  Synthesis and Properties of Bimetallic Hoveyda–Grubbs Metathesis Catalysts

  摘要：

  The catalytic activity of ruthenium Hoveyda-Grubbs complexes in olefin metathesis is a function of complex steric and electronic effects acting on initiation and propagation steps. In order to study the pi-electron factors influencing the initiation process, we attempted syntheses of bimetallic complexes with common organic ligands bearing two chelate rings. While most of the studied ligand exchange reactions of the isomeric bis-chelating benzene derivatives gave mixtures of unstable complexes, a homodinuclear derivative of 1,4-dimethoxy-2,5-divinylbenzene was sparingly soluble and precipitated from the reaction mixture in a pure form. The complex was studied with spectroscopic and X-ray methods, which confirmed the symmetrical bimetallic structure. However, in model metathesis reactions the catalyst displayed activity very comparable to the related monometallic complexes. This suggests that in the bimetallic system two consecutive initiation processes of the metathesis catalyst (first, bimetallic complex + olefin -> monometallic complex + propagating species; second, monometallic complex + olefin -> styrene + propagating species) proceed at similar rates and, thus, no cooperativity between the two steps is displayed. Properties of the family of bimetallic complexes were probed with NMR studies, and pi-electronic effects operating in the systems were discussed.

  阳离子共轭聚合物用于区分微生物病原体

  摘要：

  合成了一种新的阳离子聚亚苯基亚乙烯基衍生物（PPV-NMe 3 +），它对具有不同成分的微生物细胞壁具有不同的结合能力。通过改变缓冲溶液的离子强度，单个PPV-NMe 3 +分子可以快速，简单地区分真菌，革兰氏阳性细菌和革兰氏阴性细菌。因此，阳离子共轭聚合物作为检测和鉴别病原体的诊断材料显示出很高的潜力。

  The present invention relates to solar cells and discloses a difluoro benzotriazolyl organic semiconductor material and preparation method and use thereof. The organic semiconductor material is represented by formula (I), wherein both R1 and R2 are C1 to C20 alkyl, and n is an integer from 10 to 50. In the difluoro benzotriazolyl organic semiconductor material, since the 1, 2, 3-benzotriazole organic semiconductor material contains two fluorine atoms, the HOMO energy level is reduced by 0.11eV, while the fluorine-substituted 1, 2, 3-benzotriazole has two imido groups with electron-withdrawing ability; the fluorine-substituted 1, 2, 3-benzotriazole is a heterocyclic compound with strong electron-withdrawing ability, and an alkyl chain can be easily introduced to the N-position of the N-H bond of the benzotriazole. The functional group of the alkyl chain can improve the solar energy conversion efficiency, thus solving the low efficiency problem of solar cells made of the organic semiconductor material.

  本发明涉及太阳能电池，公开了一种二氟苯并三唑基有机半导体材料及其制备方法和用途。该有机半导体材料由式（I）表示、 其中 R1 和 R2 均为 C1 至 C20 烷基，n 为 10 至 50 的整数。在二氟苯并三唑有机半导体材料中，由于 1，2，3-苯并三唑有机半导体材料含有两个氟原子，因此 HOMO 能级降低了 0.11eV，而氟取代的 1，2，3-苯并三唑具有两个具有吸电子能力的亚氨基；氟取代的 1，2，3-苯并三唑是一种具有较强吸电子能力的杂环化合物，在苯并三唑的 N-H 键的 N 位上很容易引入烷基链。烷基链的官能团可以提高太阳能转换效率，从而解决有机半导体材料制成的太阳能电池效率低的问题。
