A sandwich-type (phthalocyaninato)(porphyrinato) europium double-decker complex Eu(TPyP){Pc-(OC8H17)8} [TPyP = meso-tetra(4-pyridyl)porphyrin; Pc-(OC8H17)8 = 2,3,9,10,16,17,23,24-octakis(octyloxy)phthalocyanine] (2) was designed and prepared. For comparative studies, Eu(TPyP)(Pc) (1) was also prepared. Highly ordered nanotubes of complexes 1 and 2 were successfully fabricated by using an anodized alumina oxide (AAO) template method. The nanotubes were comparatively investigated by electronic absorption spectra, scanning electron microscopy (SEM), low-angle X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and energy dispersive spectroscopy (EDS) techniques. Both nanotubes of complexes 1 and 2 showed good conductivities and presented an efficient gas sensing platform for the ultrasensitive detection of NO2 at room temperature. In particular, the detection limit and response/recovery times for the proposed sensors based on complex 2 were lower and faster than those of complex 1, indicating the significant effect of a molecular packing mode on tuning the gas sensing performance of organic semiconductors. © 2017 The Royal Society of Chemistry.

Phosphorus (P) efficiency (PE), which comprises phosphorus uptake (PupE) and utilization efficiency (PutE), is considered as one of the most important factors for crop yield. In the present study, 11 seedling traits and 13 maturity traits related to wheat PE and morphology were investigated using a set of recombinant inbred lines (RILs) derived from the cross of “TN 18 × LM 6,” under hydroponic culture trials and field trials at low P (LP) and normal P (NP) levels in two different years, respectively. The LP input reduced of biomass, yield and PupE traits, but increased PutE traits. A total of 163 QTLs for seedling and maturity traits under different P levels and their AV, and 15 QTLs for relative traits were detected on 21 chromosomes. Of these, 49 and 63 QTLs for were detected specially in LP and NP treatments, respectively. We found 11 relatively high-frequency QTLs (RHF-QTLs) and four important QTL clusters, which may be the potential targets for marker-assisted selection (MAS) in wheat breeding programs for PE. Favorable relationships for breeding programs were found in the four important QTL clusters, which allow the possibility of improving the morphological traits and PutE simultaneously. A total of 29 markers which associated with 51 QTLs were found highly homologous with EST sequences, which suggested that they were potential functional loci. We suggested that the four biomass traits (SDW, RDW, TDW, and RSDW), five yield traits (SN, PH, TGW, GWP, and StWP) and two relative traits (Rstwp and Rgwp) can be considered as the primary indexes for the evaluation of PE for they are easy to identify on a large-scale. © 2017 Yuan, Gao, Zhang, Zheng, Zhou, Guo, Zhao, Kong and Li.

The relationships between diet and metabolites as well as element profiles in healthy centenarians are important but remain inconclusive. Therefore, to test the interesting hypothesis that there would be distinctive features of metabolites and element profiles in healthy centenarians, and that these would be associated with nutrient intake; the short chain fatty acids (SCFAs), total bile acids and ammonia in feces, phenol, p-cresol, uric acid, urea, creatinine and ammonia in urine, and element profiles in fingernails were determined in 90 healthy elderly people, including centenarians from Bama county (China)—a famous longevous region—and elderly people aged 80–99 from the longevous region and a non-longevous region. The partial least squares-discriminant analysis was used for pattern recognition. As a result, the centenarians showed a distinct metabolic pattern. Seven characteristic components closely related to the centenarians were identified, including acetic acid, total SCFA, Mn, Co, propionic acid, butyric acid and valeric acid. Their concentrations were significantly higher in the centenarians group (p < 0.05). Additionally, the dietary fiber intake was positively associated with butyric acid contents in feces (r = 0.896, p < 0.01), and negatively associated with phenol in urine (r = −0.326, p < 0.01). The results suggest that the specific metabolic pattern of centenarians may have an important and positive influence on the formation of the longevity phenomenon. Elevated dietary fiber intake should be a path toward health and longevity. © 2016 by the authors; licensee MDPI, Basel, Switzerland.

Two novel amphiphilic porphyrin derivatives, 5-(benzo-(4-(2-(2-hydroxy)ethoxy)ethoxy))-10,15,20-triphenylporphyrinato zinc complex [ZnT(OC2H4OC2H4OH)PP] (1) and 5-(benzo-(4-(2-(4,10-N,N-15-crown-5)ethoxy)))-10,15,20-triphenylporphyrinato zinc complex [ZnT(OC2H4NN15C5)PP] (2), were designed, synthesized, and characterized by a range of spectroscopic methods. Their electrochemistry was studied by differential pulse voltammetry (DPV). Highly ordered films of 1 and 2 were fabricated by a solution-based quasi-Langmuir-Shäfer (QLS) technique, and were characterized by electronic absorption spectroscopy, IR spectroscopy, X-ray diffraction, atomic force microscopy (AFM) and current-voltage (I-V) measurements. Experimental results revealed that J-type aggregates are formed in the QLS film of 1 and 2. The crystallinity and general molecular order in the film of 1 were improved more effectively than in 2 due to its stronger intermolecular interactions. Furthermore, the conductivity of the QLS film of 1 was approximately 1 order of magnitude larger than that of 2. This indicates a significant effect of peripheral groups on the conducting behavior of porphyrins. In addition, the gas sensing behavior of the QLS films of 1 and 2 toward the electron acceptor gas, NO2, was investigated at concentrations 200 and 800 ppm, respectively. The sensitivity, stability, and reproducibility follow the order 1 > 2, revealing the effect of intermolecular interaction, film structure/morphology, and low-lying LUMO energy level on sensing performance. Unexpectedly, a decreased current response towards NO2 for the QLS films of both 1 and 2 was obtained for the first time, which unambiguously demonstrated the n-type semiconducting nature of 1 and 2. The present result represents not only the first example of n-type metalloporphyrin-based thin solid films obtained by a solution-based method, but more importantly provides an efficient way to enhance the performance of n-channel organic semiconductors through the combination of molecular design and the film fabrication technique. © The Royal Society of Chemistry and the Centre National de la Recherche Scientifique 2016.

A novel diimide-linked, iron(III) containing porous organic polymer (FePPOP) was designed and synthesized by the raise-by-one-story method using iron(III)tetraaminophthalocyanine and 3,4,9,10-perylene tetracarboxylic dianhydride. The yielded polymer has been fully characterized by IR, X-ray diffraction, scanning electron microscopy, thermal gravimetric analysis and nitrogen sorption isotherm measurements. FePPOP has unique morphological properties e.g. amorphous, insoluble, multilayered microporous structure. It also served as an efficient heterogeneous catalyst in the oxidation reaction of benzyl alcohol to benzaldehyde under mild reaction condition with a large turnover number as high as 960. The present work showcased a group of structure–function relationship among molecular structure, porous organic polymer structure, and catalyst functional properties. It would attract great research interest in the catalysis applications of a new class of porous organic polymers in organic reactions. © 2015 Springer Science+Business Media New York

Pre-anthesis-synthesized proteins stored in the vegetative organs of cereal crops are re-mobilized and transferred to the grains. In this study, winter wheat (Triticum aestivum L.) was grown at levels of 225 kg N ha-1 (normal) and 330 kg N ha-1 (high) to investigate the effects of excessive N rates on the N re-mobilization from vegetative organs to the developing grains and on the grain protein yield. At a high N dose, the activities of the major flag leaf proteases were greatly decreased ~8-24 days after anthesis. From the beginning of the grain filling to the maturity, the post-anthesis flag leaf protein contents reduced by 80.50% and 70.40% at normal and high N rates, respectively (P < 0.05). The wheat flag leaves grown under high N conditions had a higher residual N at maturity than those grown under normal N conditions. Thus, up to maturity, the flag leaf N translocation efficiency was 67.4% in wheat exposed to a high N rate, significantly lower than the 73.8% of the plants exposed to a normal N rate (P < 0.05). Consequently, the grain protein content was not significantly increased with high N fertilization. In conclusion, the application of excessive N inhibits the proteolysis and decreases the export of flag leaf-stored protein to the developing grains and therefore, may not improve the protein yield in wheat. © 2012 Friends Science Publishers.

An amphiphilic mixed (phthalocyaninato) (porphyrinato) europium(III) triple-decker complex [Pc(OPh)8]Eu[Pc(OPh)8]Eu[TP(CCCOOH)PP] (1) with potential ambipolar semiconducting HOMO and LUMO energy levels has been designed, synthesized, and characterized. The OFET devices fabricated by quasi-Langmuir-Shfer (QLS) technique at the air/water interface with nanoparticle morphology display hole mobility of 7.0 10(-7) cm(2) V(-1) s(-1) and electron mobility of 7.5 10(-7) cm(2) V(-1) s(-1), which reflects its ambipolar semiconducting nature. However, the performance of the devices fabricated via a phase-transfer method from n-hexane with one-dimensional nanoribbon morphology was significantly improved by 3-6 orders of magnitude in terms of hole and electron mobilities, 0.11 and 4 10(-4) cm(2) V(-1) s(-1), due to the enhanced - interaction in the direction perpendicular to the tetrapyrrole rings associated with the formation of a dimeric supramolecular structure building block depending on the intermolecular hydrogen bonding between the neighboring triple-decker molecules in the one-dimensional nanoribbons.
