The concept of dual-mode stimulation can be expanded further. It is possible to devise systems capable of existing in several forms (multistate) that can be intercon-verted by different external stimuli (multifunctional). Such systems can give rise to intricate networks of reactions that, when examined from the viewpoint of molecular-level devices"1311 reveal very interesting properties.1321... 

Synthetic flavylium compounds can exist in several forms (multistate), which can be interconverted by more than one type of external stimulus (multifunctional). The intricate network made up by their reactions, when examined from the viewpoints of molecular level devices and molecular level logic functions , reveals that these systems exhibit very interesting properties.
