  Fabrication of Steady Junctions Consisting of α,ω-Bis(thioacetate) Oligo(p-phenylene vinylene)s in Nanogap Electrodes

  摘要：

  For obtaining molecular devices using metal-molecule-metal junctions, it is necessary to fabricate a steady conductive bridge-structure; that is stable chemical bonds need to be established from a single conductive molecule to two facing electrodes. In the present paper, we show that the steadiness of a conductive bridge-structure depends on the molecular structure of the bridge molecule for nanogap junctions using three types of modified oligo(phenylene vinylene)s (OPVs): alpha,omega-bis(thioacetate) oligo(phenylene vinylene) (OPV1), alpha,omega-bis(methylthioacetate) oligo(phenylene vinylene) (OPV2), and OPV2 consisting of ethoxy side chains (OPV3). We examined the change in resistance between the molecule-bridged junction and a bare junction in each of the experimental Au-OPV-Au junctions to confirm whether molecules formed steady bridges. Herein, the outcomes of whether molecules formed steady bridges were defined in terms of three types of result; successful, possible and failure. We define the ratio of the number of successful junctions to the total number of experimental junctions as successful rate. A 60% successful rate for OPV3 was higher than for the other two molecules whose successful rates were estimated to be similar to 10%. We propose that conjugated molecules consisting of methylthioacetate termini and short alkoxy side chains are well suited for fabricating a steady conductive bridge-structure between two facing electrodes.

  Two new segmented conjugated polymers bearing distyrylbenzene chromophoric units and their model compounds were synthesized. The tendency of the model compounds to form H- and J-type aggregates in the amorphous matrix was greatly diminished by the twisted polymeric architecture. Fluorescence anisotropy measurements indicated good exciton mobilities in condensed phase. Fluorescence quenching by nitroaromatic

  合成了两个带有二苯乙烯基苯发色单元的新型分段共轭聚合物及其模型化合物。扭曲的聚合物结构大大降低了模型化合物在无定形基质中形成H型和J型聚集体的趋势。荧光各向异性测量表明在凝聚相中具有良好的激子迁移率。硝基芳族水溶液的荧光猝灭作用快速，完全，选择性和可逆，表明分析物迅速扩散到薄膜中。对硝基酚的猝灭反应优于对硝基甲苯的猝灭反应。二乙氧基取代取代给电子体的能力增加对无定形形态是有害的，并且不增加对NAC的敏感性。当使用MeOH代替水时，聚合物的淬灭效​​率没有改变。溶解度参数距离，[R一。表示传感材料与分析物的亲和力较低时，其显示较高的响应。该观察结果可有助于荧光传感器的设计。
