Bioorganometallic ChemistryFerrocene-based derivative bearing phenol group recognitive sites: efficient H2PO4- receptor (p 821-825) X. F. Shang, H. Lin, X. F. Xu, P. Jiang, H.. Lin Published Online: Jul 24 2007 6:23AM
DOI: 10.1002/aoc.1254
| | | The anion-binding properties of ferrocene-based receptors bearing phenol group are evaluated for F-, Cl-, Br-, I-, AcO- and by UV-vis, 1H NMR titration and cyclic voltammetry experiments. Results indicate that the anion binding abilities can be effectively tuned by introducing nitro group in the ortho position of phenyl ring of the receptors, and the most obvious effect is for . | | |

| | | Synthesized continuous NaA membranes were prepared using a 0.5 µm NaA crystal seed via vacuum seeding. The optimum conditions were 363 synthesis temperature for 15-20 min via microwave heating. The flux and separation factor obtained were 1.56g/m2 h and 1760.52, respectively, for the substrate without an intermediate layer. Interestingly, the substrate with an intermediate layer showed better flux and separation factor at 1.69g/m2 h and 6532.72, respectively. | | |

A novel route to perovskite lead zirconate from lead glycolate and sodium tris(glycozirconate) via the sol-gel process (p 849-857) N. Tangboriboon, A. Jamieson, A. Sirivat, S. Wongkasemjit Published Online: Jul 24 2007 6:26AM
DOI: 10.1002/aoc.1303
| | | A perovskite lead zirconate was synthesized, using lead glycolate and sodium tris (glycozirconate) as the starting precursors, by the sol-gel process. The structure obtained was the orthorhombic form when calcined at low temperature at 300 °C for 1 h and transformed to the monoclinic and cubic forms of the perovskite phase at higher temperatures above the Curie temperature as verified by X-ray data. The lead zirconate synthesized and calcined at 300 °C for 1 h has the highest dielectric constant, the highest electrical conductivity, and the dielectric loss tangent of 2267, 3.058 × 10-4 ( .m)-1, and 2.484 at 1000 Hz, respectively. | | |

Surface modification of quarry stone by hexamethyldisiloxane plasma treatment (p 858-861) Jose A. López-Barrera, Alejandro Avila-Ortega, Juan Morales, Jorge Cervantes, Roberto Olayo Published Online: Jul 31 2007 6:41AM
DOI: 10.1002/aoc.1304
| | | The surface of quarry stone was modified by continuous plasma polymerization of hexamethyldisiloxane. The hydrophilic surface of the quarry stone was made hydrophobic and impermeable to water. Three different reaction times were analyzed. Contact angle and FT-IR analyses show that the hydrophobic character of the surface is due to methyl groups on the surface. The change in the contact angle with temperature and the wetting temperature (Tw) were measured. | | |

Synthesis and physicochemical studies of ferrocene-containing materials (p 862-869) Naseer Iqbal, Muhammad Saif ullahhan, M. Adnan Saeed, Zareen Akhter Published Online: Aug 7 2007 4:46AM
DOI: 10.1002/aoc.1266
| | | Three aromatic diamines, 2,6-di-(4- aminophenyloxy) toluene (A), 2,2 -di-[4-(4-aminophenyloxy) phenyl] propane (B) and 4,4 -di (4-aminophenyloxy) biphenyl (C), were obtained by reacting 2,6-dihydroxytoluene, bisphenol-A and 4,4 -dihydroxybiphenyl with p-nitrochlorobenzene. The synthesized diamines were then polymerized with 1,1 -ferrocenedicarboxylic acid chloride with low-temperature polycondensation to produce organometallic aromatic polyamides (aramids). The synthesized monomers and polymers were characterized by their solubilities, elemental analysis, FTIR spectroscopy and 1H-NMR spectroscopy. The inherent viscosities, differential scanning calorimetry and thermogravimetry were also used for polymer characterization. | | |

-olefin homopolymerization and ethylene/1-hexene copolymerization catalysed by novel ansa-group IV complexes/MAO system (p 870-879) Xiaoxia Yang, Yong Zhang, Jiling Huang Published Online: Aug 7 2007 4:44AM
DOI: 10.1002/aoc.1298
| | | The new ansa-complexes were used on ethylene homopolymerization, -olefin homopolymerization, ethylene/ -olefin copolymerization. When tBu was introduced into the para position on phenyl groups in (Ph2C(Cp)(Ind) ZrCl2), the activity and the incorporation of 1-hexene on copolymerization were both increased. | | |

| | | A series of organotin compounds have been characterised spectroscopically and by X-ray crystallography. The tin atom is penta-coordinated in each case and the majority of structures associate via eight-membered {N-C-N-H}2 synthons. The efficacy of these compounds against a range of bacteria, fungi, plant pathogens and human cancer cell lines is also described. | | |
