Abstract:
This Focus Review provides an overview of the design and fabrication of new families of molecular electronic devices where reaction chemistry is an efficient means for covalently bridging the nanogaps between separated contacts. In each case ever-reducing top-down device fabrication existing in the silicon-based semiconductor industry is tailored to meet the requirements of ever-expanding length scales of bottom-up assembly. The combination of directed self-assembly and programmed chemical reactions with device fabrication allows us to modify the electrodes and then to complete electrical circuits by chemically connecting the electrodes.

Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
