  • High-density non-volatile memory devices incorporating thiol-derivatized porphyrin trimers
    Patent number: 6272038
    Abstract: The present invention provides high density, non-volatile memory devices incorporating winged trimers of porphyrinic macrocycles. In preferred embodiments, the two wing porphyrinic macrocycles are the same, and both are different from the center macrocycle. Such molecules are relatively easy to synthesize, have four different and distinguishable oxidation states, and thus provide molecules, information storage media and apparatus that store two bits of information.
