The impending breakdown in Moore's Law has prompted the search for molecule-based information processing components such as molecular switches and logic gates. Molecules that can exist in two states with distinct absorbance or fluorescence behaviour have attracted considerable interest for Boolean logic operations. We are pursuing molecules that can exist in more than two states, and for which the "read-out" is via a change in nonlinear optical properties.
