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).

我们利用纳米中间体研究了纳米分子与宏观电极的界面连接问题。我们的多尺度架构，基于纳米粒子和金属纳米线的二维阵列，为分子系统的电学、光学和机械特性提供了可靠和强大的途径。我们将首先探索我们的基准分子的设备平台，以获得硬-软接口的基本知识。接下来，我们将界面自旋跃迁系统，以在外部刺激（温度，应力，电场）下获得器件性能的巨大变化，解决接触分子而不失去其功能的迷人挑战。我们的研究结果将使我们能够为未来传感器在功能阵列中的应用选择候选分子。具体来说，我们将探索一种完全基于功能纳米物体（纳米粒子和功能分子）的氢气传感装置。
