 137.9°. The Ru(xantphos)arene catalyst was used for various substrates to give yields and turnover frequencies between 48 and 99 % and between ≥1431 and 2982 h−1, respectively, for acetophenone derivatives and >99 % and ≥2982 h−1 for sterically bulky ketones (benzophenone, 9H‐fluoren‐9‐one, and α‐tetralone).

Published: October 2012

AbstractLiquid crystals are ordered soft materials formed by self‐organized molecules and can potentially be used as new functional materials for electron‐, ion‐ or molecular‐transport; optical; and bio‐active materials. In particular, the columnar liquid crystals are promising candidates used in various optical and electronic devices. For this purpose, design and synthesis of unconventional materials are essential. In this review, we have summarized several approaches for the synthesis of columnar liquid crystals composed of various heterocyclic systems. We also outline their liquid crystalline and other relevant properties, and their suitability for applications in diverse fields.
Detection of Metal Ions (Cu2+, Hg2+) and Cocaine by Using Ligation DNAzyme Machinery
Authors: Wang Fuan , Orbach Ron , Willner Itamar 
Published: October 2012

AbstractThe Cu2+‐dependent ligation DNAzyme is implemented as a biocatalyst for the colorimetric or chemiluminescence detection of Cu2+ ions, Hg2+ ions, or cocaine. These sensing platforms are based on the structural tailoring of the sequence of the Cu2+‐dependent ligation DNAzyme for specific analytes. The tethering of a subunit of the hemin/G‐quadruplex DNAzyme to the ligation DNAzyme sequence, and the incorporation of an imidazole‐functionalized nucleic‐acid sequence, which acts as a co‐substrate for the ligation DNAzyme that is tethered to the complementary hemin/G‐quadruplex subunit. In the presence of different analytes, Cu2+ ions, Hg2+ ions, or cocaine, the pretailored Cu2+‐dependent ligation DNAzyme sequence stimulates the respective ligation process by combining the imidazole‐functionalized co‐substrate with the ligation DNAzyme sequence. These reactions lead to the self‐assembly of stable hemin/G‐quadruplex DNAzyme nanostructures that enable the colorimetric analysis of the substrate through the DNAzyme‐catalyzed oxidation of 2,2′‐azinobis(3‐ethylbenzothiazoline‐6‐sulfonic acid), ABTS2−, by H2O2 into the colored product ABTS.−, or the chemiluminescence detection of the substrate through the DNAzyme‐catalyzed oxidation of luminol by H2O2. The detection limits for the sensing of Cu2+ ions, Hg2+ ions, and cocaine correspond to 1 nM, 10 nM and 2.5 μM, respectively. These different sensing platforms also reveal impressive selectivities.
Experimental Study of Hydrogen Bonding Potentially Stabilizing the 5′‐Deoxyadenosyl Radical from Coenzyme B12

Published: October 2012

AbstractCoenzyme B12 can assist radical enzymes that accomplish the vicinal interchange of a hydrogen atom with a functional group. It has been proposed that the CoC bond homolysis of coenzyme B12 to cob(II)alamin and the 5′‐deoxyadenosyl radical is aided by hydrogen bonding of the corrin C19H to the 3′‐O of the ribose moiety of the incipient 5′‐deoxyadenosyl radical, which is stabilized by 30 kJ mol−1 (B. Durbeej et al., Chem. Eur. J. 2009, 15, 8578–8585). The diastereoisomers (R)‐ and (S)‐2,3‐dihydroxypropylcobalamin were used as models for coenzyme B12. A downfield shift of the NMR signal for the C19H proton was observed for the (R)‐isomer (δ=4.45 versus 4.01 ppm for the (S)‐isomer) and can be ascribed to an intramolecular hydrogen bond between the C19H and the oxygen of CHOH. Crystal structures of (R)‐ and (S)‐2,3‐dihydroxypropylcobalamin showed C19H⋅⋅⋅O distances of 3.214(7) Å (R‐isomer) and 3.281(11) Å (S‐isomer), which suggest weak hydrogen‐bond interactions (−ΔG<6 kJ mol−1) between the CHOH of the dihydroxypropyl ligand and the C19H. Exchange of the C19H, which is dependent on the cobalt redox state, was investigated with cob(I)alamin, cob(II)alamin, and cob(III)alamin by using NMR spectroscopy to monitor the uptake of deuterium from deuterated water in the pH range 3–11. No exchange was found for any of the cobalt oxidation states. 3′,5′‐Dideoxyadenosylcobalamin, but not the 2′,5′‐isomer, was found to act as a coenzyme for glutamate mutase, with a 15‐fold lower kcat/KM than 5′‐deoxyadenosylcobalamin. This indicates that stabilization of the 5′‐deoxyadenosyl radical by a hydrogen bond that involves the C19H and the 3′‐OH group of the cofactor is, at most, 7 kJ mol−1 (−ΔG). Examination of the crystal structure of glutamate mutase revealed additional stabilizing factors: hydrogen bonds between both the 2′‐OH and 3′‐OH groups and glutamate 330. The actual strength of a hydrogen bond between the C19H and the 3′‐O of the ribose moiety of the 5′‐deoxyadenosyl group is concluded not to exceed 6 kJ mol−1 (−ΔG).
Rh‐Catalyzed CC Cleavage of Benzyl/Allylic Alcohols to Produce Benzyl/Allylic Amines or other Alcohols by Nucleophilic Addition of Intermediate Rhodacycles to Aldehydes and Imines

Published: October 2012

AbstractWe report three transformations: 1) direct transformation from biarylmethanols into biarylmethylamines; 2) direct transformation from one biarylmethanol into another biarylmethanol; 3) direct transformation from allylic alcohols into allylic amines. These transformations are based on pyridyl‐directed Rh‐catalyzed CC bond cleavage of secondary alcohols and subsequent addition to CX (X=N or O) double bonds. The reaction conditions are simple and no additive is required. The driving force of CC bond cleavage is the formation of the stable rhodacycle intermediate. Other directing groups, such as the pyrazolyl group, can also be used although it is not as efficient as the pyridyl group. We carried out in‐depth investigations for transformation 1 and found that: 1) the substrate scope was broad and electron‐rich alcohols and electron‐deficient imines are more efficient; 2) as the leaving group, aldehyde had no significant impact on either the CC bond cleavage or the whole transformation; 3) mechanistic studies (intermediate isolation, in situ NMR spectroscopic studies, competing reactions, isotopic labeling experiments) implied that: i) The CC cleavage was very efficient under these conditions; ii) there is an equilibrium between the rhodacycle intermediate and the protonated byproduct phenylpyridine; iii) the addition step of the rhodacycle intermediate to imines was slower than the CC cleavage and the equilibrium between the rhodacycle and phenylpyridine; iv) the whole transformation was a combination of two sequences of CC cleavage/nucleophilic addition and CC cleavage/protonation/CH activation/nucleophilic addition, with the latter being perhaps the main pathway. We also demonstrated the first example of cleavage of an C(alkenyl)C(benzyl) bond. These transformations showed the exchange (or substitution) of the alcohol group with either an amine or another alcohol group. Like the “group transplant”, this method offers a new concept that can be used to directly synthesize the desired products from other chemicals through reorganization of carbon skeletons.
3 D MOFs Containing Trigonal Bipyramidal Ln5 Clusters as Nodes: Large Magnetocaloric Effect and Slow Magnetic Relaxation Behavior
Authors: Shi Peng‐Fei , Zheng Yan‐Zhen , Zhao Xiao‐Qing , Xiong Gang , Zhao Bin , Wan Fan‐Fan , Cheng Peng 
Published: October 2012

AbstractTwo 3D heterometal–organic frameworks based on infrequent trigonal bipyramidal Ln5 clusters as nodes were structurally and magnetically characterized (Ln=Gd (1), Dy (2)). The results indicate large MCE of up to 30.7 J kg−1 K−1 in 1 and slow magnetic relaxation behavior in 2. Expectedly, constructing 3D MOFs based on multinuclear clusters as nodes may will be a new strategy for achieving large −ΔSm. Additionally, compound 1 exhibits high thermal and solvent stabilities, providing a favorable foundation for realistic applications.
Optical Properties and Photo‐Oxidation of Tetraphenylethene‐Based Fluorophores
Authors: Aldred Matthew P. , Li Chong , Zhu Ming‐Qiang 
Published: October 2012

AbstractWe report the optical properties of tetraphenylethene (TPE) and other TPE derivatives functionalised with an octyl group (TPE‐OCT) and polyethyleneglycol group (TPE‐PEG) in the side chain. We compared TPE‐OCT and TPE‐PEG with TPE in both organic solvents and under aqueous conditions. All materials exhibit aggregation‐induced emission, however, uncommonly, TPE‐PEG seems to aggregate in aqueous solution with enhanced photoluminescence quantum efficiency (PLQE) relative to that in organic solvents. All three materials can be photo‐oxidised in solution to their diphenylphenanthrene derivative by irradiation with UV light (at both ≈1 and ≈5 mW cm−2), with a subsequent enhancement in PL efficiency. The electron‐donating ether group increases the rate of oxidation relative to bare TPE and also photo‐oxidation was shown to be solvent and concentration dependent. Finally, photo‐oxidation was also demonstrated in the aggregate state.
