ABSTRACT
Molecules existing in two or more states are particularly attractive
as molecular switches for molecular electronics applications. A
stimulusmay change suchmolecules between different redox states,
between translational isomers, between cis and trans isomers, between isomers of electrocyclic reactions, or between different
tautomers. This chapter describes how a variety of redox-and
photoactivemolecules can be used for conductance switching. It also
describes synthetic protocols for some of the switches.
