    公开号:US20110224343A1
    公开(公告)日:2011-09-15
    The present invention provides a modifier for aromatic polyesters which enhances the melt fluidity of aromatic polyesters without a significant decrease in the heat resistance of the aromatic polyesters, and an aromatic polyester resin composition including the modifier for aromatic polyesters. The present invention relates to a modifier for aromatic polyesters comprising polyhydric phenol residues and residues of aromatic polycarboxylic acid, acid halide or acid anhydride thereof, and the modifier comprises a material having a structure composed of a first residue selected from the group consisting of divalent residues represented by Formula (I): —Ar—W 1 x —Ar— and by Formula (II): —Ar—, the first residues being bonded to two identical or different second residues selected from the group consisting of monovalent residues represented by Formula (III): and monovalent residues represented by Formula (IV): —O—C(O)—R 7 —.

    ligands and six complexes formed by coordination of the ligands to a Ti(IV) ion. These studies reveal that 1H T1 values can be enhanced in the individual ligands by a factor of 4 (from 10.8(3) to 43(5) s) as a function of substitution pattern, reaching the maximum value for 3,4,6-tribromocatechol. The T2 for 1H is also enhanced by a factor of 4, varying by ∼14 s across the series. When complexed, the impact
    核自旋的间隙图案化是一种新兴的设计原理,用于控制开壳络合物和固态缺陷中的电子自旋叠加寿命。本文中,我们报告了构图原理对基于配体的核自旋动力学的影响的首次测试。我们测试了配体上1 H和79/81 Br核自旋的取代构图如何调节属络合物配体壳中的质子核自旋动力学。为此,我们研究了一系列八种多邻苯二酚配体和通过配体与Ti(IV)离子配位形成的六种配合物的1 H核磁共振弛豫时间(T 1和T 2)。这些研究表明1 H T 1值可以在单个配体中提高4倍(从10.8(3)到43(5)s),作为取代模式的函数,达到3,4,6-三邻苯二酚的最大值。该Ť 2为1 H也完全是由4倍增强,通过在串联~14小号变化。当复杂化时,图案设计策略对核自旋动力学的影响被放大,并且1 H T 1和T 2值变化一个数量级。重要的是,在配体中观察到的总体趋势也与复合时的趋势相匹配。因此,这些结果证明了一种新的设计原则可以控制

    Without using any transition metal catalyst, ligand, base, toxic or hazardous reagent, additives/promoters and organic solvent, Dakin reactions have been successfully carried out by using H2O2 in neat ‘Water Extract of Banana’ (WEB) at room temperature under aerobic conditions in very short reaction times.

  • Biosynthesis of polybrominated aromatic organic compounds by marine bacteria

    Polybrominated aromatic natural products are pervasive in the marine food web. Genetic and biochemical data now establish their biosynthetic origins in marine bacteria, revealing a physiological brominase that uses an unusual decarboxylative mechanism. Polybrominated diphenyl ethers (PBDEs) and polybrominated bipyrroles are natural products that bioaccumulate in the marine food chain. PBDEs have attracted widespread attention because of their persistence in the environment and potential toxicity to humans. However, the natural origins of PBDE biosynthesis are not known. Here we report marine bacteria as producers of PBDEs and establish a genetic and molecular foundation for their production that unifies paradigms for the elaboration of bromophenols and bromopyrroles abundant in marine biota. We provide biochemical evidence of marine brominases revealing decarboxylative-halogenation enzymology previously unknown among halogenating enzymes. Biosynthetic motifs discovered in our study were used to mine sequence databases to discover unrealized marine bacterial producers of organobromine compounds.
    化芳香族天然产物在海洋食物网中无处不在。遗传和生化数据现已确定其在海洋细菌中的生物合成起源,揭示了一种使用异常脱羧机制的生理化酶。多溴联苯醚(PBDEs)和多吡啶生物累积在海洋食物链中的天然产物PBDEs因其对环境的持久性和对人类的潜在毒性而受到广泛关注。然而,PBDE生物合成的天然来源尚不清楚。在这里,我们报告了海洋细菌作为PBDEs的生产者,并建立了其生产的遗传和分子基础,统一了海洋生物群中丰富的溴吡啶的详细阐述。我们提供了海洋化酶的生化证据,揭示了脱羧-卤化酶学,这是卤化酶中以前未知的。在我们的研究中发现的生物合成模式被用来挖掘序列数据库,以发现未发现的有机化合物的海洋细菌生产者。
