Jean Marie Lehn is a prestigious French scientist for winning, among others, the Nobel Prize in Chemistry. However, it seems to have discovered the first element of future molecular computers. In the molecules called Thiophene has detected a curious phenomenon. When they cross the ultraviolet lights they become conductors, but when they change the frequency of the light and cross the infrared rays, they cut the circuit, that is, they act as switches. It can be an optical treatment element of information.
