ORGANIC ULTRATHIN FILM, CUMULATE THEREOF AND PROCESS FOR PRODUCING THE SAME

摘要

A novel organic ultrathin film characterized in that an amphipathic compound having a pigment group and a nucleic acid base is aligned due to base-pairing with an oligonucleotide which is capable of forming a base pair with the nucleic acid base to thereby constitute a monomolecular film. In this organic ultrathin film, a free space is provided around a pigment molecule so as to enable photoisomerization of the pigment molecule in a high-density solid state. Thus, it is useful as a photomemory, etc.
