ABSTRACT:
A modulatory molecular element includes a chain of molecules A and molecules Bi. The molecules A alternate with the molecules Bi and are bound to the adjacent molecules Bi. The molecules A are selected from common molecules. The molecules Bi are selected from at least two different types of molecules. The molecules Bi are changeable from first stable states to second stable states in response to applied stimulative energy. The molecules Bi return from the second stable states to the first stable states at different relaxation time constants dependent on the types of the molecules Bi when the applied stimulative energy is removed. The chain has a physical property which depends on whether or not all the molecules Bi are in the second stable states.
