Polycyclic aromatic bridges for molecular electronic sensors

摘要

In various embodiments, synthetic bridging molecules usable in molecular electronic sensors are disclosed. In various embodiments, the bridging molecules comprise a molten ring polycyclic aromatic hydrocarbon structure in the shape of a long, narrow ribbon, with terminal groups on opposite short ends for selective binding to metal electrodes, a long for binding to a probe molecule. one or more substituents near the middle portion of the edge, and one or more additional substituents for solubility or other effects. In various embodiments, the bridging molecules herein are conductive and provide a closed circuit to the sensor when forming a bridge between gapped electrodes.
