项目摘要

The bottom-up assembly of functional nanoscale architecture from molecular components at the surface has attracted much interest in the advancement of nanotechnology. Particularly, the chemistry of surface modification by self-assembled monolayers (SAM) and layer-by-layer (LbL) growth of multilayers is highly promising to construct two-dimensional (2D) and three-dimensional (3D) chemical systems on surfaces. To attain this aim, we have undertaken two synthetic approaches based on surface coordination chemistry; i.e., (1) fabrication and functions of multilayers based on redox-active metal complexes on surface, introducing, and (2) DNA nanowiring between two gold terminals on Au/Si02 patterned surface.Novel molecular units with tetrapod or hexapod phosphonate anchoring groups(XP) have been synthesized in order to keep the molecular orientation on the surface. Mono- and dinuclear Ru complexes, [Ru(XP) (btpb)] and 〔[Ru2(XP)2] (btpb)〕, have been immobilized on an ITO electrode. The vertical molecular orientation was supported by AFM measurements. The direction of photocurrent was altered by the direction of applied potential pulse; i.e., the positive potential pulse (0 V -+1 V - 0 V) revealed a cathodic transient photocurrent, however the negative potential pulse (0 V - -1 V - 0 V) gave an anodic current. These responses fulfill a fundamental requirement for molecular memory functionality. Nanowiring of λ-DNA molecules on the micrometer-sized Au/Si02 patterned silicon substrate was also studied.
自下而上的组装功能纳米结构的分子组件在表面上吸引了很多兴趣,在纳米技术的进步。特别地,通过自组装单分子层(SAM)和多层膜的逐层(LbL)生长的表面改性化学非常有希望在表面上构建二维(2D)和三维(3D)化学系统。为了实现这一目标,我们采用了两种基于表面配位化学的合成方法;即,(1)(2)在Au/SiO2图案化表面的两个金端之间引入DNA,合成了具有四足或六足膦酸酯锚定基团(XP)的新型分子单元,以保持分子在表面上的取向。单核和双核钌配合物[Ru(XP)(btpb)]和[[Ru_2(XP)_2](btpb)]被固定在ITO电极上。垂直分子取向的AFM测量支持。光电流的方向被施加的电势脉冲的方向改变;即,正电位脉冲(0 V -+1V-0V)显示阴极瞬态光电流,而负电位脉冲(0 V --1V-0V)显示阳极电流。这些反应满足了分子记忆功能的基本要求。还研究了λ-DNA分子在微米尺寸的Au/SiO2图案化硅衬底上的纳米线。
