摘要:

将功能分子组装成传感器器件是分子电子学中的一个新兴领域,其目的是利用不同分子对其环境的敏感性并将其转化为电信号。在新兴的传感器,微机电系统是有前途的,他们的极端敏感性的机械事件。然而,为了给这些器件带来新的功能,需要用多功能分子对其表面进行功能化。在这里,我们提出了一个集成的聚合物微机电谐振器与可切换的磁性分子功能化的原始混合装置。通过在分子水平上切换它们的磁状态而引起的它们的机械性质和几何形状的改变了器件的动力学行为,从而导致共振频率的改变。我们证明,该设备可以操作,以感测光或热激发。此外,由于可切换分子的集体相互作用,该设备表现为非易失性存储器。我们的研究结果开辟了新的灵活的光和热活性混合器件的分子为基础的数据存储和传感器的广阔前景。

英文摘要:

Incorporating functional molecules into sensor devices is an emerging field in molecular electronics that aims at exploiting the sensitivity of different molecules to their environment and turning it into an electrical signal. Among the emergent sensors, microelectromechanical systems are promising for their extreme sensitivity to mechanical events. However, in order to bring new functions to these devices, the functionalization of their surface with multifunctional molecules is required. Herein, we present original hybrid devices made of an integrated polymer microelectromechanical resonator functionalized with switchable magnetic molecules. The change of their mechanical properties and geometry induced by the switching of their magnetic state at a molecular level alters the device dynamical behavior, resulting in a change of the resonance frequency. We demonstrate that the device can be operated to sense light or thermal excitation. Moreover, thanks to the collective interaction of the switchable molecules, the device behaves as a nonvolatile memory. Our results open up broad prospects of new flexible photo and thermoactive hybrid devices for molecule based data storage and sensors.
