    Abstract

    Pressure-area isotherm of a ternary component monolayer of nucleobase amphiphiles, diacetylene-containing adenine and thymine amphiphiles (DA-Ade and DA-Thy), and octadecylcytosine (C18-Cyt), on the aqueous dT30 subphase was changed by addition of poly(G) into the subphase. Photopolymerization of the ternary monolayers on the aqueous dT30 solution was almost identical with that of a binary monolayer (DA-Ade/DA-Thy) on the same subphase. Addition of poly(G) into the subphase suppressed photopolymerization of the ternary monolayer. Since the DA-Ade/DA-Thy pairs complexed with dT30 were clustered in the C18-Cyt matrix, both intra- and inter-complex polymerization were occurred on the dT30 subphase. The inter-complex polymerization was restrained by mixing with C18-Cyt / poly(G) matrix.
