Each molecular component performs one or more single acts , while the entire device performs one or more complex functions , characteristic of the assembly. Molecular devices, like macroscopic ones, need energy to operate.
Light is the most convenient form of energy to make molecular devices work.
The properties of these systems are studied by conventional absorption and emission spectroscopy, photochemical methods, time-resolved emission techniques, and electrochemical methods.
