Abstract

The coverage dependence of self-assembled structures for 1,3-diazaphenalene (DAP) has been investigated using low-temperature scanning tunneling microscopy and molecular orbitals calculations. We find that one dimensional zigzag chains of DAP are formed through sequential NH

\dots

N hydrogen bonding between molecules with a head-to-head configuration. These chains tend to align perpendicular to the bright lines of the reconstruction patterns on the Au(111) surface. Repulsive interactions between the chains are attributed to the formation of dipoles at the molecule-surface interface, which arise from electron transfer from DAP to the Au surface.

表面重构对金（111）上二叠苯烯自组装的影响

利用低温扫描隧道显微镜和分子轨道计算研究了1,3-二氮杂苯烯（DAP）自组装结构的覆盖依赖性。我们发现DAP的一维之字形链是通过具有头对头结构的分子之间的顺序NH⋯N氢键形成的。这些链倾向于垂直于Au（111）表面重建图案的亮线排列。链之间的排斥性相互作用归因于分子表面界面上偶极子的形成，这是由电子从DAP转移到Au表面引起的。

期刊介绍： Surface Science is devoted to elucidating the fundamental aspects of chemistry and physics occurring at a wide range of surfaces and interfaces and to disseminating this knowledge fast. The journal welcomes a broad spectrum of topics, including but not limited to: • model systems (e.g. in Ultra High Vacuum) under well-controlled reactive conditions • nanoscale science and engineering, including manipulation of matter at the atomic/molecular scale and assembly phenomena • reactivity of surfaces as related to various applied areas including heterogeneous catalysis, chemistry at electrified interfaces, and semiconductors functionalization • phenomena at interfaces relevant to energy storage and conversion, and fuels production and utilization • surface reactivity for environmental protection and pollution remediation • interactions at surfaces of soft matter, including polymers and biomaterials. Both experimental and theoretical work, including modeling, is within the scope of the journal. Work published in Surface Science reaches a wide readership, from chemistry and physics to biology and materials science and engineering, providing an excellent forum for cross-fertilization of ideas and broad dissemination of scientific discoveries.
