    名称:
    Synthesis of dihydroindolizines for potential photoinduced work function alteration
    摘要:
    Seeking to immobilize photochromophores on metallic surfaces, we have synthesized four molecules which contain both a photoresponsive dihydroindolizine (DHI) core and a sulfur containing moiety, which allow for their assembly onto gold substrates. Sonogashira, Suzuki, or Ullmann couplings are employed to generate pyridines with pendant thioacetates (or disulfides). The pyridines are condensed with spiro[2-cyclopropene-1,9'[9H]fluorene]-2,3-dimethyl ester affording the targeted DHIs. (C) 2010 Elsevier Ltd. All rights reserved.

    anchor groups used in fundamental conductance studies to more elaborate anchors designed with device stability in mind. This study presents a series of oligo(phenylene-ethynylene) wires with one tetrapodal anchor and a phenyl or pyridyl head group. The new anchors are designed to bind strongly to gold surfaces without disrupting the conductance pathway of the wires. Conductive probe atomic force microscopy
    随着分子规模电子学领域的成熟以及包含分子线的器件的前景变得更加可行,有必要从基础电导研究中使用的简单锚定基团发展到考虑到器件稳定性的更精细的锚定剂。这项研究提出了一系列带有一个四脚锚和一个苯基或吡啶基头部基团的低聚(亚苯基-亚乙炔基)线。新的锚固件旨在牢固地与表面结合,而不会破坏导线的电导路径。导电探针原子力显微镜(cAFM)用于确定导线在Au-SAM-Pt和Au-SAM-石墨烯结中的自组装单层(SAMs)的电导率,由此得出每个分子的电导率。对于tolane型导线,每个分子的平均电导高达10-4。尽管与Au电极的电子耦合有限,但仍测量到37 G0(Pt)和10-3.78 G0(石墨烯),证明了这种方法的潜力。表面结合几何形状和传输性质的计算研究合理化并支持实验结果。
