      Synthesis of Coumarin-Pillar[5]arene as a Selective Fluorescent Probe for Methyl-Parathion

      Fan Zhang, Xianliang Cao, Demei Tian and Haibing Li

      Article first published online: 14 JAN 2015 | DOI: 10.1002/cjoc.201400675

      A novel coumarin-pillar[5]arene derivative (P5C10) was prepared. Fluorescence spectroscopy indicates that P5C10 shows good selectivity towards methyl-parathion. A combination of NMR spectra, MALDI-TOF spectra and computational calculations reveals the formation of a host-guest complex driven by π-π stacking interactions.

      The synergistic flame retardancy of Clay20 in PP/MB matrix significantly improved the fire safety, which was attributed to the improvement in forming a reinforced protective barrier on the surface of samples. Meanwhile, Young's modulus and impact strength of the composites were increased because the rigid needlelike Clay20 in PP composites directly enhanced the stiffness of flame retardant composites.

      Article first published online: 14 JAN 2015 | DOI: 10.1002/cjoc.201400633

      A method for sensitive determination of five priority haloacetic acids in drinking water has been developed for the first time based on electromembrane extraction (EME) prior to CZE with capacitively coupled contactless conductivity detection (CZE- C4D). Under the optimum conditions, five haloacetic acids (monochloroacetic acid, dichloroacetic acid, trichloroacetic acid, monobromoacetic acid, and dibromoacetic acid) could be well separated from other components coexisting in water samples within 23 min, exhibiting a linear calibration over two orders of magnitude (r>0.994); the LODs were in the range of 0.17–0.61 ng/mL and the enrichment factor could be up to 671-fold. This approach offers an attractive alternative for drinking water analysis.

      Different nanostructures composed of 1-pyrenecarboxaldehyde (Py-CHO) and tetraphenylethylenecarboxaldehyde (TPE-CHO) were obtained by decomposition-assembly of poly(allylamine hydrochloride) (PAH)-g-Py-g-TPE at low pH, which was synthesized by grafting Py-CHO and TPE-CHO to PAH via a Schiff base reaction. The PAH-g-Py-g-TPE micelles were transformed into nanomaterials including nanoparticles (NPs), nanorods (NRs), nanotubes (NTs) and nanoribbons (NBs) at low pH, which emitted fluorescence with colors different from their counterpart NTs and NPs formed from the parent Py-CHO and TPE-CHO molecules.

      Mengxi Wu, Haoyang Wang, Guoqing Dong, Brian D. Musselman, Charles C. Liu and Yinlong Guo

      Article first published online: 9 DEC 2014 | DOI: 10.1002/cjoc.201400564

      Thumbnail image of graphical abstract

      A method for rapid identification and quantification of 15 phthalate plasticizers in beverages was developed. By a combined solid-phase micro-extraction (SPME) and direct analysis in real time mass spectrometry (DART-MS) approach, phthalates at sub-ng·mL−1 levels can be qualitatively and quantitatively analyzed in a short time. The use of ultrahigh-resolving power and the accurate mass measurement capacity naturally provided by Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS) minimizes the matrix interferences and thus enables the evaluation of phthalates in a complex matrix without extensive sample handlings or preparations. This rapid and easy-to-use SPME-DART-FT-ICR-MS method provided a relatively high-throughput and powerful analytical approach for quick testing and screening phthalates in beverages and water samples to ensure food safety.
