  摘要：

  In the structure of the title compound, C24H24O2, one of the two types of six-membered rings is planar and the other is in a skew-boat conformation. The ethylene C=C bond distance is 1.345 (3) Angstrom. The substituents at the ethylene are in an E configuration. The crystal structure consists of discrete molecules lying about inversion centres, held together by van der Waals contacts.

  摘要：

  在本文中，报道了新型有机二元体3-(1-甲氧基-3,4-二氢-萘-2-基-)-1-对氯苯基丙烯酮的合成和表征方法。在本文中，我们的主要目标是通过将有机二元体与不同的贵金属、半导体纳米粒子和贵金属-半导体核/壳纳米复合材料相结合来制造新型杂化纳米复合材料。在这个有机二元体中，供体部分是 1-甲氧基-3, 4-二氢-萘-2-甲醛，受体是对氯苯乙酮。我们对二元体及其混合纳米复合材料系统进行了稳态和时间分辨光谱测量。还使用Gaussian 03软件进行了一些量子化学计算，从理论角度支持了实验结果。理论预测和核磁共振研究表明，在基态下，仅存在二元体的延伸（E型或反式）构象，而在光激发下，这些延伸的构象异构体转化为折叠形式（Z型或顺式）的二元体，显示其光切换特性。时间分辨荧光光谱（TCSPC 方法的荧光寿命）测量表明，在氯仿介质中，本研究中研究的所有有机-无机杂化纳米复合材料，即使在激发单线态下，也相对于折叠构象体具有大量的延伸构象体。这表明相对于与二元组内的电荷分离相关的速率过程，能量破坏性电荷复合速率可能较慢。研究发现，在 CHCl3 介质中，对于单独的二元体和其他混合纳米复合材料系统，计算出的电荷分离率为 ∼108 s−1。从相应混合系统的瞬态吸收测量中观察到，该速率比浪费能量的电荷复合速率~102-101 s−1 更快。这表明构象几何形状对电荷分离和复合速率过程有很大影响。观察到的离子对寿命较长，暗示了本文研究的所有系统都适合构建高效的光能转换装置，特别是使用 Ag-Dyad 纳米复合材料。

• Synthesis and biological evaluation of guanylhydrazone coactivator binding inhibitors for the estrogen receptor

  Most patients with hormone-responsive breast cancer eventually develop resistance to traditional antiestrogens such as tamoxifen, and this has become a major obstacle in their treatment. We prepared and characterized the activity of a series of 16 guanylhydrazone small molecules that are designed to block estrogen receptor (ER) activity through a non-traditional mechanism, by directly interfering with coactivator binding to agonist-liganded ER. The inhibitory activity of these compounds was determined in cell-based transcription assays using ER-responsive reporter gene and mammalian two-hybrid assays. Several of the compounds gave IC50 values in the low micromolar range. Two secondary assays were used to confirm that these compounds were acting through the proposed non-traditional mode of estrogen inhibitory action and not as conventional antagonists at the ligand binding site.

• A frank synthesis of alkyl–aryl ethers from 2-halobenzaldehydes and aromatic olefins without transition metal co-catalyst and ligand

  An efficient synthesis of alkyl ethers has been developed for o-deactivated aryl halides and 1-halotetralenes. The method shows good regioselectivity towards ortho substituted halides. Alkali metal carbonates (Li2CO3/Na2CO3/K2CO3/Cs2CO3) have been used without a transition metal co-catalyst and ligand. The method is simple, straight-forward and proceeds to afford products in good isolated yields. The method holds potential for future applications in organic synthesis. (C) 2015 Elsevier Ltd.
