A molecule is wired into an electronic circuit by attaching a metal nanoparticle
to the molecule and then electrically connecting a metal nanoparticle to the electric
circuit. The metal nanoparticle interconnects can bridge the gap between small
molecules and conventional electric circuits. An optical second harmonic also may
be generated by impinging optical radiation having a first frequency on an array
of molecularly bridged metal nanoparticles, to generate optical energy at a second
frequency that is twice the first frequency. Red to blue light conversion thereby
may be provided.
