  空间相互作用中的激发态奇偶效应

  摘要：

  奇偶效应是自然界中一种奇妙的现象，它已被应用于有机自组装单分子层和液晶等多个领域。目前，每个奇偶效应的起源仍然难以捉摸，所有报道的奇偶效应都与基态特性有关。在这里，我们发现非共轭四苯基烷烃（TPA）的穿越空间相互作用（TSI）中存在激发态奇偶效应。具有偶数个烷基碳原子的TPA（C2-TPA、C4-TPA和C6-TPA）表现出强TSI、长波长发射和高QY。然而，奇数（C1-TPA、C3-TPA、C5-TPA 和 C7-TPA）几乎不存在，QY 可以忽略不计。系统的实验和理论结果表明，激发态奇偶效应是由烷基几何形状、分子运动性和分子间堆积三个因素综合决定的。此外，这些柔性发光TPA在荧光信息加密方面具有巨大的优势。这项工作将奇偶效应扩展到光物理学，证明了其在自然界中的重要性和普遍性。

  Oxyguanidines: application to non-peptidic phenyl-based thrombin inhibitors

  摘要：

  Although thrombin has been extensively researched with many examples of potent and selective inhibitors, the key characteristics of oral bioavailability and long half-life have been elusive. We report here a novel series non-peptidic phenyl-based, highly potent, highly selective and orally bioavailable thrombin inhibitors using oxyguanidines as guanidine-mimetics.

• The<i>in situ</i>-Generated Nickel(0)-catalyzed Homo-coupling of Alkenyl Halides with Zinc Powder. A Specific Outcome in Stereochemistry

  The catalytic activity of nickel(0) generated in situ from nickel(II) salt was examined in a dehalogenative coupling of alkenyl halides with zinc powder. The reaction of alkenyl bromides took place provided that potassium iodide was present to assist the reduction of nickel(II) with zinc powder, and also to convert the alkenyl bromides to the corresponding alkenyl iodides.

• Ethics and Foreign Policy: The Antinomies of New Labour's ‘Third Way’ in Sub-Saharan Africa
  作者：Rita Abrahamsen、Paul Williams

  DOI：10.1111/1467-9248.00312

  日期：2001.6

  This article explores how New Labour has attempted to implement its ideas about a ‘third way’ foreign policy in sub-Saharan Africa. Through an examination of British foreign policy practices, we explore whether New Labour has succeeded in finding a ‘third way’ between traditional views of socialism and capitalism in Africa. In particular, the article focuses on New Labour's attempts to build peace, prosperity and democracy on the African continent. We conclude that although New Labour's claims to add an ‘ethical dimension’ to foreign policy have succeeded in giving Britain a higher profile in the international arena, the implementation of such a policy is intrinsically difficult. These difficulties in turn arise from the antinomies embodied in New Labour's policy, or more specifically from the tension between the liberal internationalism of the third way and traditional concerns for the national interest, as well as the contradictions inherent in a commitment to both political and economic liberalism.

  这篇文章探讨了新工党如何试图在撒哈拉以南非洲实施其关于“第三条道路”外交政策的想法。通过对英国外交政策实践的审查，我们探讨新工党是否成功地在非洲传统社会主义和资本主义观念之间找到了一种“第三条道路”。特别是，文章关注新工党在非洲大陆上建立和平、繁荣和民主的努力。我们得出结论，尽管新工党声称在外交政策中增加了“道德维度”成功地使英国在国际舞台上更加引人注目，但这种政策的实施本质上是困难的。这些困难反过来源于新工党政策所体现的矛盾，更具体地说，源于第三条道路的自由国际主义与对国家利益的传统关注之间的紧张关�
