Abstract

Molecular complexes based on donor-acceptor interactions that involve π-systems with antiaromatic character are rarely studied. Herein, we report the synthesis of biphenylene derivatives as potential electron donor components in π-complexes. Molecules with two connected biphenylene units are suitable to probe the formation of differently folded complexes in solution, while biphenylene derivatives with a pendant triethoxysilane group can be used to functionalize solid surfaces and probe interfacial donor-acceptor complex formation. Our results show clear indication of complex formation in solution; however, no observable interaction was found on the surface using UV-vis spectroscopy.

构建二苯基二聚体和表面结合层以探索供体-受体相互作用

基于供体-受体相互作用的分子配合物涉及具有反芳香性质的π-体系，研究较少。本文报道了在π配合物中作为潜在电子给体组分的联苯衍生物的合成。具有两个连接的联苯单元的分子适合探测溶液中不同折叠的配合物的形成，而具有悬垂的三乙氧基硅烷基团的联苯衍生物可用于功能化固体表面和探测界面供体-受体配合物的形成。结果表明，溶液中有明显的复杂结构；然而，用紫外-可见光谱法在表面未发现可观察到的相互作用。

期刊介绍： Structural Chemistry is an international forum for the publication of peer-reviewed original research papers that cover the condensed and gaseous states of matter and involve numerous techniques for the determination of structure and energetics, their results, and the conclusions derived from these studies. The journal overcomes the unnatural separation in the current literature among the areas of structure determination, energetics, and applications, as well as builds a bridge to other chemical disciplines. Ist comprehensive coverage encompasses broad discussion of results, observation of relationships among various properties, and the description and application of structure and energy information in all domains of chemistry. We welcome the broadest range of accounts of research in structural chemistry involving the discussion of methodologies and structures,experimental, theoretical, and computational, and their combinations. We encourage discussions of structural information collected for their chemicaland biological significance.
