Published: May 2015

AbstractPhotoisomerization and photodissociation of toluene, xylene, 4‐methyl‐pyridine, and aniline under collision‐free conditions are reviewed. For many years, it was thought that all the isomerization of aromatic molecules could be described in terms of ring permutation. One important characteristic of ring permutation is that the atoms belonging to the alkyl or amino groups attached to the aromatic ring are not involved in the exchange with the atoms within the aromatic ring. Only the relative positions of these alkyl or amino groups are changed. However, the observation of new dissociation products from toluene, xylene, 4‐methyl‐pyridine, and aniline suggests that a small fraction of these molecules undergo another kind of isomerization prior to dissociation. This isomerization involves the exchange between six‐membered ring and seven‐membered ring structures. It provides a new pathway for aromatic molecules to undergo totally different structural change. The significance of this isomerization is that the carbon atoms (or nitrogen atom) and hydrogen atoms belonging to the alkyl group (or amino group) attached to the aromatic ring are involved in an exchange with those atoms in the aromatic ring during the isomerization. The structural change and competition between isomerization and bond dissociation are discussed.

Published: May 2015

AbstractA linear quadrupole mass spectrometer operating in the third stability region [(a, q) ≈ (3, 3)] has been developed and utilized to obtain the mass spectra of multiply charged protein ions generated by electro‐spray ionization. The spectra were acquired by scanning the frequency of the quadrupole with a home‐built wide‐band power amplifier from 400 to 100 kHz at constant voltage amplitudes in the range of 100 V. A mass resolution approaching R1/2 = 200 was achieved for doubly charged gramicidin S ions at m/z 570.5. Further improvement of the resolution is anticipated when a higher‐voltage power amplifier is available.

Published: May 2015

AbstractThree fundamental ultrafast photochemical reactions in solution, i.e., photoisomerization of cis‐stilbene, photodissociation of diphenylcyclopropenone and excited‐state intramolecular proton transfer of 10‐hydroxybenzoquinoline, were studied by two color pump‐probe spectroscopy with time‐resolution as high as 30 −; 70 fs. The coherent nuclear wavepacket motions of the excited‐states that undergo ultrafast reactions were observed, and their relevance to the reaction was discussed. It was concluded that these reactions are classified to three different types for the relation between the initial nuclear wavepacket motion and the reaction coordinate.
Aggregation of Zinc Protoporphyrin in Anodized Aluminum Oxide (AAO) Nanoporous Environments
Authors: Lin Jin‐Shyong , Chen Yu‐Chying , Chen Chien‐Chon , Diau Eric Wei‐Guang , Liu Tzeng‐Feng 
Published: May 2015

AbstractThe aggregation behavior of zinc protoporphyrin (ZnPP) inside nanoporous environments of anodized aluminum oxide (AAO) has been investigated through observation of the variation of UV/visible absorption and emission spectra of the system. The Soret band in the absorption spectrum of ZnPP/AAO thin‐film samples becomes much broader than that observed for ZnPP/THF solutions, and the relative intensity of the Q band is distinctly enhanced for the former. The broad Soret band overlaps the enhanced Q band increasingly as the degree of aggregation increases with increasing duration of immersion, with initial concentration of ZnPP/THF solutions, or with decreasing pore size of AAO nanotubes. A strong excitonic coupling between the Soret and Q transition dipoles causes the absorption spectrum of the ZnPP/AAO system to cover the entire visible spectral region. Emission spectra of ZnPP/AAO samples in the steady state contain multiple resolvable components assigned to monomer, dimer and higher aggregates. The observed systematic variation of emission spectra of ZnPP/AAO samples is consistent with the observation in absorption spectra of the system and reflects the significance of aggregation of ZnPP in a specific nanoporous environment.

Published: May 2015

AbstractOptical and magnetic properties have been investigated for the structurally confined amorphous magneto‐semiconductor, ternary chalcogenide, within the nanochannels of the mesoporous host. The structural confinement induced a weak crystallographic ordering of the magneto‐semiconductor within the nanochannels. Unique optical properties were observed for this nanocomposite, which were possibly due to the size and energy quantization of the confined guest chalcogenide within the nanochannels. The structural confinement also induced the suppression of the phonon coupling to the photoexcited carriers during the carriers' recombination process. The spin‐glass freezing temperature (Tf = 4.2 K) which was the characteristic magnetic transition temperature for the amorphous bulk was shifted to 2.3 K for the confined system, possibly due to the generation of the superparamagnetic domains induced by the quantum confinement effect.

Published: May 2015

AbstractThree simple, sensitive and accurate spectrophotometric methods have been developed for the determination of dextromethorphan hydrobromide (DEX) and ketamine hydrochloride (KET) in dosage forms. These methods are based on the formation of ion‐pair complexes with bromocresol green (BCG), bromocresol purple (BCP), and bromophenol blue (BPB) in acidic medium. The coloured ion‐pair products are measured at 419, 409 and 417 nm for DEX and at 417, 408 and 416 nm for KET using BCG, BCP and BPB, respectively. Beer's law was obeyed in the range of 2.0–22 μg mL−1 for DEX and 2.0–16 μg mL−1 for KET. The composition of the ion‐pair was established by continuous variation and molar ratio methods. The proposed methods were applied successfully for the determination of DEX and KET in dosage forms applying the standard addition technique and compared statistically with the official methods. The molar absorptivity, Sandell sensitivity, detection and quantification limits were also calculated.

Abstract2,4‐Dichlorophenoxy acetic acid herbicide is spectrophotometrically determined by diazotization method in a flow injection assembly. The method is based on base hydrolysis of herbicides. The hydrolyzed product 2,4‐dichlorophenol is reacted with diazotized sulfanilic acid. The absorbance of the resulting coloured product was measured at 480 nm. The calibration graph is linear over the range of 0.2–20 μgmL−1, with a relative standard deviation of (RSD) of 7.2% and sample throughput of 90 samples h−1. The % recovery for determination of 2,4‐dichlorophenoxy acetic acid was found to be 92.0–95.3%. The method is easy, simple and faster than the established chromatographic method. The method was applied for determination of 2,4‐dichlorophenoxy acetic acid herbicide in commercial formulations and for residue determination in fruits and food samples.

Published: May 2015

Abstract3‐(2‐Furyl)‐3‐oxopropanitrile reacts with keto and ester‐hydrazonyl chlorides to afford the corresponding acetyl‐ and ester‐pyrazole derivatives. The latter pyrazoles reacted with hydrazine and gave either the pyrazolo[3,4‐d]pyridazines or pyrazolylhydrazides. Treatment of the latter hydrazides with phenylisothiocyanate and with phenylisocyanate resulted in the formation of the pyrazolylthiadiazole and pyrazolyloxadiazole derivatives, respectively.

Carbon‐13 NMR and PM3 Study on the Substituent Effect of 1‐Aryl‐3,3‐Difluoro‐2‐Halocyclopropenes
Authors: Lee Chuan‐Chen , Yang Ya‐Jen , Lin Shaw‐Tao , Chen Li‐Chun 
Published: May 2015

AbstractThe substituent‐induced chemical shifts (SCS) of C2 and C3 on the 13C NMR spectra of 1‐aryl‐3,3‐difluoro‐2‐halocyclopropenes were studied. The correlation between SCS and Hammett constants shows that the tendency of effect by the substituents on the phenyl ring is BrC2(ρ = 4.66) > ClC2(ρ = 4.50) and ClC3(ρ = −1.63) > BrC3(ρ = −1.41). The DSP treatment further confirms the SCS of C2 and C3 are the main contribution of the resonance effect and field effect, respectively. Those results of the incremental shifts reveals that the gem‐difluorocyclopropenyl bearing the phenyl group possesses a triple bond character, which is also observed in IR spectra with high n̈C=C (1768–1945 cm−1).

AbstractCondensation of acetylacetone with 4‐methoxybenzaldehyde, 2,4‐dimethoxybenzaldehyde, 3,4‐dimethoxybenzaldehyde, 4‐nitrobenzaldehyde and 2,4‐dinitrobenzaldehyde in water and in the presence of cetyltrimethylammonium bromide (CTABr) as cationic surfactant in dilute sodium hydroxide at room temperature did not afford the expected arylideneacetylacetone but yielded 1H‐inden‐1‐one derivatives 1, while, with piperonaldehyde under the same conditions afforded dipiperonylideneacetone 2. Also 3‐acetylthiophene condensed with some aromatic aldehydes under the same conditions gave the expected stereoselective thienylpropenones 4. The structures of the products were identified by IR, NMR, Mass spectral data and elemental analysis.

Authors: Zhai Shang‐Ru , Wei Li , Qu Feng‐Zuo , Wang Shao‐Jun 
Published: May 2015

AbstractFour common mesostructured aluminosilicates (e.g. AlMCM‐41, AlMCM‐48, AlMSU‐1 and AlSBA‐15, Si/Al = 7.5) with different pore framework structures were prepared via post‐synthetic method utilizing aluminum isopropoxide as the aluminating agent and characterized by 27Al MAS NMR, XRD, N2‐adsorption isotherm and NH3‐TPD. It was found that, on the basis of the above analysis results, AlMCM‐41, AlMSU‐1 and AlSBA‐15 retained more mesoporosity than cubic Al/MCM‐48 after exposure to pure steam at 800 °C, which may be responsible for their much higher activities in bulky 1,3,5‐triisopropylbenzene (TIPB) conversion.

Authors: Bangash Fazlullah Khan , Alam Sultan 
Published: May 2015

AbstractThe effect of temperature of activation on bone charcoal, used as adsorbent for the removal of Patent Blue VF from water solutions was studied. The adsorbent was characterized by FTIR, XRD, SEM and EDS. The kinetic of adsorption of dye was carried out at 10 °C and 45 °C. Carbonization temperature (600–1000 °C) of the adsorbent has significant effect on the removal of dye from water solutions. The first order kinetic, Elovich, Bangham, parabolic diffusion and power function equations were found to fit the kinetic data. Activation energies of adsorption (Δ≠) have higher values for the charcoal activated at high temperatures and the other thermodynamic parameters like ΔH≠, ΔS≠ and ΔG≠ were also found.

Authors: Wang Chun‐Feng , Guan Xia , Li Quan‐Min , Liu Guo‐Guang 
Published: May 2015

AbstractA new method for indirect determination of captopril (CPT) with NaNO3 and NH4SCN by floatation and separation of copper has been studied. In the weak acid, a small amount of Cu(II) can be reduced to Cu(I) by CPT, then Cu(I) reacted with the SCN, which can float on the surface of the liquid phase with NaNO3. A good linear relationship is observed between the floatation yield (E%) of Cu(II) and the amount of captopril. The linear range is 2˜32 mg/L. On the ground, captopril can be indirectly determined by determining E(%) of Cu(II). The method is simple, rapid, reliable and has good selectivity. The developed method can be applied to indirect determination of captopril with satisfactory results.

Published: May 2015

AbstractA laboratory study was carried out to investigate the secondary organic aerosol (SOA) products from photooxidation of the aromatic hydrocarbon toluene. The experiments were conducted by irradiating toluene/CH3ONO/NO/air mixtures in a home‐made smog chamber. The aerosol time‐of‐flight mass spectrometer (ATOFMS) was used to measure the size and the chemical composition of individual secondary organic aerosol particles in real‐time. According to a large number of single aerosol diameters and mass spectra, we obtained the size distribution and chemical composition of SOA statistically. Expeperimental results showed that aerosol created by toluene photooxidation is predominantly in the form of fine particles, which have diameters less than 2.5 μm (i.e. PM2.5), and the predominant components of aerosol are furane, methyl glyoxylic acid, phenol, benzaldehyde, benzyl alcohol, cresol, 3‐hydroxy‐2,4‐dioxo‐pentanal, methyl nitrophenol, and 5‐hydroxy‐4,6‐dioxo‐2‐heptenal. The possible reaction mechanisms leading to these products were also discussed.

Complexes 1a, 1b, 2a, and 2b have been characterized by NMR spectroscopy and by X‐ray crystallography. Complexes 1a and 2a have shown moderate reactivity for 1‐hexene polymerization in the presence of MAO.

Published: May 2015

AbstractOne cuprous complex [Cu(L)(PPh3)I] was obtained by reaction of [Cu(PPh3)3I] (PPh3 = triphenyl‐phosphine) with a new α‐diimine ligand L (N‐diphenylmethylene‐3,5‐di(2 ‐pyridyl)‐4‐amino‐1,2,4‐triazole). The complex has been characterized by UV‐Vis, luminescence, 1H NMR spectroscopy and cyclic voltammetric study. The structure of ligand L and complex are confirmed by single crystal X‐ray diffraction study. The compound [Cu(L)(PPh3)I] crystallizes in the monoclinic P21/c space group with a = 19.9291(4), b = 10.0691(2), c = 21.9245(5), α = γ = 90, β = 92.481(10), and Z = 4. The complex shows a MLCT band in the 350˜545 nm region and exhibits luminescent emission at 600 nm at room temperature in dichloromethane solution. Cyclic voltammogram of [Cu(L)(PPh3)I] shows a quasi‐reversible redox couple of the copper center at 0.67 V for Cu(I)/Cu(II) and an irreversible reduction potential at −0.98 V accompanied by a stripping peak of copper at‐0.11 V for Cu(I)/Cu(0).
Hexaamide Molecule Annexed with Pyrenes for Selective Detection of Phosphate and Pyrophosphate Ions by Ratiometric Fluorescence Changes
Authors: Liao Jen‐Hai , Chen Chao‐Tsen , Fang Jim‐Min 
Published: May 2015

AbstractN,N′‐bis{3,5‐di[(1‐pyrenylmethyl)carbamoyl]benzyl}pyridine‐2,6‐dicarbamide (compound 1) provides a pseudo‐tetrahedron cleft and multiple hydrogen bondings to form a 1:1 complex with phosphate (or pyrophosphate) ion in a highly selective manner, in comparison with other anions (F−, Cl−, Br−, SCN−, AcO−, NO3−, and ClO4−). Compound 1 bears four pyrene rings as the sensitive fluorescent readout unit for phosphate and pyrophosphate ions. The binding strength can be inferred from the emission intensity ratio of the pyrene monomer (λmax = 377 nm) to the excimer (λmax ˜ 480 nm). The enhanced multiple hydrogen bondings and ratiometric sensing mechanism render an opportunity for sensing pyrophosphate ion at micromolar concentration, even in water‐containing solution. The binding model is supported by fluorescence and 1H NMR studies.
Photophysics and Homoconjugation Effect of the Acid‐base Complex between 2,4,6‐Trimethoxy‐2‐styrylquinoline and Protic Acids
Authors: Wang Li‐Ya , Wu Chieh‐Ao , Chen Yong‐Fu , Wang Shun‐Li 
Published: May 2015

AbstractThe influence of hydrogen bonding and protonation on an intra‐molecular charge transfer (ICT) compound, 2,4,6‐trimethoxy‐2‐styrylquinoline (2‐StQ‐2,4,6–30Me), was investigated in the ground state and the excited state. The acid concentration strongly influences the acid‐base reaction between 2‐StQ‐2,4,6–30Me and trifluoroacetic acid (TFA) in a non‐polar solvent. The homoconjugation effect (HE) induced by the presence of an acid was quantified by the red shift of absorption maxima. In strong protic acids, the HE was not observed. For non‐polar to moderate polar solvents, the HE value increases as solvent polarity increases. When the solvent dielectric constant was higher than that of TFA, the HE value is reduced when the solvent polarity increases.
Spin Transition of [Fe(btr)3](ClO4)2 Studied by X‐ray Absorption Spectroscopy
Authors: Lin Yen‐Chen , Hsu I‐Jui , Hsieh Hui‐Huang , Lee Jyh‐Fu , Chen Jin‐Ming , Lee Jenn‐Min , Wang Yu 
Published: May 2015

AbstractComplex [Fe(btr)3](ClO4)2 (where btr = 4,4′‐bis‐1,2,4‐triazole) exhibits an unusual two‐step spin transition at 188 K and 225 K, respectively. The corresponding three‐dimensional framework structure at each step was characterized by X‐ray diffraction. X‐ray absorption spectroscopy (XAS) at both the Fe K‐edge and the Fe L‐edge is performed to probe the exact electronic configuration at various temperatures. The two‐step behavior observed in the magnetic measurement is well reproduced by XAS. Two types of spin transitions: one abrupt and the other gradual are also observed precisely. The proper technique on monitoring the spin transition by taking advantage of synchrotron radiation is therefore established.
