| Abstract;Double-helical DNA is a supramolecular architecture composed of stacked base-pairs of adenine-thymine and cytosine-guanine with complementary hydrogen bonds. We have reported that two-dimensional DNA mimetics composed of nucleobase monolayers were prepared at the air-water interface. In order to fabricate novel materials based on unique properties of stacked base-pairs, nucleobase amphiphiles with diacetylene and amphiphilic cytosine derivative with an azobenzene chromophore were newly synthesized. A-T pairs were formed in the mixed monolayers at the air-water interface. Photopolymerization of the diacetylene moiety in the mixed monolayer was observed as visible absorption change. The cytosine moiety of the monolayer can recognize guanosine at the air-water interface. J-aggregates of the azobenzene chromophores in the monolayer were formed at the air-water interface.
