ERA NanoSci - Interfacing single molecules via nanoparticle networks

我们通过使用纳米级中间体来处理纳米级分子与宏观电极的接口问题。我们的多尺度架构，基于纳米颗粒和金属纳米线的二维阵列，提供了可靠和强大的访问分子系统的电学，光学和机械性能。我们将首先探索我们的基准分子的设备平台，以获得硬-软界面的基础知识。接下来，我们将自旋跃迁系统连接起来，以在外部刺激（温度、应力、电场）下获得器件特性的巨大变化，从而解决了在不失去功能的情况下接触分子的迷人挑战。我们的研究结果将使我们能够选择未来的传感器应用在功能阵列的分子候选人。具体来说，我们将探索一种完全基于功能纳米物体（纳米颗粒和功能分子）的氢气传感装置。

We approach the problem of interfacing nanoscopic molecules with macroscopic electrodes by using nanoscale intermediates. Our multiple-scale architecture, based on two-dimensional arrays of nanoparticles and metallic nanowires, provides reliable and robust access to electrical, optical and mechanical properties of molecular systems. We will initially explore our device platforms for benchmark molecules to obtain fundamental knowledge on hard-soft interfacing. Next, we interface spin transition systems to obtain dramatic changes of device properties under external stimuli (temperature, stress, electric fields), addressing the fascinating challenge to contact a molecule without losing its functionality. Our results will enable us to select molecular candidates for future sensor applications in functional arrays. Specifically, we will explore a hydrogen gas sensing device, fully based on functional nano-objects (nanoparticles and functional molecules).
